Describes the size of MCU Scratchpad RAM.These are very generic names. And are these really things that can be configured and changed by the user? MAX_DOWNLODABLE_IMAGE_SIZE is
You are right. These are not configurable by user, but changes from SoC to SoC within K3 family. Will fix it in v2 by dropping the prompt string.
Thanks and regards, Lokesh
something we usually set in CONFIG_SPL_MAX_SIZE but I imagine the overall architecture means that perhaps that's not the exact variable we're talking about here.
