Unfortunately this breaks CFI support for "normal" AMD/Spansion FLASH equipped 
boards. On Sequoia with Spansion GL512 I get this after applying your patch:

U-Boot 1.3.2-01356-g8fa1348 (Apr 24 2008 - 17:05:55)

CPU:   AMCC PowerPC 440EPx Rev. A at 528 MHz (PLB=132, OPB=66, EBC=66 MHz)
       Security/Kasumi support
       Bootstrap Option H - Boot ROM Location I2C (Addr 0x52)
       Internal PCI arbiter enabled, PCI async ext clock used
       32 kB I-Cache 32 kB D-Cache
Board: Sequoia - AMCC PPC440EPx Evaluation Board, Rev. F, PCI=66 MHz
I2C:   ready
DTT:   1 is 29 C
DRAM:  256 MB
FLASH: CFI: Unknown command set 0x0
*** failed ***
### ERROR ### Please RESET the board ###

:-(

Please fix this and resubmit. Best would be if you could test it on a board 
with Spansion CFI FLASH's too.

Thanks.

Best regards,
Stefan
