Hi David,
Le 06/02/2026 à 00:51, David Lechner a écrit :
Consolidate all mem_map definitions for MediaTek ARMv8 platforms into a
single file. The size of the DDR and MMIO regions can vary, so Kconfig
options are added to configure them by target.

This should be configurable as well: for now, all supported platforms
have their DDR space starting at 0x40000000, but on MT8196 (which I'm
currently working on) it starts at 0x80000000.
