New Revision: 1840
URL: http://flashrom.org/trac/flashrom/changeset/1840
Log:
Unify non-shifted and shifted JEDEC access.
Some Parallel bus chips have a 16-bit mode and an 8-bit mode. They use
normal JEDEC addresses for 16-bit mode and shifted addresses (by 1 bit)
for 8-bit mode. Some programmers can access them in 16-bit mode, but on
all flashrom-supported programmers so far, we access them in 8-bit mode.
This means we have to shift the addresses but apart from the addresses
we can share the code.
This patch makes this possible by checking the chip's FEATURE_ADDR_SHIFTED
flag in common JEDEC functions and applying the right addresses respectively.
