Hello,
SPI flash chip Sanyo LE25FU406B works (after a small patch) with flashrom.
It is very similar to Sanyo LE25FW418A, except for HD_READ support (that
is not implemented in flashrom anyway) and voltage range.
Probing, erasing, reading and writing works (after patch).
This chip is found on Seagate Constellation hard drives...
