mb/purism/librem_l1um_v2: Add support for Purism Librem L1UM v2
This adds support for booting the Librem L1UM v2 mainboard with coreboot, using binaries from the original BIOS. The following features have been tested on PureOS: - USB: front USB3, rear USB3, USB2 header on board - SATA: 8x SATA ports, one M.2 M-key shared with SATA0 - PCIe: two PEG slots, one PCIe slot from PCH, and one M.2 M-key - Network: 2x GbE - Video: BMC VGA and IPMI - Serial: Physical serial port, provided by BMC SuperIO - Hardware monitor - POST code display - TPM2 These binaries are extracted from the original BIOS: - Intel Management Engine - Intel Firmware Descriptor This was developed and tested on a Librem L1UM v2 using a Core i7-9700 CPU. Native graphics init works for the Aspeed AST2500 BMC. For development, the serial port console works from bootblock. Early init waits for the BMC to finish booting since this is required for serial port output.
