arm: mediatek: mt7988: fix gd->bd->bi_dram[0].size

2026-06-24T15:06:16Z

Use board_get_usable_ram_top() instead of get_effective_memsize() to set gd->ram_top to something <= 4GiB. Both board_get_usable_ram_top() and get_effective_memsize() are used to set gd->ram_top in setup_dest_addr(). However, get_effective_memsize() also sets gd->bd->bi_dram[0].size in dram_init_banksize(), which is undesirable. Prior to commit bddd6bbef3dc ("arm: mediatek: mt7988: drop dram_init_banksize()"), gd->bd->bi_dram[0].size was overridden in a board-specific dram_init_banksize() implementation. When that was removed get_effective_memsize() set gd->bd->bi_dram[0].size to the wrong value because of CFG_MAX_MEM_MAPPED. Rather than continue to use an old-style CFG_ option and the potentially confusing overriding of gd->bd->bi_dram[0].size (it is difficult to see which order the functions that set it are called), we can just use board_get_usable_ram_top() to set gd->ram_top to the correct value instead. This is possible now, thanks to LMB_LIMIT_DMA_BELOW_RAM_TOP being set by default for 64-bit Mediatek ARM SoCs. The CFG_MAX_MEM_MAPPED option is removed since it is no longer needed. The config header and Kconfig option are also removed since that was the last CFG_ option.

This is possible now, thanks to LMB_LIMIT_DMA_BELOW_RAM_TOP being set by default for 64-bit Mediatek ARM SoCs. On mt7987, there is already an implementation of board_get_usable_ram_top() for other reasons, so it is modified to also limit ram_top to 4GiB (mt7987 is currently the only thing that sets CONFIG_MTK_TZ_MOVABLE=y so it is safe to change this here without unintentional side-effects). The CFG_MAX_MEM_MAPPED option is removed since it is no longer needed. The config header and Kconfig option are also removed since that was the last CFG_ option.

config: mediatek: add UFS defconfigs for Genio 520/720 EVKs

2026-04-17T22:05:54Z

Add variants of the Genio 520/720 EVK defconfigs for UFS boot. These have a different devicetree when the boot DIP switches/jumpers on the EVK are set for UFS instead of eMMC. These also enable UFS and related drivers that aren't enabled in the eMMC defconfigs since UFS is disconnected in that case.

arm: dts: mediatek: add UFS variant of Genio 520/720 EVK

2026-04-17T22:05:54Z

Add a devicetree overlay and UFS variants of the Genio 520 and Genio 720 EVK devicetree targets. There are dip switches and jumpers on the EVK that disconnect the eMMC and connect the UFS instead. The overlay adjusts the devicetree for this. Reviewed-by: Macpaul Lin Link: https://patch.msgid.link/20260330-mtk-genio-720-ufs-v1-5-3bad8362ed70@baylibre.com Signed-off-by: David Lechner

This new defconfig is based on mt8395_genio_1200_evk_defconfig, with additional configs for UFS. In order to avoid duplicating defconfig, we introduce configs/mt8195.config.

arm: dts: add U-Boot overrides for Genio 520 and 720 SD card

2026-04-07T16:07:44Z

Add U-Boot-specific device tree overrides for the Genio 520 and 720 EVK boards. These are needed to enable SD card support in U-Boot due to current driver limitations. It is expected that these files will remain after eventually converting these to CONFIG_OF_UPSTREAM, so we use separate .u-boot.dtsi files for this.
