On other platforms with CESA accelerator the SRAM memory is mapped in
early init before driver is attached. This method only works correctly
with mappings no smaller than L1 section size (1MB). There may be more
SRAM blocks and they may have smaller sizes than 1MB as is the case
for Armada38x. Instead, map SRAM memory with bus_space_map() in CESA
driver attach. Note that we can no longer assume that VA == PA for the
SRAM.

have ACLE support built in. The ACLE (ARM C Language Extensions) defines
a set of standardized symbols which indicate the architecture version and
features available. ACLE support is built in to modern compilers (both
clang and gcc), but absent from gcc prior to 4.4.
ARM (the company) provides the acle-compat.h header file to define the
right symbols for older versions of gcc. Basically, acle-compat.h does
for arm about the same thing cdefs.h does for freebsd: defines
standardized macros that work no matter which compiler you use. If ARM
hadn't provided this file we would have ended up with a big #ifdef __arm__
section in cdefs.h with our own compatibility shims.
Remove #include <machine/acle-compat.h> from the zillion other places (an
ever-growing list) that it appears. Since style(9) requires sys/types.h
or sys/param.h early in the include list, and both of those lead to
including cdefs.h, only a couple special cases still need to include
acle-compat.h directly.

and places where the old armv4 cpufuncs mechanism is used), annotate the
accesses with a comment that includes SCTLR. Now a grep -i sctlr can find
all the system control register manipulations.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.
This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.

struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.
There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.
While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.
This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.

universal.
(1) New struct intr_map_data is defined as a container for arbitrary
description of an interrupt used by a device. Typically, an interrupt
number and configuration relevant to an interrupt controller is encoded
in such description. However, any additional information may be encoded
too like a set of cpus on which an interrupt should be enabled or vendor
specific data needed for setup of an interrupt in controller. The struct
intr_map_data itself is meant to be opaque for INTRNG.
(2) An intr_map_irq() function is created which takes an interrupt
controller identification and struct intr_map_data as arguments and
returns global interrupt number which identifies an interrupt.
(3) A set of functions to be used by bus drivers is created as well as
a corresponding set of methods for interrupt controller drivers. These
sets take both struct resource and struct intr_map_data as one of the
arguments. There is a goal to keep struct intr_map_data in struct
resource, however, this way a final solution is not limited to that.
(4) Other small changes are done to reflect new situation.
This is only first step aiming to create stable interface for interrupt
controller drivers. Thus, some temporary solution is taken. Interrupt
descriptions for devices are stored in INTRNG and two specific mapping
function are created to be temporary used by bus drivers. That's why
the struct intr_map_data is not opaque for INTRNG now. This temporary
solution will be replaced by final one in next step.

This commit provides attachment of xhci-platform for A38X boards, making
it possible to mount FreeBSD world from USB3.0 flash. 'xhci' device was
added to files.mv (as optional) and kernconf of Armada38x was enhanced.
It was also necessary to open programmable memory windows of USB3.0.
fdt_win_setup needed improvement so it's able to traverse through
children of internal-regs node.

After ARM_INTRNG introduction, MPIC code needed several modifications:
- IRQ resource and its handler added
- several DEVMETHODs of INTRNG interface implemented
- defines enhanced to ensure code compiles as well for AXP as for A38X
- added dummy MSI_IRQ, ERR_IRQ defines for Armada38x
- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in
kernconf file and regs of MPIC corrected in dts file.
Instead of modifying Armada38X DTS, offsets to CPU registers defined in
driver were changed. That required restoring 'reg' property of mpic node
in ArmadaXP to state compliant with Linux DTS.
Additionally, required ARM_INTRNG definitions were added to mv_common.c.

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of
u_long.
Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

This is a stub for PMSU driver. Note that it cannot be used to set the
secondary core boot address during attach because drivers are attached
later than SI_SUB_CPU sysinit where cores are started.
Setting the boot address should be done manually in platform_mp_start_ap().
SMP is working fine with this commit and was enabled in Armada38x kernel
configuration file.
