Ummmm. Maybe I was wrong, as I was thinking that CFI was also
part of the JEDEC standards.
Nevertheless, in datasheet from Spansion I can read:

CFI (Common Flash Interface) compliant

So this should not be the issue here.

Neither the command address I have reported before.
A deeper analyse of driver showed me that address is shifted
in write cfi_write_cmd. Indeed command to query CFI Table (0x98)
works. So, maybe problem is Program command AMD_CMD_WRITE, which
is not present in 8bit mode.
