1e3ce2b854 ARN: at91: introduce SOC_AT91xxx define to allow to compile SoC core support
We can now compile all SoC core support together and DT boards.
We still can not compile together the non DT board.
So We keep the ARCH_AT91xxx for the non DT board and for backward defconfig
compatibility. This will enable the plaform_device ressources.

5f29d0a0ee ARM: at91: uncompress: autodetect the uart to use
This will now autodetect the first uart enabled by the bootloader
and will use it for uncompress. This will still assume that the bootloader
configured it (pins and clock).

This also allows to include all soc headers together.

Create a new device tree source file for Atmel at91sam9g45 SoC family.
The Evaluation Kit at91sam9m10g45ek includes it.
This first basic support will be populated as drivers and boards will be
converted to device tree.
Contains serial, dma and interrupt controllers.

The generic board file still takes advantage of platform data for early serial
init. As we need a storage media and the NAND flash driver is not converted to
DT yet, we keep old initialization for it.

fdcad71cef at91: at91sam9g20ek modify dual slot evaluation kit
at91sam9g20ek rev. C and onwards embed two SD/MMC slots. This patch modify the
previous dual slot board definition to match the official rev. C board. It also
allows the use of at91_mci SD/MMC driver in addition to the atmel-mci one.

Some pins have been re-affected from leds or Ethernet phy IRQ to the SD/MMC
slot A. This lead to a modification of those definitions.

Created a modified version of the at91sam9g20 evaluation kit platform
(board-sam9g20ek-2slot-mmc.c) and device support to make use of the
updated atmel-mci driver.

As the use of two slots modify GPIO pin allocation, we create another
board file.

This requires getting the most updated arch/arm/tools/mach-types from
http://www.arm.linux.org.uk/developer/machines/download.php to have the machine
type for the at91sam9g20ek-2slot-mmc board.

eaad2db03c [ARM] 5264/2: [AT91] Suspend-to-RAM disables main oscillator
This patch adds support for a low(er)-power suspend-to-RAM.
In addition to the SDRAM being put into self-refresh mode, the Master
Clock is set to the Slow-clock rate (32Khz) and PLLA & PLLB are
disabled.
Certain peripherals are therefore also disabled, and thus cannot be
used as wakeup sources.

This patch has been included in the AT91 patches in various forms
since 2.6.19 and a number of people have worked or commented on it,
most notably:

f6ed6f78d4 Fix rename of at91_nand -> atmel_nand
Structs called at91_nand_data where renamed to atmel_nand_data
and configs called *MTD_NAND_AT91* where renamed to
*MTD_NAND_ATMEL*. This was unfortunately not done consistently,
causing NAND chips not being initialised on several ARM boards.

I am aware that the author of the original change did not rename
MTD_NAND_AT91_BUSWIDTH to MTD_NAND_ATMEL_BUSWIDTH, for example.
All *MTD_NAND_AT91* where renamed to *MTD_NAND_ATMEL* in order
to keep naming consistency.

This patch was only tested on a MACH_SAM9_L9260, as this is the
only ARM board I have to my disposal.

Before this patch:

$ git-ls-files |xargs grep atmel_nand |wc -l

$ git-ls-files |xargs grep at91_nand |wc -l

$ git-ls-files |xargs grep MTD_NAND_ATMEL |wc -l

ad48ce74f7 [ARM] 4989/1: [AT91] SAM9 ClockSource / ClockEvents
Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent
infrastructure:

 - Clocksource gives sub-microsecond timestamp precision, assuming
 memory is clocked at over 16 MHz.  It's less than a 32 bit counter,
 unless it's is also generating IRQs.

 - Clockevent device supports periodic mode only; no oneshot
 support from this hardware.  No IRQs generated unless it's the
 active clocksource.

Later, another timer (probably from a TC module) can provide a oneshot
clockevent device to get NO_HZ and High-Res-Timer behavior.

This also updates the timekeeping to use the actual master clock rate
on the system, instead of compile-time <asm/arch/timex.h> constants
matching what Atmel's EK boards use.  (Product boards may well differ!)

Plus cleanup:  rename "*_timer*" symbols to "*_pit*" (there are other
timers, but only one PIT); shorter lines; remove needless CPP stuff;
make several symbols static; etc.

Currently early kernel messages, i.e., those from uncompression, go to the
debugging UART. And if it is enabled in the platform configuration, but
not initialized by the bootloader, the machine hangs, waiting for UART
status change. Besides, having those messages on another UART - typically
the console UART - may be preferrable. This patch allows selecting the
UART in kernel configuration.

5e802dfab7 [ARM] 4539/1: clocksource and clockevents for at91rm9200
GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200.

 - Oneshot mode (used for NO_HZ and high res timers) uses the
   alarm to emulate a real oneshot timer; the trickiest bit is
   how to avoid some lowlevel races.  Thanks to Remy Bohmer for
   various fixes to this code.

 - Tighten up periodic mode support using the PIT.

 - Streamline reads of the 32KHz counter.  Thanks to Marc Pignat
   for some testing results: the CRTR register has *very* odd
   behavior.  The reread appears to work around stranger glitches
   than just getting an old clock value (which would quickly
   self-correct).

 - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100),
   since that no longer acts correct (time increases too fast).

Note that the at91sam9 and at91x40 chips need other solutions,
since they don't have the same system timer module.
