- // This will link an arm elf for uimage. The definitions needed:
- // * RAMRUN_IMAGE_START: The sram start address, including uimage header.
- // * RAMRUN_IMAGE_SIZE: The sram size.
- // * RAMRUN_FLASH_SIZE: The maximum romable size. When defined, it is only
- // used to check romable size.
- // * RAMRUN_MMU_ENABLE: 1 for MMU enabled, 0 for disabled
- // * CONFIG_UIMAGE_HEADER_SIZE: uimage header size.
- //
- // Address between [__flash_start, __flash_end] is romable.
