| * ppc4xx: TLB init file cleanupStefan Roese2010-04-19-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>
* | Move arch/ppc to arch/powerpcStefan Roese2010-04-21-2/+2
|/ | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

* Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser2010-04-13-1/+1
| | | | | | | | | | The appropriate include/asm-$ARCH directory should already by symlinked to include/asm so using the whole "asm-$ARCH" path is unnecessary. This change should also allow us to move the include/asm-$ARCH directories into their appropriate lib/$ARCH/ directories. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* POST: Remove duplicated post_hotkey_pressed() functionsStefan Roese2009-12-07-11/+0
| | | | | | | | | | | | | This patch introduces a weak default function for post_hotkey_pressed(), returning 0, for boards without hotkey support. The long-running tests won't be started on those boards. This default function was implemented in many board directories. By implementing this weak default we can remove all those duplicate versions. Boards with hotkey support, can override this weak default function by defining one in their board specific code. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Consolidate pci_master_init() functionStefan Roese2009-11-19-17/+0
| | | | | | | | This patch removes the duplicted implementations of the pci_master_init() function by introducing a weak default function for it. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Consolidate pci_pre_init() functionStefan Roese2009-11-19-59/+1
| | | | | | | | | This patch removes the duplicted implementations of the pci_pre_init() function by introducing a weak default function for it. This weak default has a different implementation for some PPC variants. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Consolidate pci_target_init() functionStefan Roese2009-11-19-54/+3
| | | | | | | | | | This patch removes the duplicted implementations of the pci_target_init() function by introducing a weak default function for it. This weak default has a different implementation for 440EP(x)/GR(x) PPC's. It can be overridden by a board specific version (e.g. PMC440, korat).

* ppc4xx: Remove duplicated is_pci_host() functionsStefan Roese2009-11-09-21/+0
| | | | | | | | | This patch introduces a weak default function for is_pci_host(), returning 1. This is the default behaviour, since most boards only implement PCI host functionality. This weak default can be overridden by a board specific version if needed. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Remove board specific linker scripts from most PPC4xx boardsStefan Roese2009-11-02-142/+0
| | | | | | | | | 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>

| * ppc: Enable full relocation to RAMPeter Tyser2009-10-03-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ppc4xx: Convert PPC4xx UIC defines from lower case to upper caseStefan Roese2009-09-28-23/+23
| | | | | | | The latest PPC4xx register cleanup patch missed the UIC defines. This patch now changes lower case UIC defines to upper case. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Big cleanup of PPC4xx definesStefan Roese2009-09-11-32/+32
| | | | | | | | | | | | | | | | 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>
* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* 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>
