Hi,
    I turned on LE_BYTE_SWAP as you requested, with similar results:

physmap flash device: 4000000 at 8000000
HKC: output of ioremap: Map Priv 1 = 0xc2003000

CFI: Found no Physically mapped flash device at location zero

I have also tried replacing the ioremap call in init)physmap with
ioremap_nocache() but with no byte swapping. Should I try it with
LE_BYTE_SWAP?
