From 630aa4b3db1b7fa459380ec52328d632b53b22de Mon Sep 17 00:00:00 2001 From: Aamir Bohra Date: Fri, 6 Dec 2019 19:19:19 +0530 Subject: mb/intel/jasperlake_rvp: Add initial mainboard code This is a initial mainboard code aimed to serve as base for further mainboard check-ins. This is a copy patch from icelake_rvp as on commit ID: I64db2460115f5fb35ca197b83440f8ee47470761 Below are the changes done over the copy patch: 1. Rename "Icelake" with "Jasperlake". 2. Replace "icelake_rvp" with "jasperlake_rvp". 3. Rename "icl" with "jsl". 4. Remove unwanted SPD file, add empty SPD as placeholder. 5. Replace "soc/intel/icelake" with "soc/intel/tigerlake" as tigerlake SOC hosts jasperlake code as well. 6. Empty romstage_fsp_params.c, to fill it later with SOC specific config. 7. Empty GPIO configuration, to be filled as per board. 8. Change copyright year to 2019. 9. Add two board support namely BOARD_INTEL_JASPERLAKE_RVP and BOARD_INTEL_JASPERLAKE_RVP_EXT_EC 10. Replace icl_u and icl_y variant with jslrvp variant. 11. Remove basebord gpio.c and rely on variant override. 12. Remove HDA verb table and config support. Changes to follow on top of this: 1. Add correct memory parameters, add SPDs. 2. Clean up devicetree as per jasperlake SOC. 3. Add GPIO support. 4. Update chromeos.fmd to make 10MB BIOS region.
