[U-Boot] [PATCH v2] Marvell MV88F6281GTW_GE Board support

Prafulla Wadaskar prafulla at marvell.com
Wed Apr 8 18:18:11 CEST 2009


From: prafulla_wadaskar <prafulla at marvell.com>

This is Marvell's 88F6281_A0 based custom board developed
for wireless access point product

This patch is tested for-
1. Boot from DRAM/SPI flash/NFS
2. File transfer using tftp and loadb
3. SPI flash read/write/erase
4. Booting Linux kernel and RFS from SPI flash
Note: doImage utility needed to convert u-boot.bin to 
u-boot-spiflash.bin, DRAM configuration will be part of
this utility
