From 63f559cd12e64825df78c1774b707ac1782110c0 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Mon, 5 Dec 2011 12:09:22 +0000 Subject: x86: Import code from coreboot's libpayload to parse the coreboot table This change also forces the lib_sysinfo structure to be in the .data section. Otherwise it ends up in the .bss section. U-boot assumes that it doesn't need to copy it over during relocation, and instead fills that whole section with zeroes. If we really were booting from ROM that would be appropriate, but we need some information from the coreboot tables (memory size) before then and have to fill that structure before relocation. We skirt u-boot's assumption by putting this in .data where it assumes there is still read only but non-zero data.
