2020-10-23mb/google/dedede: Update the flash ROM layout for RW regionsKarthikeyan Ramasubramanian
RW_LEGACY region needs to be 1 MiB to accommodate any alternate firmware. Hence update the flash ROM layout as below: * Grab ~512 KiB from each FW_MAIN_A/B regions and allocate them to RW_LEGACY region so that it grows to 1 MiB. * Remove VBLOCK_DEV region which is not used. * Re-size the ELOG region to 4 KiB since that is the maximum size of the ELOG mirror buffer. * Resize RW_NVRAM, VBLOCK_A/B regions to 8 KiB since no more than that size is used in those regions. * Resize SHARED_DATA region to 4 KiB since no more than that size is used in that region. * Based on the resizing, allocate each FW_MAIN_A/B regions with 72 KiB. BUG=b:167943992, b:167498108 TEST=Build and boot to OS in Drawlat. Ensure that the firmware test setup and flash map test are successful. Ensure that the event logs are synced properly between reboots. Ensure that the suspend/resume sequence is working fine. Ensure that the ChromeOS firmware update completes successfully for the boot image with updated flash map and the system boots fine after the update.

2020-06-18mb/google/dedede: Add support for 16 MiB flash map descriptorKarthikeyan Ramasubramanian
Upcoming variant boards will use 16 MiB SPI ROM. So add support for 16 MiB flash map descriptor. BUG=b:155107866,b:152981693 TEST=Build different variant boards. Ensure that waddledoo which is using 32 MiB SPI ROM boots.
