* ppc4xx: Use correct io accessors for esd 405 boardsMatthias Fuchs2009-03-20-1/+1
| | | | | | | | | This patch replaces in/out8/16/32 macros by in/out_8/_be16/_be32 macros. Also volatile pointer references are replaced by the new accessors. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Signed-off-by: Stefan Roese <sr@denx.de>

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Align end of bss by 4 bytesSelvamuthukumar2008-11-18-0/+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>

* ppc4xx: Remove obsolete or unused functions from some esd boardsMatthias Fuchs2008-09-03-10/+0
| | | | | | | | | This patch removes initdram() and testdram() from most esd 405 platforms. Some boards also have an empty dummy implementation of misc_init_f(). This is also removed. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com> Signed-off-by: Stefan Roese <sr@denx.de>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | 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>
* Big white-space cleanup.Wolfgang Denk2008-05-21-4/+4
| | | | | | | | | | | 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>

* 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>
* ppc4xx: Rework of 4xx serial driver (2)Stefan Roese2007-10-31-1/+1
| | | | | | | | | | 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>

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-6/+13
| | | | | | | | | | | | | | | | | | | | | 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.
