2019-10-17soc/mediatek/mt8183: Refactor DRAM init by bit fields APIHung-Te Lin
Replace the magic clrsetbits_le32, read32, write32 by SET_BITFIELDS and other bit field helpers.

2019-10-17soc/mediatek/mt8183: Improve code formattingYu-Ping Wu
This patch contains some minor changes including: - Use lowercase hex literals - Combine short lines - Remove unnecessary curly braces - Simplify struct initialization - Leverage macro _SELPH_DQS_BITS - Ensure whitespaces around binary operators - Remove extra whitespaces after commas - Change log level and remove unnecessary debug logs BUG=none BRANCH=kukui TEST=emerge-kukui coreboot Change-Id: I33616e6142325920c2fd7e6dc1dc88eb29c5cf34 Signed-off-by: Yu-Ping Wu <yupingso@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/36011 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Hung-Te Lin <hungte@chromium.org>
2019-10-09soc/mediatek/mt8183: Use cached calibration result for faster bootupHuayang Duan
Load calibration params from flash. If the format of the params is correct, use these calibration params for fast calibration to reduce the bootup time. 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.

2019-09-20mediatek/mt8183: Implement the dramc init settingHuayang Duan
This patch implements the dram init setting by replacing the hard-coded init sequence with a series of functions to support calibration for more frequencies. These functions are modified from MediaTek's internal DRAM full calibration source code. BUG=b:80501386 BRANCH=none TEST=1. Kukui boots correctly 2. Stress test (/usr/sbin/memtester 500M) passes on Kukui Change-Id: I756ad37e78cd1384ee0eb97e5e18c5461d73bc7b Signed-off-by: Huayang Duan <huayang.duan@mediatek.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/34988 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Hung-Te Lin <hungte@chromium.org>

2018-10-24mediatek/mt8183: Initialize DRAM with a sequence in constant arrayHuayang Duan
The DRAM init sequence is simply setting some values on register for all DRAM modules, no logic involved; so we can replace it by an array to configure easily. BUG=b:80501386 BRANCH=none TEST=Boots correctly on Kukui, and inits DRAM successfully with related patches.
