[PATCH v2 00/19] SeaBIOS as Compatibility Support Module for UEFI/OVMF

[David Woodhouse]

Changes from v1:
 - Make CONFIG_CSM a top-level build target in parallel with COREBOOT/QEMU.
 - More Kconfig cleanup.
 - Add generic find_pmtimer() function to find the pmtimer from ACPI tables.
 - Make Xen and coreboot builds both use find_pmtimer().
 - Merge E820 table one entry at a time instead of wholesale copy.
 - Add pic_save_mask() and pic_restore_mask() functions.
 - Less intrusive size reduction for handle_post().
 - Various other cleanups.
