PATCH v5 1/5 lib: fdtdec: Update ram_base to store ram start adddress

From: Siva Durga Prasad Paladugu <[email protected]>

This patch updates the ram_base to store the start address of the first bank DRAM and the use this ram_base to calculate ram_top properly. This patch fixes the erroneous calculation of ram_top incase of non zero ram start address.

PATCH v5 2/5 lib: fdtdec: Rename routine fdtdec_setup_memory_size()

In reply to Michal Simek

From: Siva Durga Prasad Paladugu <[email protected]>

This patch renames the routine fdtdec_setup_memory_size() to fdtdec_setup_mem_size_base() as it now fills the mem base as well along with size.
