mb/intel/adlrvp_n: Add initial code for adl-n variant board
This patch adds the following list of changes: 1. Create a new devicetree for adlrvp-n and copy contents of adlrvp-p devictree. 2. Add support for 2 mainboards as ADL-N board with default EC (Windows SKU) and Chrome EC (Chrome SKU) and copy overridetree contents from adlrvp-p. 3. Add mainboard Kconfig to Kconfig.name file 4. Handle mainboard names in Kconfig file for ADLRVP N 5. Add config options to pick the adlrvp_n devicetree Change-Id: I4abf3bf62ec0398ae75e21575a2fab0d44b5c7ad Signed-off-by: Usha P <usha.p@intel.com> Signed-off-by: Krishna Prasad Bhat <krishna.p.bhat.d@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/59915 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
