From: Dinesh Maniyam <[email protected]> The SPL NAND MTD framework requires working driver model support and sufficient memory resources, which are not available on all platforms.
Introduce a SPL_NAND_FRAMEWORK_CAPABLE Kconfig option to allow platforms to explicitly advertise support for compiling the full NAND/MTD framework into SPL. This avoids accidental enablement of the SPL NAND framework on platforms that cannot support it and provides a clear capability boundary for platform maintainers.
