Re: [coreboot] SST25VF016B (2MB) flash on m57sli (IT8716F).

[Ronald Hoogenboom]

Finally, now I know it's working (at least the part that I'm patching
here...), here is the patch that uses PIO mode read from SPI rom with
lzma decompression.

This patch allows direct out-of-SPI-flash boot of a Linux kernel. It
circumvents the 512KB limitation in the IT8716f superio of memory
mapping an SPI flash device by using a PIO method for reading the data.
Limitation: no nrv2b support.
Not so nice: hardcoded 0x820 SPI-IO port.

Best regards,
Ronald.
