In practice it doesn't matter much, because you wouldn't do that for a real-life system, but out of principle this seems like something you'd better put into the defconfig file for both ARCH_EFM32 and ARCH_STM32. We could also think about changing the default to "9" for any ARM_SINGLE_ARMV7M config and increasing it again in defconfig for any platform that actually has a lot of RAM (if any). The SOC_AM33XX is slightly different because it increases the default rather than reducing it, presumably because the larger allocation is actually required (for what?).
