* Use jr as register jump instructionShinya Kuribayashi2008-04-18-1/+1
| | | | | | | | | | Current assembler codes are inconsistent in the way of register jump instruction usage; some use jr, some use j. Of course GNU as allows both usages, but as can be expected from `Jump Register' the mnemonic `jr' is more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage at all.

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-2/+2
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>
* [MIPS] board/gth2/lowlevel_init.S: Fix a build warningShinya Kuribayashi2007-11-19-0/+4
| | | | | | | | | | | | lowlevel_init.S: Assembler messages: lowlevel_init.S:413: Warning: Pretending global symbol used as branch target is local. Looking at codes, the `memtest' and `clearmem' are intentional mixed use of `global symbols' and `label' for debugging purpose. To make it build, just disable global-symbols-use for now. As a result `memtest' still remains as unused, but leave it be... Signed-off-by: Shinya Kuribayashi <shinya.kuribayashi@necel.com>

* Fixed mips_io_port_base build errors.Jean-Christophe PLAGNIOL-VILLARD2007-11-17-2/+4
| | | | | | | | | | | | | | | | | | | | This patch has been sent on: - 29 Sep 2007 Although mips_io_port_base is currently a part of IDE command, it is quite fundamental for MIPS I/O port access such as in[bwl] and out[bwl]. So move it to MIPS general part, and introduce `set_io_port_base()' from Linux. This patch is triggered by multiple definition of `mips_io_port_base' build error on gth2 (and tb0229 also needs this fix.) board/gth2/libgth2.a(gth2.o): In function `log_serial_char': /home/skuribay/devel/u-boot.git/board/gth2/gth2.c:47: multiple definition of `mips_io_port_base' common/libcommon.a(cmd_ide.o):/home/skuribay/devel/u-boot.git/common/cmd_ide.c:712: first defined here make: *** [u-boot] Error 1 Signed-off-by: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-7/+11
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
