You are right! I must have deleted too much from the diff... I should
not do so many changes on one source tree.

I've prepared a patch for r3129 WITH the definition of the static
function..

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.
