This patch adds a new utility for converting a pad configuration from the inteltool dump to the PAD_CFG_*() macros [1] for coreboot and GPIO config data structures for FSP/sdk2-platforms/slimbootloader [2,3]. Mirror: https://github.com/maxpoliak/pch-pads-parser.git [1] src/soc/intel/common/block/include/intelblocks/gpio_defs.h [2] https://slimbootloader.github.io/tools/index.html#gpio-tool [3] 3rdparty/fsp/CometLakeFspBinPkg/CometLake1/Include/GpioSampleDef.h Change-Id: If3e3b523c4f63dc2f91e9ccd16934e3a1b6e21fa Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/35643 Reviewed-by: Andrey Petrov <andrey.petrov@gmail.com> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
