Hi there,
I have troubles with current AMD & Fujitsu CFI driver. When it works
with 2 x16 devices in 32-bit mode, it fails to correctly detect ending
of erasure operation. Looks like that when one device reports the end of
operation by setting all 16 its bits in 1, the other device is not done
yet, and the code in chip_status() returns CHIP_TIMEDOUT because it
doesn't consider such a situation.
I wonder if there's a fix for this issue already or anybody's gonna
fix it soon.
wbr, Dmitry

That's correct. chip_status() is broken for interleaved chips. Which is
why the latest version (1.98) in CVS no longer uses it. Update and see
if that fixes the issue.
