From 789b6dceccbb852b0be235334b713467f88e2f8e Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 11 May 2016 07:44:59 -0700 Subject: x86: Prepare configuration tables in dedicated high memory region Currently when CONFIG_SEABIOS is on, U-Boot allocates configuration tables via normal malloc(). To simplify, use a dedicated memory region which is reserved on the stack before relocation for this purpose. Add functions for reserve and malloc.
