From: Apurva Nandan <[email protected]> Add Kconfig options to enable SPL loading of U-Boot from MTD devices:
- SPL_MTD_LOAD: Enable loading via MTD framework - SYS_MTD_U_BOOT_OFFS: Configure U-Boot offset in MTD flash (default 0x80000 for K3, 0x0 otherwise) This provides a unified boot path for all MTD devices.
