[U-Boot] [PATCH v5 6/6] Marvell Sheevaplug Board support

Prafulla Wadaskar
2009-06-29T15:31:07Z

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
