From 409dbce54b57b85bd229174da86d77ca08508508 Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Sun, 14 Mar 2010 21:20:59 +0100 Subject: load_elf: replace the address addend by a translation function A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address. The patch also convert all machines that have an addend, simplify the PowerPC kernel loading and fix the MIPS kernel loading using this new feature. Other machines may benefit from this feature.
