v3 2nd run boards (aka v2 FIX)¶

S25FL127SABMFV000
EPCS128 compatible?
Read silicon id (0xab) gives TODO
Read device id (0x9f) gives TODO (first 3 bytes count)
Sector size? Seems to wipe core with 64KB, but seems to run well with 256KB? Need to check status register... Has some fancy hybrid sector 4K/64K thing.
