From ed59e58786cae9f8afcb575649afc65985beed4d Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Mon, 28 Mar 2011 09:58:49 +0000 Subject: [PATCH] Remove device tree booting dependency on CONFIG_SYS_BOOTMAPSZ The previous patch makes u-boot use the full accessible size of ram as the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined, which means boot_relocate_fdt() can be changed to depend solely on CONFIG_OF_LIBFDT.
