That's because calling iotable_init after bootmem_init will skip
calling arm_bootmem_init and the new memblock_region we never
call reserve_bootmem on the new entry. So let's skip this for now.
If we want to do SoC detection and SRAM init later during the
boot, we'd have to allocate SRAM the same way as dma-mapping
and ioremap code does.
Regards,
Tony
