* Align end of bss by 4 bytesSelvamuthukumar2008-11-18-1/+1
| | | | | | | | | | Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected. Signed-off-by: Selvamuthukumar <selva.muthukumar@e-coninfotech.com> Signed-off-by: Wolfgang Denk <wd@denx.de>

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | 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>
* Move "ar" flags to config.mk to allow for silent "make -s"Wolfgang Denk2006-10-09-1/+1

* 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.

* Prepare for SoC rework of ARM code:wdenk2005-04-02-4/+4
| | | | | - rename CONFIG_BOOTBINFUNC into CONFIG_INIT_CRITICAL - rename memsetup into lowlevel_init (function name and source files)
* Patch by George G. Davis, 24 Aug 2004:wdenk2004-10-10-1/+1
| | | | - update ARM boards to use constants from mach-types.h
* Patches by himba, 21 Aug 2004:wdenk2004-10-09-294/+286
| | | | | - fix some "use of label at end of compound statement" warnings - Define type of LCD panel on lubbock board if CONFIG_LCD is used
* Patch by Anders Larsen, 09 Jan 2004:wdenk2004-02-08-10/+5
| | | | | | | | | | ARM memory layout fixes: the abort-stack is now set up in the correct RAM area, and the BSS is zeroed out as it should be. Furthermore, the magic variables 'armboot_end' and 'armboot_end_data' of the linker scripts are replaced by '__bss_start' and '_end', resp., which is a further step to eliminate unnecessary differences between the implementation of the CPU architectures.
* * The PS/2 mux on the BMS2003 board needs 450 ms after power onwdenk2004-01-20-1/+1
| | | | | | | | | | | | before we can access it; add delay in case we are faster (with no CF card inserted) * Cleanup of some init functions * Make sure SCC Ethernet is always stopped by the time we boot Linux to avoid Linux crashes by early packets coming in. * Accelerate flash accesses on LWMON board by using buffered writes

| | | | | | | | Move most of the timer interrupt related PPC code to ppc_lib/interrupts.c * Patch by Anders Larsen, 17 Sep 2003: Bring ARM memory layout in sync with the documentation: stack and malloc-heap are now located _below_ the U-Boot code
* * Patches by Anders Larsen, 17 Sep 2003:wdenk2003-09-18-1/+1
| | | | | | | | | | - fix spelling errors - set GD_FLG_DEVINIT flag only after device function pointers are valid - Allow CFG_ALT_MEMTEST on systems where address zero isn't writeable - enable 3.rd UART (ST-UART) on PXA(XScale) CPUs - trigger watchdog while waiting in serial driver
* * Code cleanup:wdenk2003-06-27-100/+104
| | | | | | | | | - remove trailing white space, trailing empty lines, C++ comments, etc. - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c) * Patches by Kenneth Johansson, 25 Jun 2003: - major rework of command structure (work done mostly by Michal Cendrowski and Joakim Kristiansen)
* * Get (mostly) rid of CFG_MONITOR_LEN definition; compute real lengthwdenk2003-05-30-1/+1
| | | | | | | | instead CFG_MONITOR_LEN is now only used to determine _at_compile_ _time_ (!) if the environment is embedded within the U-Boot image, or in a separate flash sector. * Cleanup CFG_DER #defines in config files (wd maintained only)
* Patch by Kyle Harris, 20 May 2003:wdenk2003-05-23-1/+1
| | | | | In preparation for an ixp port, rename cpu/xscale and arch-xscale into cpu/pxa and arch-pxa.
