* integrator: convert to new build systemLinus Walleij2011-09-03-5/+0
| | | | | | | | | | | | | | | | | This deletes the integrator split_by_variant.sh script and defines a number of unique board types for the core modules that are meaningful to support for the Integrator AP/CP, i.e. the ones that did not just say "unsupported core module" in split_by_variant.sh. If more core modules need to be supported they are easy to add. We delete all the old cruft in Makefile and MAKEALL that was working around the old way of building boards. We create a unique config file per board to satisfy the build system, but they are just oneliners that include the existing integratorap.h and integratorcp.h configs.

* Convert ISO-8859 files to UTF-8Albert ARIBAUD2011-08-04-2/+2
| | | | | | | | There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

* arm: fix incorrect monitor protection region in FLASHPo-Yu Chuang2011-03-27-0/+6
| | | | | | | | | | | Monitor protection region in FLASH did not cover .rel.dyn and .dynsym sections, because it uses __bss_start to compute monitor_flash_len. Use _end instead. Add _end to linker scripts for end of u-boot image Add _end_ofs to all the start.S. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>
* rename _end to __bss_end__Po-Yu Chuang2011-03-27-2/+2
| | | | | | | Currently, _end is used for end of BSS section. We want _end to mean end of u-boot image, so we rename _end to __bss_end__ first. Signed-off-by: Po-Yu Chuang <ratbert@faraday-tech.com>

* arm: fixloop(): do not use r8 for relocationAndreas Bießmann2010-12-09-3/+3
| | | | | | | | | r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* arm: relocate_code(): do not set register uselessAndreas Bießmann2010-12-09-2/+2
| | | | | | | | | In case we are still at relocation target address before relocation we do not need to load the registers needed for relocation. We should instead skip the whole relocation part and jump over to clear_bss immediately. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>
* arm: copy_loop(): use scratch registerAndreas Bießmann2010-12-09-5/+5
| | | | | | | | | This patch uses r1 as scratch register for copy_loop(). Therefore we do not longer need r7 for the storage of relocate_code()'s 'addr_moni' (the destination address of relocation). Therefore r7 can be used later on for other purposes. Signed-off-by: Andreas Bießmann <andreas.devel@googlemail.com>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* Drop support for CONFIG_SKIP_RELOCATE_UBOOTWolfgang Denk2010-10-29-2/+0
| | | | | | | | | | | | | | | | For ARM systems, before ELF relocation was introduced, CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the U-Boot image from whereever it was loaded to it's link address (CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation was performed at all, it was just a memcpy(). With ELF relocation, this does not work like that any more, and related boards need to be fixed anyway. So don't keep this relict any longer. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-105/+0
| | | | | | | | | | | | | | | | When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>
* ARM: use the same branch insn on all architecturesWolfgang Denk2010-10-26-1/+1
| | | | | | | | | | | | | | | For the "fixloop" implementation in start.S a number of different instructions was used. Unify code so all architectures use "blo" here because it is more robust in case of incorrect alignments.

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-4/+4
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-4/+4
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* arm: bugfix: replace ble with blo in start.S filesAlbert Aribaud2010-10-11-5/+5
| | | | | | | | | | | Generalized misuse of ble within relocation and bss initialization loops caused one iteration too many. Instead of ble ('branch if lower or equal'), use blo ('branch if lower'). While we're at it, fix all 'addreee' typos. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>

* ARM: Align stack to 8 bytesVitaly Kuzmichev2010-06-22-0/+1
| | | | | | | | | | | | | The ARM ABI requires that the stack be aligned to 8 bytes as it is noted in Procedure Call Standard for the ARM Architecture: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html Unaligned SP also causes the problem with variable-length arrays allocation when VLA address becomes less than stack pointer during aligning of this address, so the next 'push' in the stack overwrites first 4 bytes of VLA.
