Hi,

I've ported u-boot to my PXA270 board and have it working as a network 
boot loader.  I'm now trying to get flash programming working so I can 
flash the kernel and root file system.  Our board has two Intel 512Mib 
P30 flashes on it configured as 32-bit memory.  The 512Mib parts are 
actually two 256Mib parts on the same die so u-boot should see two banks 
of 32-bit memory with two flash devices in each bank.

After booting flinfo shows that u-boot has found four devices but the 
addresses seem to be wrong.  It has

bank 1 0x00000000 - 0x03ffffff
bank 2 0x04000000 - 0x07ffffff
bank3 0x00000000 - 0x03ffffff
bank 4 0x00000000 - 0x03ffffff.

Any ideas where I might have gone wrong?  The relevant portions of my 
board header file are below.

Regards,
Justin.
