arm: mediatek: add SIP platform bininfo lookups

2026-04-07T18:14:29+00:00

Add a couple of functions to look up the segment and part name using SIP
calls. These will be used to print more accurate CPU information in
print_cpuinfo().

arm: mediatek: mt8518: remove call to fdtdec_setup_memory_banksize()

2026-04-06T23:39:11+00:00

Remove an incorrect call to fdtdec_setup_memory_banksize() in
dram_init() for mt8518.

fdtdec_setup_memory_banksize() populates gd->bd->bi_dram[bank].start
and gd->bd->bi_dram[bank].size base on the "memory" node in the device
tree. However, calling it from dram_init() is too early because gd->bd
has not been allocated yet.

gd->bd->bi_dram[0].start and gd->bd->bi_dram[0].size are already
correctly initialized later in dram_init_banksize(), so we do not need
to replace the removed function call with anything else.

arm: mediatek: mt8195: fix gd->ram_top limit

2026-04-06T23:39:10+00:00

Fix the implementation of the gd->ram_top limit for mt8195.

The intention of the comment about MMC/DMA is correct, but the
implementation was wrong. gd->mon_len is set to the code size of U-Boot,
so trying to set it to limit gd->ram_top does not make sense.

Instead, there is already a get_effective_memsize() weak function that
we can override to implement the required limit on the usable memory
size. This is used to set gd->ram_top in setup_dest_addr().

The comment about the extra SZ_1M needing to be reserved is not correct
as U-Boot already takes care of this (with the actual size of U-Boot) in
the various board_f functions, so it is removed.

This fixes DMA not working on MMC on mt8195.
