2009-11-02ppc4xx: Remove board specific linker scripts from most PPC4xx boardsStefan Roese
All these linker scripts can be removed since the new common ppc4xx linker script should be able to handle all of those boards. Please test and report problems. Thanks. Signed-off-by: Stefan Roese <sr@denx.de>
2009-10-03ppc: Enable full relocation to RAMPeter Tyser
The following changes allow U-Boot to fully relocate from flash to RAM: - Remove linker scripts' .fixup sections from the .text section - Add -mrelocatable to PLATFORM_RELFLAGS for all boards - Define CONFIG_RELOC_FIXUP_WORKS for all boards Previously, U-Boot would partially relocate, but statically initialized pointers needed to be manually relocated.

2009-09-28ppc4xx: Convert PPC4xx SDRAM defines from lower case to upper caseStefan Roese
The latest PPC4xx register cleanup patch missed some SDRAM defines. This patch now changes lower case UIC defines to upper case. Also some names are changed to match the naming in the IBM/AMCC users manuals (e.g. mem_mcopt1 -> SDRAM0_CFG). Signed-off-by: Stefan Roese <sr@denx.de>

2009-09-11ppc4xx: Big cleanup of PPC4xx definesStefan Roese
This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>
2009-08-09Dual-license IBM code contributionsJosh Boyer
It was brought to our attention that U-Boot contains code derived from the IBM OpenBIOS source code originally provided with some of the older PowerPC 4xx development boards. As a result, the original license of this code has been carried in the various files for a number of years in the U-Boot project. IBM is dual-licensing the IBM code contributions already present in U-Boot under either the terms of the GNU General Public License version 2, or the original code license already present.

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>
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.

2008-06-12Change 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>
2008-06-03ppc4xx: Remove superfluous dram_init() call or replace it by initdram()Stefan Roese
Historically the 405 U-Boot port had a dram_init() call in early init stage. This function was still called from start.S and most of the time coded in assembler. This is not needed anymore (since a long time) and boards should implement the common initdram() function in C instead. This patch now removed the dram_init() call from start.S and removes the empty implementations that are scattered through most of the 405 board ports. Some older board ports really implement this dram_init() though. These are: csb272 csb472 ERIC EXBITGEN W7OLMC W7OLMG I changed those boards to call this assembler dram_init() function now from their board specific initdram() instead. This *should* work, but please test again on those platforms. And it is perhaps a good idea that those boards use some common 405 SDRAM initialization code from cpu/ppc4xx at some time. So further patches welcome here. Signed-off-by: Stefan Roese <sr@denx.de>
2008-05-21Big 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.
