Change subject: google/kukui: Load calibration params and run DRAM calibration flow ......................................................................

google/kukui: Load calibration params and run DRAM calibration flow

Load the calibration params from flash first and check the correctness of the params. If the params have correct format, perform DRAM fast calibration with these params to reduce bootup time. Otherwise, load the DRAM blob and perform DRAM full calibration.

We probably want to give more reason telling user why we choose re-calibrating data. […]

How about using 'BIOS_NOTICE'? I don't think missing flash data is an error.

@hungte Should we move the changes in this file to soc/mediatek/mt8183/Makefile. […]

That may be a good idea. In the meantime I think we should make it a Kconfig. Would be best if in the end we can override it from configs so chrome os local builds can use files from local repo. Maybe config

MT8183_DRAM_FULLK_BLOB default "3rdparty/blobs/soc/mediatek/mt8183/dram.elf"

@hungte Should we also put get_sdram_config() into dramc_param_ops?

sounds like a good idea.

we may even put the CONFIG_EMCP thing into a function like

.get_config

https://review.coreboot.org/c/coreboot/+/35110/47/src/mainboard/google/kukui... File src/mainboard/google/kukui/Makefile.inc:

https://review.coreboot.org/c/coreboot/+/35110/47/src/mainboard/google/kukui... PS47, Line 35: DRAM_CBFS := $(CONFIG_CBFS_PREFIX)/dram

...

That may be a good idea. In the meantime I think we should make it a Kconfig. […]

Let's add the config in another CL.

https://review.coreboot.org/c/coreboot/+/35110/47/src/mainboard/google/kukui... File src/mainboard/google/kukui/romstage.c:

https://review.coreboot.org/c/coreboot/+/35110/47/src/mainboard/google/kukui... PS47, Line 44: assert(length <= CALIBRATION_REGION_SIZE);

...

Can we replace this with Static_assert?

Change subject: soc/mediatek/mt8183: Run DRAM full calibration ......................................................................

soc/mediatek/mt8183: Run DRAM full calibration

Bootup time of DRAM partial calibration: - 1,349,385 usecs with low frequency - 924,698 usecs with middle frequency - 1,270,089 usecs with high frequency 3,544,172 usecs in total.

Bootup time of DRAM fast calibration: - 216,663 usecs with low frequency - 328,220 usecs with middle frequency - 322,612 usecs with high frequency 867,495 usecs in total.
