Re: [PATCH u-boot-mvebu 1/3] arm: mvebu: a37xx: Fix calling build_mem_map()

Function build_mem_map() modifies global variable mem_map. This variable is used by the get_page_table_size() function which is called by function arm_reserve_mmu() (as aliased macro PGTABLE_SIZE). Function arm_reserve_mmu() is called earlier than enable_caches() which calls build_mem_map(). So arm_reserve_mmu() does not calculate reserved memory correctly.

Fix this issue by calling build_mem_map() from a3700_dram_init() which is called before arm_reserve_mmu().
