2020-12-14soc/intel/common: Move CSE Lite driver functionality into romstageSridhar Siricilla
The patch sets up the CSE Lite driver in the romstage instead of ramstage. With this change, CSE Lite driver sets CSE's boot partition and triggers CSE FW update in the romstage. The cse_fw_sync() must be called after DRAM initialization as HMRFPO_ENABLE HECI command (which is used by cse_fw_sync()) is expected to be executed after DRAM initialization. With this change, it improves the cold boot time by ~154ms.

This change drops the special check added for TGL/JSL platforms and performs cse_fw_sync on BS_PRE_DEVICE entry. This was being done later in the boot process to ensure that the memory training parameters are written back to SPI flash before performing a reset for CSE RW jump. With the recent changes in CB:44196 ("mrc_cache: Update mrc_cache data in romstage"), MRC cache is updated right away in romstage. So, CSE RW jump can be performed in BS_PRE_DEVICE phase.

2020-11-18soc/intel/common: Move CSE RW into new FMAP region to optimize boot timeSridhar Siricilla
CSE RW blob which will be used by coreboot to update CSE's RW partition, is packed part of FW_MAIN_A and FW_MAIN_B. This will increase the size of FW_MAIN_A and FW_MAIN_B. So, accordingly load and hash calculation of FW_MAIN_A (or FW_MAIN_B) increases during verstage. It increases the boot time by around 300ms. The patch address the boot time by pulling CSE RW blob outside of FW_MAIN_A and FW_MAIN_B. So, it creates new FMAP region within RW_SECTION_A and RW_SECTION_B and adds CSE RW blob in the new regions (ME_RW_A and ME_RW_B) as a CBFS file.

2020-08-20cse_lite: Move global reset after MRC writebackCaveh Jalali
With CSE-lite enabled, we were going through the lengthy memory training procedure twice on the first power-on boot or after full BIOS SPI flash update. This moves the global reset performed to achieve the CSE-lite RO to RW reboot to a later boot phase so that it happens after the memory training data has been written to the MRC cache. Now, the 2nd (and subsequent) reboot can utilize the memory training data established during the 1st boot. This reduces the first boot time by about 20s on a 16GB system. Looking at the timing stats form cbmem, the normal boot penalty is about 300ms - mostly attributed to running FspSiliconInit a 2nd time. We will get this time back when the mrc_cache refactoring effort lands (cb:44196, et. al). BUG=b:162021048 TEST=Booted on volteer, confirmed 20s faster boot time.
