[flashrom] [PATCH 3/4] sbxxx: Add support for new AMD SPI controller.

[Wei Hu]

Stefan,

Thanks for your great work. I just tested it on AMD Olive Hill, and
found a few issues.

1. Your patch defaults SPI clock to 16.5 MHz, which didn't work. I
also found none of 22, 33, 100 MHz worked. Only passing -p
internal:spispeed="66 MHz" worked.

2. Reading is much faster than my/Carl's patch, but some bits were
incorrect. The speedup must have come from your use of the now longer
FIFO, but why is it reading bad values?
