2021-04-26soc/intel/elkhartlake: Update GPIO communitiesTan, Lean Sheng
GPIOs are divided into different communities. Each community consists of one or more GPIO groups. We need to configure the groups in coreboot so that they are mapped properly. GPIO communities should be properly configured in GPIO_CFG and MISCCFG registers. GPP_* defines in gpio_soc_defs.h are configured in GPIO_CFG register while the PMC_GPP_* in pmc.h. GPIO communities in coreboot should match with the kernel gpio communities also. Kernel reads the ASL file from coreboot. This patch adds the proper community mapping in ASL code to match with kernel code. In gpio_soc_defs.c file we are indexing the groups correctly. In gpio.h file we define all the gpio devices as kernel populates sysfs with separate gpio device for each community. This patch is created based on Intel EHL PCH Datasheet with Document number 614109 and Chapter 21. Also update GPIO COM3 Port ID and 2 GPIO register values (HOSTSW_OWN_REG_0 & PAD_CFG_BASE) respectively.

2020-09-08soc/intel/elkhartlake: Do initial SoC commit till ramstageTan, Lean Sheng
Clone entirely from Jasperlake List of changes on top off initial jasperlake clone 1. Replace "Jasperlake" with "Elkhartlake" 2. Replace "jsl" with "ehl" 3. Replace "jsp" with "mcc" 4. Rename structure based on Jasperlake with Elkhartlake 5. Clean up upd override in fsp_params.c will be added later 6. Sort #include files alphabetically as per comment 7. Remove doc details from espi.c until it is ready 8. Remove pch_isclk & camera clocks related codes 9. Add new #define NMI_STS_CNT & NMI_EN as per comment Signed-off-by: Tan, Lean Sheng <lean.sheng.tan@intel.com> Change-Id: I372b0bb5912e013445ed8df7c58d0a9ee9a7cf35 Reviewed-on: https://review.coreboot.org/c/coreboot/+/44802 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Werner Zeh <werner.zeh@siemens.com>
