* powerpc/fsl-pci: Determine pci_controller based on cfg addr for dts fixupKumar Gala2011-01-14-40/+3
| | | | | | | | | | | | | | Previously we passed in a specifically named struct pci_controller to determine if we had setup the particular PCI bus. Now we can search for the struct so we dont have to depend on the name or the struct being statically allocated. Introduced new find_hose_by_cfg_addr() to get back a pci_controller struct back by searching for it means we can do things like dynamically allocate them or not have to expose the static structures to all users.

* MPC8xxx DDR: align informational printsBecky Bruce2011-01-14-2/+3
| | | | | | | | | | | | | | | | | | | | Add spaces to cause the informational prints to line up with the ones from init_func_ram() in board.c. Output now looks like this: .... DRAM: Detected 4096 MB of memory This U-Boot only supports < 4G of DDR You could rebuild it with CONFIG_PHYS_64BIT DDR: 2 GiB (DDR2, 64-bit, CL=5, ECC off) .... The prints from lbc_sdram_init() have also been modified to line line up and changed to start with "LBC SDRAM" instead of the confusing "SDRAM".

* mpc85xx boards: initdram() cleanup/bugfixBecky Bruce2011-01-14-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences: 1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner. 2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad. The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* mpc85xx/tlb.c: Allow platforms to specify wimge bitsBecky Bruce2011-01-14-1/+5
| | | | | | | | | | | | | Some platforms might want to override the default wimge=0 for DDR. Add CONFIG_SYS_PPC_DDR_WIMGE for those platforms to use. This will initially only be used by TQM85xx, but could be useful for other boards or testing going forward. Note that the name of this define is not 85xx-specific. WIMGE is a fairly universal concept, so any ppc platforms that require different WIMGE settings for DDR can use the same #define.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some systems need to relocate the env_addr pointer early because the location it points to will get invalidated before env_relocate is called. One example is on systems that might use a L2 or L3 cache in SRAM mode and initialize that cache from SRAM mode back to being a cache in cpu_init_r. We set this on the 85xx boards that have support for NAND, SPI, or SDHC/MMC boot support as they use a secondary cache in SRAM mode and need the env_addr pointer relocated since we change from SRAM to normal cache mode in cpu_init_r. Also removed CONFIG_SYS_SPL as its not used anywhere. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* POWERPC: enable --gc-sections and -ffunction-sections -fdata-sectionsWolfgang Denk2010-11-27-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
