* ppc4xx: Flush complete dcache in relocate_code()Stefan Roese2010-11-28-6/+7
| | | | | | | | | When the cache is enabled in SDRAM we need to flush not only the global data area but also the bd_info struct in relocate_code. This patch now flushed the complete dcache (all dcache lines) via flush_dcache() instead of adding a flush_dcache_range() call for bd_info since this is faster.

* POWERPC: enable --gc-sections and -ffunction-sections -fdata-sectionsWolfgang Denk2010-11-27-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The switch from archive libraries to partial linking has introduced a number of problems, that are non-trivial to solve. For example, it is no longer possible to include individual object files in the linker script as we did before for example in the case of boards with embedded environment to fill up the gap caused by the need to align the environment on flash erase block boundaries. The best (but unfortunately not easiest) approach to address this problem is to enable -ffunction-sections (and -fdata-sections) so we can again (and even in much finer granularity) place certain code where we want it. When doing this step, it seems only consequent to also add --gc-sections which has the added benefit of reducing the memory footprint of the U-Boot image (both in flash and in RAM). Unfortunately, this requires changes to a lot of linker scripts.

* arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings workWolfgang Denk2010-11-26-49/+8
| | | | | | | | | | | | | | | | | | | | | | | | | As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

* | Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-28/+28
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-1/+14
| | | | | | | | | | | | | | | | | | 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.

Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.

After the testing, DDR is remapped with up to 2GB memory from the lowest address as normal. If memory test fails, DDR DIMM SPD and DDR controller registers are dumped for further debugging.

DECO was trying to share from itself or from another DECO but the two Non-SEQ LIODN values didn't match or the "shared from" DECO's Descriptor required that the SEQ LIODNs be the same and they aren't. Since high traffic rates cause DECOs to begin to start sharing shared descriptors amongst themselves, and DECOs inherit job queue LIODNs when accessing shared descriptors, and a recently discovered rev.2 h/w erratum requires all sharing job queues in a partition have same liodn assignment, reassign the first job queue's liodn assignment to the rest.
