At present x86 does not use driver model for SPI or LPC (low-pin-count, a bus used to talk to the EC on Chromebooks).
This series: - moves the ICH SPI driver over to driver model - moves the cros_ec LPC driver to driver model - removes non-driver-model cros_ec code (since now I2C, SPI and LPC are converted over) - makes some use of the PCI uclass for x86 init, by no means complete - fixes up the keyboard to work on chromebook_link (previously it would only work when started from coreboot)
