[PATCH v2 0/4] x86: Correct SPI memory-mapping query

This little series makes the SPI memory-mapping query work on all current
x86 boards where possible, returning an error code (rather than hanging)
when it fails.

It replaces the previous patch at [1]. Unfortunately it is quite a bit
more complicated.

This fixes booting on link and samus. It also fixes MRC saving on

Changes in v2:
- Fix a 'BFF' typo
- Add new patch to allow use before driver model is active

Simon Glass (4):
  x86: spi: Add a way to access the SPI mapping via registers
  x86: spi: Rewrite logic for obtaining the SPI memory map
  x86: spl: Print the error on SPL failure
  x86: mrccache: Allow use before driver model is active
