From d8d21e699d7fcfb6ab11635110266dd09b7edc62 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 16 Feb 2009 18:03:14 -0500 Subject: boards: move board_get_enetaddr() into board-specific init The environment is the canonical storage location of the mac address, so we're killing off the global data location and moving everything to querying the env directly. Rather than have the common ppc code have board-specific hooks, move the board_get_enetaddr() function into the board-specific init functions.

Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is.
