Nicolas Ferre bb413db591 AT91: reset: extend alternate reset procedure to several chips
Several at91sam9 chips need the alternate reset procedure to be sure to halt
SDRAM smoothly before resetting the chip.
This is an extension of previous patch "Fix AT91SAM9G20 reset" to all chips
affected.

Nicolas Ferre 1345562b44 AT91: reset routine cleanup, remove not needed icache flush
Generalize assembler reset routine to allow use on several at91sam9 chips.
This patch replace double definitions of SDRAM controller registers and RSTC
registers with use of classical header files.

For this rework, we remove the not needed icache flush as it is already
done in the calling function: arm_machine_restart().

Rename at91sam9g20_reset.S to generalize to several chips.

Peter Horton 184c82e853 AT91: Fix AT91SAM9G20 reset as per the errata in the data sheet
If the SDRAM is not cleanly shutdown before reset it can be left driving
the bus, which then stops the bootloader booting from NAND.

sedji gaouaou 613526677a [ARM] 5130/4: Support for the at91sam9g20
Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.

AT91sam9g20 is an evolution of the at91sam9260 with a faster clock
speed.
We created a new board for this device but based the chip support
directly on 9260 files with little updates.
Here is the chip page on Atmel wabsite:

Andrew Victor f7eee89b2a [ARM] 4192/1: AT91: Support for AT91SAM9XE processors.
Add support for the Atmel AT91SAM9XE range of processors.  These are
basically AT91SAM9260's with different amounts of internal SRAM and
Flash.

We make use of the existing AT91SAM9260 support, but just perform
run-time detection of the size of the internal SRAM.

Andrew Victor 9d0412680e [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directories
Now that Linux includes support for the Atmel AT91SAM9260 and
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.

The following git commands should be run BEFORE applying this patch:
  git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
  git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91
