I just noticed I forgot to 'git add' the Kconfig change adding 'select
GENERIC_ALLOCATOR' for NET_MEDIATEK_SOC... I will include that in v4 and
also add a patch dropping the open coded static partitioning of the SRAM
in favor of always using the gen_pool allocator even with legacy device
trees.

Meanwhile I would still be thankful to see this patch reviewed as apart
from the Kconfig addition it won't change.
