2009-06-12arm: unify linker scriptJean-Christophe PLAGNIOL-VILLARD
all arm boards except a few use the same cpu linker script so move it to cpu/$(CPU) that could be overwrite in following order SOC BOARD via the corresponding config.mk Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
2009-03-20Fix all linker script to handle all rodata sectionsTrent Piepho
A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. 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. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2009-02-07pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarityKumar Gala
The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and can be confusing when reading the code. Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used for system memory mapping purposes. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-11-18Align end of bss by 4 bytesSelvamuthukumar
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.

2008-08-12Update MTD to that of Linux 2.6.22.1William Juul
A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

2008-06-12Change initdram() return type to phys_size_tBecky Bruce
This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-05-20Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

2008-01-12Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk
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>
2007-10-31ppc4xx: Rework of 4xx serial driver (2)Stefan Roese
Change all linker scripts to reference the changed driver name 4xx_uart.o. Note: In most cased all these explicit referencing of these object files in the linker scripts is not neccessary. Only for manually embedded environment into the U-Boot image, which is not done is most cases. Signed-off-by: Stefan Roese <sr@denx.de>

2006-09-01Add support for a saving build objects in a separate directory.Marian Balakowicz
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.
