* ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-0/+1
| | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Move ppc4xx headers to powerpc include directoryStefan Roese2010-09-23-1/+1
| | | | | | | | | This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: TLB init file cleanupStefan Roese2010-04-19-13/+13
| | | | | | | | | | | | 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>
* Replace "#include <asm-$ARCH/$FILE>" with "#include <asm/$FILE>"Peter Tyser2010-04-13-2/+2
| | | | | | | | | | The appropriate include/asm-$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>
* ppc4xx: Remove board specific linker scripts from most PPC4xx boardsStefan Roese2009-11-02-145/+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 Tyser2009-10-03-1/+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 Roese2009-09-28-30/+30
| | | | | | | 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 Roese2009-09-11-9/+9
| | | | | | | | | | | | | | | | 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 Piepho2009-03-20-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Align end of bss by 4 bytesSelvamuthukumar2008-11-18-0/+1
| | | | | | | | | | 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. Signed-off-by: Selvamuthukumar <selva.muthukumar@e-coninfotech.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
