[U-Boot] [PATCH v2] Add support for the Calao QIL-A9G20 and QIL-A9260 boards
Albin Tonnerre

Sat Jan 9 19:05:34 CET 2010
The Calao QIL-A9G20 and QIL-A9260 boards are manufactured and sold by
Calao Systems <http://www.calao-systems.com>. They are respectively
built around an AT91SAM9G20 ARM SoC running at 400MHz and an AT91SAM9260
SoC running at 200MHz. They feature an Ethernet port, an SPI RTC backed
by an onboard battery, an SD/MMC slot, a CompactFlash slot, 64Mo of
SDRAM, 256Mo of NAND flash, two USB host ports, and an USB device port.
More information can be found at
<http://www.calao-systems.com/articles.php?lng=en&pg=5936>

Changes in v2:
- Remove QIL_A9xxx_EEPROM_config targets, as putting the env in EEPROM doesn't work currently
- Fix inconsistencies between Makefile, MAINTAINERS and the commit message
- use a #define in the config file to define the correct MACH_TYPE according to the CPU
- remove uses of CONFIG_RESET_PHY_R
- Fix some lines that were too long
- don't #undef CONFIG_CMD_{BDI,IMI,LOADS,SOURCE}
