[Qemu-devel] [PATCH v3 08/10] block/pflash_cfi02: Implement multi-sector erase

2019-04-17 Thread Stephen Checkoway
After two unlock cycles and a sector erase command, the AMD flash chips start a 50 us erase time out. Any additional sector erase commands add a sector to be erased and restart the 50 us timeout. During the timeout, status bit DQ3 is cleared. After the time out, DQ3 is asserted during erasure. Sig
