7c966a8bdf ARM change name of defines for AT91 arm926ejs
Configuration defines should be preceeded with CONFIG_SYS_. Renamed
some at91 specific defines to conform to this naming convention:

AT91_CPU_NAME to CONFIG_SYS_AT91_CPU_NAME
AT91_MAIN_CLOCK to CONFIG_SYS_AT91_MAIN_CLOCK

425de62d40 add new CONFIG_AT91_LEGACY
* add's the new temporary CONFIG_AT91_LEGACY to all board configs
 This will need for backward compatiblity, while change the SoC access
 to c structures. If CONFIG_AT91_LEGACY is defined, the deprecated
 SoC is used.

4b142febff common: delete CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL
There is more and more usage of printing 64bit values,
so enable this feature generally, and delete the
CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL
defines.

918319c705 Update the mtd driver name in bootargs for at91-based boards
The name of the atmel nand driver in the kernel changed from at91_nand
to atmel_nand back in June 2008, but the at91-based boards config files
still refer to at91_nand. This patch updates them with the new name

2eb99ca802 NAND: Part 2: Fix warning Please define CONFIG_SYS_64BIT_VSPRINTF...
Commit 8d2effea added a warning for configurations that use NAND
without defining the (then necessary) CONFIG_SYS_64BIT_VSPRINTF but
failed to fix the affected boards.

This patch covers the non-PPC boards that were missed in the previous
patch (commit 170c1972).

74de7aefd7 Add "source" command; prepare removal of "autoscr" command
According to the doc/feature-removal-schedule.txt, the "autoscr"
command will be replaced by the "source" command in approximately 6
months from now.

This patch prepares this change and starts a 6 month transition
period as follows:

- The new "source" command has been added, which implements exactly
  the same functionlaity as the old "autoscr" command before
- The old "autoscr" command name is kept as an alias for compatibility
- Command sequences, script files atc. have been adapted to use the
  new "source" command
- Related environment variables ("autoscript", "autoscript_uname")
  have *not* been adapted yet; these will be renamed resp. removed in
  a separate patch when the support for the "autoscr" command get's
  finally dropped.

df486b1fa3 at91: Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.
AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed.

The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board.
It is essentially the same, with a few minor differences.

6c869637fe NAND: rename NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS
This patch renames NAND_MAX_CHIPS to CONFIG_SYS_NAND_MAX_CHIPS and
changes the default from 8 to 1 for the legacy and the new MTD
NAND layer. This allows to remove all NAND_MAX_CHIPS definitions
in the board config files because none of the boards use multi
chip support (NAND_MAX_CHIPS > 1) so far. The bamboo and the DU440
define

 #define NAND_MAX_CHIPS          CONFIG_SYS_MAX_NAND_DEVICE

but that's bogus and did not work anyhow.

3e0cda071a AT91: Enable PLLB for USB
At least some (old ?) versions of the AT91Bootstrap do not set up the
PLLB correctly to 48 MHz in order to make USB host function correctly.

This patch sets up the PLLB to the same values Linux uses, and makes USB
work ok on the following CPUs:
	- AT91CAP9
	- AT91SAM9260
	- AT91SAM9263

This patch also defines CONFIG_USB_STORAGE and CONFIG_CMD_FAT for all
the relevant AT91CAP9/AT91SAM9 atmel boards.
