From aabd7ddb889aec3c6c4139974f66a44e2ce46ba5 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 7 Dec 2015 11:05:29 -0800 Subject: common: Rewrite hiding the end of memory As the name may be confusing, the CONFIG_SYS_MEM_TOP_HIDE reserves some memory from the end of ram, tracked by gd->ram_size. It is not always the top of u-boot visible memory. Rewrite the macro with a weak function to provide flexibility for complex calcuation. Legacy use of this macro is still supported.
