The value of ram_top address currently gets computed in an indirect manner. The boot_fdt_add_mem_rsv_regions() function gets called first to reserve the memory region occupied by OP-TEE in the LMB memory map. This is followed by a call to the lmb_alloc() API, which returns an address which is below the OP-TEE base address. This address is the value of ram_top returned by the board_get_usable_ram_top() function. This has now changed, as the LMB memory map, which is no longer local, gets set up after relocation. Get the OP-TEE base address by reading the device tree, and set the ram_top from this value. Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org>
