Based on an original patch from Michael Schmitz:
Because mem_init() is now called before device init, devices that rely on
ST-RAM may find all ST-RAM already allocated to other users by the time
device init happens. In particular, a large initrd RAM disk may use up
enough of ST-RAM to cause atari_stram_alloc() to resort to
__get_dma_pages() allocation.
In the current state of Atari memory management, all of RAM is marked
DMA capable, so __get_dma_pages() may well return RAM that is not in actual
fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes
subtle failure.
The ST-RAM allocator has been changed to allocate memory from a pool of
reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e.
before mem_init()). As long as this pool is not exhausted, allocation of
real ST-RAM can be guaranteed.
Other changes:
- Replace the custom allocator in the ST-RAM pool by the existing allocator
in the resource subsystem,
- Remove mem_init_done and its hook, as memory init is now done before
device init,
- Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g.
005f2000-006f1fff : ST-RAM Pool
005f2000-0063dfff : atafb
0063e000-00641fff : ataflop

The address that's passed to _sparc_find_resource() should always be the
start address of a resource:
- iounmap() passes a page-aligned virtual address, while the original
address was created by adding the in-page offset to the resource's
start address,
- sbus_free_coherent() and pci32_free_coherent() should be passed an
address obtained from sbus_alloc_coherent() resp. pci32_alloc_coherent(),
which is always a resource's start address.
Hence replace the range check by a check for an exact match.

As of commit 5df1abdbd37af2ae317a1c5b5944173284dc55d6 ('m68k/amiga: Fix
"debug=mem"'), "debug=mem" no longer uses amiga_chip_alloc_res(), so we
can remove the hack to prefer memory at the safe end.
This allows to simplify the code and make amiga_chip_alloc() just call
amiga_chip_alloc_res() internally.

Commit 6e8af08dfa40b747002207d3ce8e8b43a050d99f enables pci=bfsort on
future Dell systems. But the identification string 'Dell System' matches
on already existing whitelist, which do not have SMBIOS type 0xB1,
causing pci=bfsort not being set on existing whitelist.
This patch fixes the regression by moving the type 0xB1 check beyond the
existing whitelist so that existing whitelist is walked before.

Aside of the usual motivation for constification, this function has a
history of being abused a hook for interrupt and other fixups so I turned
this function const ages ago in the MIPS code but it should be done
treewide.
Due to function pointer passing in varous places a few other functions
had to be constified as well.

Without this change, the majority of the raw PCI config space access
functions silently ignore a non-zero segment argument, which is
certainly wrong.
Apart from pci_direct_conf1, all other non-MMCFG access methods get
used only for non-extended accesses (i.e. assigned to raw_pci_ops
only). Consequently, with the way raw_pci_{read,write}() work, it would
be a coding error to call these functions with a non-zero segment (with
the current call flow this cannot happen afaict).
The access method 1 accessor, as it can be used for extended accesses
(on AMD systems) instead gets checks added for the passed in segment to
be zero. This would be the case when on such a system having multiple
PCI segments (don't know whether any exist in practice) MMCFG for some
reason is not usable, and method 1 gets selected for doing extended
accesses. Rather than accessing the wrong device's config space, the
function will now error out.
v2: Convert BUG_ON() to WARN_ON(), and extend description as per Ingo's
request.

Host bridge windows are top-level resources, so if we find a host bridge
window conflict, it's probably with a hard-coded legacy reservation.
Moving host bridge windows is theoretically possible, but we don't support
it; we just ignore windows with conflicts, and it's not worth making this
a user-visible error.

Direct access is needed in mmconf mode too. There are two reasons:
1. we need it to access first 256 bytes. We have bug before that
using mmconf to access pci config space hangs system (when
resizing BARs), so we use type1 config for legacy config space.
2. when doing mmconfg bar checking, we need access ACPI _CRS,
which might access PCI config space.

instead of reading the registers everytime
the current implementation respect the following constrain:
- allow 1 to n soc to be enabled
- allow to have a virtual cpu type and subtype
- always detect the cpu type and subtype and report it
- detect if the soc support is enabled
- prepare for sysfs export support
- drop soc specific code via compiler when the soc not enabled
(via cpu_is_xxx)
Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too
with the new implementation we just need to check the soc subtype
this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.
this implementation is inspired by the SH cpu detection support

On all at91 except rm9200 and x40 have the System Controller starts
at address 0xffffc000 and has a size of 16KiB.
On rm9200 it's start at 0xfffe4000 of 111KiB with non reserved data starting
at 0xfffff000
This patch removes the individual definitions of AT91_BASE_SYS and
replaces them with a common version at base 0xfffffc000 and size 16KiB
and map the same memory space

It might be not good to use software defined version to identify sdma
device type, when hardware does not define such version. Instead,
soc name is stable enough to define the device type.
The patch uses platform_device_id rather than version number passed
by platform data to identify sdma device type/version.

The patch extends card_detect and write_protect support to get mx5
family and more scenarios supported. The changes include:
* Turn platform_data from optional to mandatory
* Add cd_types and wp_types into platform_data to cover more use
cases
* Remove the use of flag ESDHC_FLAG_GPIO_FOR_CD
* Adjust some machine codes to adopt the platform_data changes
* Work around the issue that software reset will get card detection
circuit stop working
With this patch, card_detect and write_protect gets supported on
mx5 based platforms.

On the recent i.mx (mx25/50/53), there is a gasket inside fec
controller which needs to be enabled no matter phy works in MII
or RMII mode.
The current code enables the gasket only when phy interface is RMII.
It's broken when the driver works with a MII phy. The patch uses
platform_device_id to distinguish the SoCs that have the gasket and
enables it on these SoCs for both MII and RMII mode.

The patch removes all the uses of cpu_is_mx1(). Instead, it uses
the .id_table of platform_driver to distinguish the uart device type,
IMX1_UART and IMX21_UART. The IMX21_UART type runs on all i.mx
except i.mx1.
A couple of !cpu_is_mx1 logic gets turned into is_imx21_uart,
as the codes wrapped there are really IMX21 type uart specific.
It also removes macro MX1_UCR3_REF25 and MX1_UCR3_REF30 which are
not used anywhere.

Everything required to populate NVIDIA Tegra devices from the device
tree. This patch adds a new DT_MACHINE_DESC() which matches against
a tegra20 device tree. So far it only registers the on-chip devices,
but it will be refined in follow on patches to configure clocks and
pin IO from the device tree also.

For testing the dt work, define a dt-enabled versatile platform.
This patch adds a new versatile platform for when using the device
tree. Add platform and amba devices are discovered and registered by
parsing the device tree. Clocks and initial io mappings are still
configured statically.
This patch still depends on some static platform_data for a few devices
which is passed via the auxdata structure to of_platform_populate(),
but it is a viable starting point until the drivers can get all
configuration data out of the device tree.

This patch adds irq_domain infrastructure for translating from
hardware irq numbers to linux irqs. This is particularly important
for architectures adding device tree support because the current
implementation (excluding PowerPC and SPARC) cannot handle
translation for more than a single interrupt controller. irq_domain
supports device tree translation for any number of interrupt
controllers.
This patch converts x86, Microblaze, ARM and MIPS to use irq_domain
for device tree irq translation. x86 is untested beyond compiling it,
irq_domain is enabled for MIPS and Microblaze, but the old behaviour is
preserved until the core code is modified to actually register an
irq_domain yet. On ARM it works and is required for much of the new
ARM device tree board support.
PowerPC has /not/ been converted to use this new infrastructure. It
is still missing some features before it can replace the virq
infrastructure already in powerpc (see documentation on
irq_domain_map/unmap for details). Followup patches will add the
missing pieces and migrate PowerPC to use irq_domain.
SPARC has its own method of managing interrupts from the device tree
and is unaffected by this change.
