2011-11-03Reduce build timesWolfgang Denk1-1/+2
U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.

2010-12-09arm: fixloop(): do not use r8 for relocationAndreas Bießmann1-3/+3
r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
2010-12-09arm: relocate_code(): do not set register uselessAndreas Bießmann1-2/+2
In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation. We should instead skip the whole relocation part and jump over to clear_bss immediately. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
2010-12-09arm: copy_loop(): use scratch registerAndreas Bießmann1-5/+5
This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss values in arm920t/at91/timer driver. The usage of bss values in driver before initialisation of bss is forbidden.

2010-11-17Switch from archive libraries to partial linkingSebastien Carlier8-16/+16
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 <sebastien.carlier@gmail.com>

2010-10-29Drop support for CONFIG_SKIP_RELOCATE_UBOOTWolfgang Denk1-2/+0
For ARM systems, before ELF relocation was introduced, CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the U-Boot image from whereever it was loaded to it's link address (CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation was performed at all, it was just a memcpy(). With ELF relocation, this does not work like that any more, and related boards need to be fixed anyway. So don't keep this relict any longer. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
2010-10-29Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk1-144/+0
When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

2010-10-26Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk1-3/+4
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

2010-10-18Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk3-5/+5
The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.
