I'm running this on a Coldfire (MCF5484) processor for Linux 2.6.25. I've
got 64MB of Intel P33 flash. I have two chips that have their chip selects
tied together to give me 32 bit read/write.

flinfo shows:

Bank # 1: CFI conformant FLASH (32 x 16)  Size: 64 MB in 259 SectorsEC0000
  Intel Extended command set, Manufacturer ID: 0x89, Device ID: 0x22
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 2 ms, buffer size: 64 bytes
addr_first:     0xfc002000

  FC300000        FC340000        FC380000        FC3C0000        FC400000
etc....


Got CS0 set as:

#define CFG_CS0_BASE            0xFC000000
#define CFG_CS0_MASK            (((CFG_BOOTSZ << 20) - 1) & 0xFFFF0001)
#define CFG_CS0_CTRL            0x00002500


This chips first four sectors are 32K (the rest are 128K). The
CFG_ENV_SECT_SIZE is set to 0x2000. However if I change it to 32K I get
errors. On top of that the sector boundaries look fine in flinfo. I put in
some debug to see more about the error and I get:

-> save
Saving Environment to Flash...
addr_first:     0xfc002000
info->start[0]: 0xfc000000
b_end:          0xffffffff
Error: start address not on sector boundary

Not sure what to do with this. Any help appreciated.
