arm: mediatek: mt8512: fix gd->bd->bi_dram[0].size

2026-06-24T15:06:16Z

Use board_get_usable_ram_top() instead of get_effective_memsize() to limit gd->ram_top. 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 b9e6281632a8 ("arm: mediatek: mt8512: drop dram_init_banksize()"), gd->bd->bi_dram[0].size was overridden in a board-specific dram_init_banksize() implementation. We can just use board_get_usable_ram_top() now to set gd->ram_top to the correct value instead. Overriding gd->bd->bi_dram[0].size was a bit confusing since it isn't easily apparent which order the functions that set it are called.

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.
