david, as of rev. 2306, your code is in to enable IDE NAND FLASH. output 
fragment looks like this:

southbridge_enable: dev is 0000dcc0
southbridge_enable: enable_ide_nand_flash is 1
cs5536: enable_ide_nand_flash
MDD_LBAR_FLSH0 was 0x0000000000000000
MDD_LBAR_FLSH0 is 0xfffff00720000000
MDD_PIN_OPT was 0x0000000000000f7d
MDD_LBAR_FLSH0 is 0x0000000000000f7c
MDD_NANDF_DATA was 0x0000000007770777
MDD_NANDF_DATA is 0x0000000001110111
MDD_NADF_CNTL was 0x0000000000000777
MDD_NADF_CNTL is 0x0000000000000111
cs5536: EXIT enable_ide_nand_flash

Is this what you want? The names of the MSR's changed to the AMD names.

FILO still doesn't see and IDE drive -- should it?

I'm trying to get some 1Mbyte parts to test linux in BIOS FLASH. The 
only parts I have are the wrong kind. I need to get 49lf008b I think.
