* modules/linux: Add support for multiple kernel versions Follow same pattern as used for coreboot. Add existing kernel version as default for all existing boards. Signed-off-by: Matt DeVillier <matt.devillier@puri.sm> * modules/linux: Add option to use 4.19 LTS kernel Add option to use kernel 4.19.139 (current LTS version). Duplicate existing patches from 4.14.62 as they all apply cleanly. Signed-off-by: Matt DeVillier <matt.devillier@puri.sm>
