Various issues were discovered in getting Chromium OS verified boot running on top of coreboot, booting into U-Boot.
Improvements include: - enable serial console if even coreboot doesn't - enable cache always - show the BIOS date since Chromium OS's coreboot doesn't have a version - update docs - allow SPI driver to work without a PCH - fix mtrr command when multi-processing (CONFIG_MP) is disabled - add documentation about the memory map
Changes in v2: - Add a comment about the cases - Reorder declaration and use bios_date for the variable name - Add missing newline in the error path - Use (ret) instead of (ret != 0) to fit with U-Boot style - Convert table to reST format - Add 'cros' tag since this not a generic x86 change - Drop unnecessary patch 'Enable the cbsysinfo command'
