mb/purism/librem_whl: Add new board Librem Mini (WHL-U)
Add new librem_whl baseboard and Librem Mini variant. Tested with SeaBIOS, Tianocore, and Heads payloads. All functions working normally except SATA, which is limited via a FSP UPD to 3Gbps until the correct HSIO PHY settings can be determined. https://puri.sm/products/librem-mini/ Signed-off-by: Matt DeVillier <matt.devillier@puri.sm> Change-Id: I36af42766f85eb17f86f6ec9b48b87125fb911e6 Reviewed-on: https://review.coreboot.org/c/coreboot/+/40278 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
