I don't fully understand the question. The 'len' member of the struct
erase_info contains the total length of the erase requested by the user of
the MTD device. The only connexion with the device's erase size(s) is that
obviously the range to be erase must start and end on an eraseblock
boundary.
cfi_amdstd_erase_varsize() is an internal function intended to issue the
magic erase commands only to a certain address on the chip - it doesn't
know anything about the erase size at that address, or care about the
length field, does it?
