2020-03-06soc/mediatek/mt8183: Correct EMI bandwidth threshold for DVFS switchHuayang Duan
Because eMCP and discrete DDR devices have different DVFS tables, their EMI bandwidth thresholds should also be different. When the EMI total bandwidth reaches the threshold, the system will notify DVFS module to perform DVFS switch for system performance in low power states. This patch increases the threshold from 0xa to 0xd for eMCP DDR devices so that DVFS switch will be less likely to happen. The register table of EMI_BWCT0 is incorrect in the datasheet. According to the hardware design, BW_2ND_INT_BW_THR should be in bits [30:24] instead of [22:16]. However, the logic in DRAM driver is correct, aligned with the hardware design, so we don't need to correct it.

2020-02-17soc/mediatek: dsi: reduce the hbp and hfp for phy timingJitao Shi
The extra data transfer in DSI, namely, lpx, hs_prepare, hs_zero, hs_exit and the sof/eof of DSI packets, will enlarge the line time, which causes the real frame on dsi bus to be lower than the one calculated by video timing. Therefore, hfp_byte is reduced by d_phy to compensate the increase in time by the extra data transfer. However, if hfp_byte is not large enough, the hsync period will be increased on DSI data, leading to display scrolling in firmware screen. To avoid this situation, this patch changes the DSI Tx driver to reduce both hfp_byte and hbp_byte, with the amount proportional to hfp and hbp, respectively. Refer to kernel's change in CL:1915442. Also rename 'phy_timing' to 'timing' to sync with kernel upstream. Since the phy timing initialization sequence has been corrected, the m value adjustment in the analogix driver can be removed.

2019-11-14lib/fmap: Add optional pre-RAM cacheJulius Werner
This patch adds an optional pre-RAM cache for the FMAP which most platforms should be able to use, complementing the recently added post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP about half a dozen times from flash in verstage, which will all be coalesced into a single read with this patch. It will also help future vboot improvements since when FMAP reads become "free" vboot doesn't need to keep track of so much information separately. In order to make sure we have a single, well-defined point where the new cache is first initialized, eliminate the build-time hardcoding of the CBFS section offsets, so that all CBFS accesses explicitly read the FMAP. Add FMAP_CACHEs to all platforms that can afford it (other than the RISC-V things where I have no idea how they work), trying to take the space from things that look like they were oversized anyway (pre-RAM consoles and CBFS caches).

SoC DRAM team suggested always running full calibration mode in recovery mode because it is possible to get unstable memory even if the complex memory test has been passed. Since the recovery mode runs from RO and we only have training data cache for RW, the trained calibration data can't be saved since RO and RW may be running different firmware. Also revised few message to make it more clear for what calibration mode (fast, full, or partial) has been executed.

They also made header changes that now allow us to directly include all the headers we need (in a safer and cleaner way than before), so we can get rid of some structure definitions that were duplicated. Since the version of entry point info parameters we have been using has been deprecated in Trusted Firmware, this patch switches to the new version 2 parameter format.
