| |
The ARCH_SELECT_MEMORY_MODEL in arch/arm/Kconfig is enabled only when ARCH_SPARSEMEM_ENABLE=y. But in this case, ARCH_SPARSEMEM_DEFAULT is also enabled and this in turn enables SPARSEMEM_MANUAL.
Since there is no definition of ARCH_FLATMEM_ENABLE in arch/arm/Kconfig, SPARSEMEM_MANUAL is the only enabled memory model, hence the final selection will evaluate to SPARSEMEM=y.
Since ARCH_SPARSEMEM_ENABLE is set to 'y' only by several sub-arch configurations, the default for must sub-arches would be the falback to FLATMEM regardless of ARCH_SELECT_MEMORY_MODEL.
