Export _libc_arm_fpu_present as a private symbol to be used by other
system libraries, for example libm.
On armv6 access both the softfloat and, when available, the vfp to get and
set the floating-point environment.
Build fenv-vfp.c with the softfp float abi. Without this gcc generates an
incorrect assembly file that doesn't allow for vfp instructions.
Only build the vfp/softfp switching code on armv6 as we don't support vfp
on anything earlier than this. This should fix the armeb and arm builds
when using gcc.
Add an optimised version of the float and double helper functions.

263030, 263033, 263034, 263056, 263057,
Remove all the redundant external declarations of exception vectors and
runtime setting of the pointers that's scattered around various places.
Remove all traces of support for ARM chips prior to the arm9 series.
Make the default exception handler vectors point to where I thought they
were already pointing: the default handlers (not a panic that says there
is no default handler).
Eliminate irq_dispatch.S. Move the data items it contained into
arm/intr.c and the functionality it provided into arm/exception.S.
Move the exception vector table (so-called "page0" data) into exception.S
and eliminate vectors.S.
Change the way the asm GET_CURTHREAD_PTR() macro is defined so that code
using it doesn't have to have an "AST_LOCALS" macro somewhere in the file.
Arrange for arm fork_trampoline() to return to userland via the standard
swi_exit code in exception.S instead of having its own inline expansion
of the DO_AST and PULLFRAME macros.
Now that the PUSHFRAME and PULLFRAME macros are used only in the swi
entry/exit code, they don't need to be macros. Except that didn't work
and the whole change was reverted.
Remove some unnecessary indirection and jump right to the handler functions.
Use panic rather than printf to "handle" an arm26 address exception
(should never happen on arm32).
Remove the unreferenced DATA() macro.
Remove #include <machine/asmacros.h> from files that don't need it.

Use the new -d option that was added to tblgen between llvm/clang 3.3
and 3.4 to generate dependency files for the '.inc.h' files generated
from .td files, and .sinclude those dependency files in clang.build.mk.
This will make future incremental builds of lib/clang and usr.bin/clang
work correctly, whenever any of the .td files get modified.
Note that this will not fix any problems with incremental builds from
*before* this revision, since there will not yet be any generated
dependency files. A quick workaround is to run the following:
find /usr/obj -type f -name '*.inc.h' | xargs rm
and then a regular incremental buildworld (e.g. with -DNO_CLEAN).

Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture.
Move all the files named foo/common.c to foo/foo_common.c
Initial cut for DTS on the hl201 board.
Add commented out dts for sam9260ek as well as early printf support.
Make clock optional on uart nodes, then back it out ("I don't know what I
was thinking, but it is lame.")
Set the baud rate if it isn't 0
Make at91_soc_id() public.
Properly round at91 resource on unmapping.
Move AT91 AIC related stuff to own file.
Fix another bug in multicast filtering. i.MX uses 6 bits from MSB in
LE CRC32 for the hash value, not the lowest 6 bits in BE CRC32.
Follow r262916 with one more config file that references a renamed common.c
Remove bogus AT91 define that causes compile errors. Most of the defines
for SAM9X are going away soonish anyway (once FDT works), but until
then...
Remove all dregs of a per-thread undefined-exception-mode stack.
Rework the VFP code that handles demand-based save and restore of state.
Always call vfp_discard() on thread death.
When a thread begins life it doesn't own the VFP hardware state on any cpu.

ffec: Fix multicast filtering.
Allwinner a10/a20...
- Add gpio and clock bits for A10/A20's EMAC ethernet controller driver
- EMAC gpio configuration
- EMAC clock activation
- Add Static Random Access Memory controller driver for A10/A20.
A10/A20's SRAM is used by devices, such as CPU, EMAC,
for extra fast memory or as cache.
- Add EMAC 10/100 Ethernet controller driver for A10/A20.
It is available mostly in A10 devices like Hackberry, Marsboard,
Mele A1000, A2000, A100 HTPC, cubieboard1 and A20 device
like cubieboard2.
TX performance can be improved using both channels 0 and 1.
RX performance is poor and needs improvement with the assistance of
external DMA controller in case there
- Add EMAC and SRAM controller entries to FDT.
- Add EMAC device to kernel config files and enable EMAC, SRAM drivers.
OMAP: When calculating the MPU freq, make sure not to overflow.
Vybrid:
- Add driver for Port control and interrupts (PORT).
- Export panel info to DTS
- Reset all the layers before setup first one
- Enable display
nandfs: Slight code reordering to make error branch last.
Add option TMPFS to arm/conf/DEFAULTS, remove it from the few configs
that have it individually. Concensus on freebsd-arm@ is that it should
be included in all ARM kernels.
Fix the arm sys_sigreturn(): its argument is a struct ucontext, not a
struct sigframe containing the struct ucontext.

Integrate device-tree upstream files into the build process:
(1) Invoke cpp to bring in files via #include (although the old
/include/ stuff is supported still).
(2) bring in files from either vendor tree or freebsd-custom files
when building.
(3) move all dts* files from sys/boot/fdt/dts to
sys/boot/fdt/dts/${MACHINE} as appropriate.
(4) encode all the magic to do the build in sys/tools/fdt/make_dtb.sh
so that the different places in the tree use the exact same logic.
(5) switch back to gpl dtc by default. the bsdl one in the tree has
significant issues not easily addressed by those unfamiliar with
the code.
Only try to build the static dtb when we're building a static dtb.
Use proper include path for dtc as well as cpp.
Fix syntax errors (missing ; other minor glitches) in existing dts files.

r260522:
Add the manual page for geom_uncompress(4).
r260523:
Build the geom_uncompress(4) module by default.
Fix geom_uncompress(4) module loading. Don't link zlib.c (which is a module
itself) directly.
r261439:
Remove some unnecessary code. The offsets read from the first block are
overwritten a few lines bellow.
r261440:
Fix a logic error. Because of this inflateReset() wasn't being called and
the output buffer wasn't being cleared between the inflate() calls,
producing zeroed output after the first inflate() call.
This fixes the read of mkuzip(8) images with geom_uncompress(4).
r261586:
Fix the build with DEBUG enabled. Where possible, fix style(9) issues.
r264504:
Make sure not to do I/O for more than MAXPHYS bytes. Doing so can cause
problems in our providers, such as a KASSERT in md(4). We can initiate
I/O for more than MAXPHYS bytes if we've been given a BIO for MAXPHYS
bytes, the blocks from which we're reading couldn't be compressed and
we had compression in preceeding blocks resulting in misalignment of
the blocks we're trying to read relative to the sector. We're forced to
round up the I/O length to make it an multiple of the sector size.
When we detect the condition, we'll reduce the block count and perform
a "short" read. In g_uzip_done() we need to consider the original I/O
length and stop early if we're about to deflate a block that we didn't
read. By using bio_completed in the cloned BIO and not bio_length to
check for this, we automatically and gracefully handle short reads that
our providers may be doing on top of the short reads we may initiate
ourselves.
r264769:
Keep geom_uncompress(4) in line with geom_uzip(4), bring in the r264504 fix.
Make sure not to start I/O bigger than MAXPHYS bytes.
r265193:
Some style and whitespace fixes. Reduce the difference between geom_uzip(4)
and geom_uncompress(4). Now, they produce an almost clean diff(1) output.
Remove a duplicated variable from g_uncompress.c and an unnecessary header
from g_uzip.c.
r265194:
Actually the FEATURE() macro is defined on sys/sysctl.h.
r265197:
Fix a leak in g_uzip_taste(). After retrieve all the block offsets from
the uzip image, free the last data read.

Disable TX IP/TCP/UDP checksum offloading for RTL8168C/RTL8168CP.
Previously only TX IP checksum offloading was disabled but it's
reported that TX checksum offloading for UDP datagrams with IP
options also generates corrupted frames. Reporter's controller is
RTL8168CP but I guess RTL8168C also have the same issue since it
shall share the same core.

Replace many pasted identical definitions of cpu_initclocks() with a common
implementation in arm/machdep.c.
aicasm: Don't complain about missing prototypes to ease bootstrap issues.
Vybrid: Add driver for Inter-Integrated Circuit (I2C).
imx6: Initialize the Low Power Mode bits to keep the ARM cores running
during WFI.
All our current ARM multi-core systems have all cores in one package with
a shared L2 cache, reflect that in the common cpu_topo() routine.
mpcore timer: Supply a DELAY() implementation via weak linkage, so that
SoC-specific code can supply a better implementation.
imx6: Add some rudimentary voltage control.
Add an armv7 implementation of cpu_sleep().
Add __used attribute so that the DELAY implementation doesn't get
optimized away as unreferenced, causing linker errors when trying to
resolve the weak reference to the missing function.

As of r257209, all architectures have defined
VM_KMEM_SIZE_SCALE. In other words, every architecture is now
auto-sizing the kmem arena. This revision changes kmeminit() so
that the definition of VM_KMEM_SIZE_SCALE becomes mandatory and
the definition of VM_KMEM_SIZE becomes optional.
Replace or eliminate all existing definitions of VM_KMEM_SIZE.
With auto-sizing enabled, VM_KMEM_SIZE effectively became an
alternate spelling for VM_KMEM_SIZE_MIN on most architectures.
Use VM_KMEM_SIZE_MIN for clarity.

If the L2 cache type is PIPT, pass a physical address for a flush.
Actually set the proper bit to indicate TTB shared memory.
Add a new cache maintenance function, idcache_inv_all, to the table, and

Invalidate caches immediately upon entry to init_secondary(). Also set
the Bufferable bit in the PDE entries of the secondary processor startup
pagetables.

Add Vybrid driver for Synchronous Audio Interface (SAI).
Decrease SAI buffer size. Handle eDMA interrupt on running channel only.
Give the physmem fdt helper routines static linkage since no global
definition of them is provided anywhere.
Add imx6 early printf support, wrapped in #if 0 because it's rarely needed.
Add basic cpu frequency control and temperature monitoring to imx6_anatop.
Add the FREEBSD_BOOT_LOADER option so that a loaded DTB passed in from
ubldr will actually get used.
Create a generic IMX6 kernel config, then fix it to have an ident line.
Don't force imx6 bootverbose on anymore, it can be set from ubldr now.

r261955, r261958,
Add a driver to provide access to imx6 on-chip one-time-programmble data.
Make it possible to access the ocotp registers before the ocotp device
is attached, by establishing a temporary mapping of the registers when
necessary.
It turns out Freescale cleverly made the ocotp device compatible across
several different families of SoCs, so move it to the freescale directory
and prefix everything with fsl rather than imx6.
Convert the imx6 sdhci "R1B fix" from a busy-loop in the interrupt handler
to a callout.
Increase the wait time for acquiring the SD bus from 10 to 250ms.
If no compatible cards were found after probing the SD bus, say so.
Add timeout logic to sdhci, separate from the timeouts done by the hardware.
After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA
rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing
any possibility of recovering from the error.
Add a helper routine to depth-search the device tree for a node with a
matching 'compatible' property.

On armv6 and later, use the WriteNotRead bit of the fault status register
to decide what protections are required by the faulting access.
Use the right symbols for determining arm architecture. Include the
necessary header file which has the new FAULT_WNR symbol defined in it.
Allow the kernel to be loaded at any 1MiB address. This requirement is
because we use the 1MiB section maps as they only need a single pagetable.
Add function for configuring Vybrid PLL4 (Audio) clock frequency output.
imx6 changes ...
- Fix the definition of the SDHCI_STATE_DAT and SDHCI_STATE_CMD fields,
and add SDHCI_RETUNE_REQUEST. None of these are actually used in the
code yet.
- Write translation code for the SDHCI_PRESENT_STATE register.
Freescale moved some bits around in their version of the register,
adjust things so that the sdhci code sees the standard layout.
- Add standard non-removable and cd-gpios properties to the usdhc
devices. That generates references to gpio devices, so uncomment them
even though there isn't a gpio driver to do anything with them yet.
- Add handling of standard "non-removable" property, and also some
workaround code so that if card detect is wired to a gpio pin, for now
we just treat it the same as non-removable (because there isn't a gpio
driver yet).
- Enable both sdcard slots, but not the sdio-based wifi that we don't
yet have a driver for.
- Remove a couple obsolete function declarations.

Rework the EARLY_PRINTF mechanism. Instead of defining a special eprintf()
routine, now a platform can provide a pointer to an early_putc() routine

during standard console init.

Consolidate code related to setting up physical memory configuration into
a new physmem.c file.
Replace compile-time constant KERNPHYSADDR with abp_physaddr
Calculate the kernel's load address from the PC in the elf / gzip
trampoline instead of relying on KERNPHYSADDR as a compile-time constant.
It turns out a global variable is the only straightforward way to
communicate the kernel's physical load address from where it's known in
initarm() into cpu_mp_start() which is called from non-arm code and
takes no parameters.
Remove the now unused MMU_INIT macro.
Use vm_paddr_t, not vm_offset_t, when dealing with physical addresses.
No need to set physmem in each initarm() instance anymore, it's handled
in common code now.
Pass the pagetable used from locore.S to initarm to allow it to map data
in as required.
Fix the physmem exclude-region clipping logic for the edge-trim case.
Add some extra debugging output when DEBUG is defined.
Update legacy platforms to use new arm_physmem helper routines.
