avr32: add ATAG_BOARDINFO

2011-05-18T05:56:54Z

This patch adds a new ATAG_BORADINFO to U-Boot. This tag is intended to hand over the bd->bi_board_number to the linux kernel for early stage board information like a board revision or other kind of board specific decisions necessary before the linux peripherial drivers are up.

avr32: use single linker script

2011-05-18T05:56:53Z

This patch move the atstk100x linker script to $(CPUDIR) and delete other pure copies of this file in each board directory. Signed-off-by: Andreas Bießmann

avr32/config.mk: simplify PLATFORM_RELFLAGS

2011-05-18T05:56:53Z

This patch removes PLATFORM_RELFLAGS from board specific config.mk files and define them in arch specific config.mk file. Signed-off-by: Andreas Bießmann

avr32: fix linking

2011-05-18T05:56:52Z

Make STANDALONE_LOAD_ADDR configurable per board

2011-04-12T20:58:32Z

Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR and allow that the architecture-specific default value gets overwritten by defining the value in the board header file.

rename _end to __bss_end__

2011-03-27T17:18:37Z

Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier

Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOC

2010-10-29T19:32:07Z

By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.
