Since the debug macros no longer depend on the machine type information,
the machine type lookup can be deferred to setup_arch() in setup.c which
simplifies the code somewhat.
We also move the __error_a functionality into setup.c for displaying a
message when a bad machine ID is passed to the kernel via the LL debug
code. We also log this into the kernel ring buffer which makes it
possible to retrieve the message via a debugger.

The use of shadow registers caused memory corruption at physical
address 0 because the enable bit was not shadowed, and assuming it
needed to be set would enable an unconfigured dma block. Most of the
register accesses don't need to know the previous state of the
registers, and the few places that do need to modify only a few bits
in the registers are the same ones that were sometimes incorrectly
setting the enable bit. This patch convert tegra_dma_update_hardware

and drops the shadow registers completely.

This patch fixes a wrongly used lcd enable pin.
The Devkit8000 uses twl4030_ledA configured as output gpio only for
the lcd enable line. twl4030_gpio.1 is used through the generic
gpio functions while ledA is used via low level twl4030 calls.
This patch removes the low level calls and use the generic gpio functions
for initialization and use of ledA. This patch also fixes a bug where the
lcd would not power down when blanking.
Further this patch fixes an indentation issue. The comment line uses
eight whitespace and is replaced with a hard tab.
gpio_request + gpio_direction_output are replaced with gpio_request_one.
The return value of gpio_request_one is used to set the value of the
gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the
unsuccessful request. But already successful requested gpios are not freed.

Allow non-ARM SMP processors to use the SMP_ON_UP feature. CPUs
supporting SMP must have the new CPU ID format, so check for this first.
Then check for ARM11MPCore, which fails the MPIDR check. Lastly check
the MPIDR reports multiprocessing extensions and that the CPU is part of

The Footbridge platforms have some reasonable timers in the host bridge,
which we use for most footbridge-based platforms. However, NetWinder's
clock these using a spread-spectrum clock which makes them too unstable
for time keeping. So we have to rely on the PIT.
Convert both Footbridge timers and PIT timers to use the clocksource
and clockevent infrastructure. Tested on Netwinder.

Disable the initrd if the passed address already overlaps the reserved

In low-level board support code, there is sometimes a need to
copy a function body to another location at run-time.
A straightforward call to memcpy doesn't work in Thumb-2,
because bit 0 of external Thumb function symbols is set to 1,
indicating that the function is Thumb. Without corrective
measures, this will cause an off-by-one copy, and the copy
may be called using the wrong instruction set.
This patch adds an fncpy() macro to help with such copies.
Particular care is needed, because C doesn't guarantee any
defined behaviour when casting a function pointer to any other
type. This has been observed to lead to strange optimisation
side-effects when doing the arithmetic which is required in
order to copy/move function bodies correctly in Thumb-2.

init by the save secure RAM code. Rather than forcing the state of
MPU powerdomain to on, simply read the current value and restore it
after the ROM code has run.
This only affects the !CPUidle case since when CPUidle is enabled, the
MPU power state is dynamically changed by CPUidle. In the !CPUidle

Always allow backtraces when using oprofile on ARM, even if a PMU
isn't present. Restores functionality originally introduced in commit
1b7b56982f ("oprofile: Always allow
backtraces on ARM") by Richard Purdie.
It is not that obvious, but there is now only one oprofile_arch_init()
function. So the .backtrace callback is available also in timer mode.
Implemented by removing code and using stubs for oprofile_perf_{init,
exit} provided by <linux/oprofile.h>. This allows cleaning of other
architecture specific implementations too.

The -rt patches change the console_semaphore to console_mutex. As a
result, a quite large chunk of the patches changes all

This commit makes things use more neutral function names which dont make

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()
This patch also paves the way to switching console_sem from a semaphore to

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface
peripheral. At power-up they default into non-GPIO mode with the Key
Matrix controller enabled so these ports are unusable for GPIO. Note
that the Keypad Interface peripheral is only available in the EP9307,
EP9312, and EP9315 processor variants.
The keypad support will clear the DeviceConfig bits appropriately to
enable the Keypad Interface when the driver is loaded. And, when the
driver is unloaded it will set the bits to return the ports to GPIO mode.
To make these ports available for GPIO after power-up on all EP93xx
processor variants, set the KEYS and GONK bits in the DeviceConfig
register.
Similarly, the E, G, and H ports are multiplexed with the IDE Interface
peripheral. At power-up these also default into non-GPIO mode. Note
that the IDE peripheral is only available in the EP9312 and EP9315
processor variants.
Since an IDE driver is not even available in mainline, set the EONIDE,
GONIDE, and HONIDE bits in the DeviceConfig register so that these
ports will be available for GPIO use after power-up.

Timers on Versatile Express mainboard are used as system clock/event

Old V2M firmware apparently configured it by default, but on newer
boards one can observe that "sleep 1" command takes over 30 seconds
to finish, as the timers are fed with 32kHz instead...

This allows a ROM-able zImage to be written to MMC and
for SuperH Mobile ARM to boot directly from the MMCIF
hardware block.
This is achieved by the MaskROM loading the first portion
of the image into MERAM and then jumping to it. This portion
contains loader code which copies the entire image to SDRAM
and jumps to it. From there the zImage boot code proceeds
as normal, uncompressing the image into its final location
and then jumping to it.

* Move mmcif_loader to be earlier in the image and

* Move LED GPIO initialisation into mmcif_progress_init

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

For omap15xx and 730 we need to use the MPU timer

Commit 56a6a19dff ("omap2plus: prm:
Trvial build break fix for undefined reference to
'omap2_prm_read_mod_reg'") generates a lot of warnings on boot since
clockdomain functions that manipulate wake-up dependencies are not
implemented yet on OMAP4 for 2.6.38. This patch bypasses the OMAP2/3
functions on OMAP4, which in turn avoids the warnings when the
functions would attempt to call the underlying OMAP2/3 PRCM functions.
A one-line warning is still logged from the clockdomain code that the
OMAP4 wake-up dependency code is not yet implemented.
A clockdomain wake-up and sleep dependency implementation for OMAP4
from Rajendra should be possible to merge during the 2.6.39 merge
window:

Do not use memory bank info to request the "system ram" resources as
they do not track holes created by memblock_remove inside
machine's reserve callback. If the removed memory is passed as
platform_device's ioresource, then drivers that call
request_mem_region would fail due to a conflict with the incorrectly
configured system ram resource.
Instead, iterate through the regions of memblock.memory and add
those as "System RAM" resources.

Four architectures (arm, mips, sparc, x86) use __vmalloc_area() for
module_init(). Much of the code is duplicated and can be generalized in a
globally accessible function, __vmalloc_node_range().
__vmalloc_node() now calls into __vmalloc_node_range() with a range of
[VMALLOC_START, VMALLOC_END) for functionally equivalent behavior.
Each architecture may then use __vmalloc_node_range() directly to remove
the duplication of code.
