Reference: http://plugcomputer.org/ http://openplug.org/plugwiki/index.php/Das_U-boot_plug_support
This patch is tested for- 1. Boot from DRAM/NAND flash 2. File transfer using tftp 3. NAND flash read/write/erase 4. Linux kernel and RFS Boot from NAND 5. Enabled USB PHY init for kernel need 6. Boot from USB supported
Note: to boot Kirkwood kernel with USB support, you should add "usb start" in the boot sequence
Signed-off-by: Prafulla Wadaskar prafulla@marvell.com --- Change log: v2: updated as per feedback for v1
v3: updated as per feedback for v2
v4: removed PHY driver dependency, coded in sheevaplug.c
v5: USB support added
v6: config_cmd_default.h used in board config
v7: sheevaplug.h alligned as per cleanup in config_cmd_default.h
