[PATCH] Add chips Winbond W39F010/L010/L020 - flashrom

11 Oct 2012

W39F010 is 128kB parallel 5V flash chip, 16k bootblocks.
W39L010 is 128kB parallel 3V flash chip, 8k bootblocks.
W39L020 is 256kB parallel 3V flash chip, 64k/16k bootblocks.
Considering the test of W39F010, on the platform [1] the first write
attempt after erase returned with verify failure. Second write attempt
and following read-verify was succesful.
[1] "Silicon Image SiI 3124 PCI-X SATA Ctrl" (1095:3124, BDF 07:04.0).
