[PATCH 1/5] ARM: nommu: drop support for ARM740T, ARM940T and ARM946E-S processors

Uwe Kleine-König u.kleine-koenig at pengutronix.de
Thu Jun 5 02:06:09 PDT 2014


There are no symbols selecting the corresponding processor symbols
(CPU_ARM740T, CPU_ARM940, CPU_ARM946E) and they are only user selectable
with ARCH_INTEGRATOR. But as the processor symbols depend on !MMU and
ARCH_INTEGRATOR selects ARM_PATCH_PHYS_VIRT which depends on MMU these
configurations are broken since at least Linux 3.13.

As a side effect this patch removes most usages of CONFIG_DRAM_SIZE.
