Enable VBOOT support on all devices that have a 12 MiB flash, using RW_MAIN_A + RW_MAIN_B partition, allowing the use of tianocore payload in both RW_MAIN_A, RW_MAIN_B and WP_RO. * Add VBNV section to cmos.layout * Add FMAP for VBOOT * Select Kconfigs for VBOOT * Enable VBOOT_SLOTS_RW_AB by default The VBNV is intentionally not covered by the CMOS checksum.

2020-02-09mb/lenovo/t440p: Enable dGPU on Lenovo T440PChris Morgan
Enable the dGPU on the Lenovo T440P. It uses the same code (roughly) of the T430S. By default, it is set to be disabled however it can be enabled via the nvram option enable_dual_graphics. Removed hybrid graphics options too as they are not valid for the T440p. Tested on a T440P with Ubuntu 18.04.4 with Kernel 5.3.0-29 (successful). Tested on same machine with Windows 10 1909 (machine check exception bluescreen).

2020-02-03lenovo/t440p: fix keyboard backlightIru Cai
It is found that keyboard backlight in T440p is enabled by clearing bit 3 of EC RAM 0x01. This patch sets has_keyboard_backlight in devicetree.cb and also corrects the CMOS configuration.
