i get this error on and off from cmd_0001 driver:

TMCU Flash Map Info: buffer write error (status 0xd0)

I looked into the current driver and found something that might a SW bug:
All chip status  looks like this:
 if (map_word_bitsset(map, status, CMD(0x1a))
but I think it should be:
 if (map_word_bitsset(map, status, CMD(0x80)) && map_word_bitsset(map, status, CMD(0x1a)))

because the Intel P30 specs says if the other status bits
is only valid iff bit 7 is also set.

Comments?
