MediaTek published their current U-Boot patchset on github: https://github.com/mtk-openwrt/u-boot/commits/mtksoc Import the platform patches from there (`00-mtk-*.patch`), arrange, them nicely, drop no longer needed local patches and rebase on top of U-Boot 2021.04-rc3. Tested and works well on Linksys E8450 (snand-1ddr) as well as Bananapi BPi-R64 (sdmmc-2ddr, emmc-2ddr). Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH 21/21] mmc: mtk-sd: don't ignore max-frequency from device
|
|
tree
|
|
|
|
commit e58e68d9 ("mmc: mtk-sd: assign plat->cfg.f_max with a correct value")
|
|
wrongly assumed that plat->cfg.f_max is always unset at the time
|
|
mscd_drv_probe() is run. This is not true in case max-frequency being
|
|
defined in device tree, as it is then already set by mmc_of_parser()
|
|
in msdc_of_to_plat().
|
|
Only set plat->cfg.f_max to the default maximum value in case it is
|
|
not already set to a sane value.
