2009-10-03ppc: Enable full relocation to RAMPeter Tyser
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.

2009-03-20Fix all linker script to handle all rodata sectionsTrent Piepho
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>
2008-11-18Align end of bss by 4 bytesSelvamuthukumar
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.

2008-08-26mpc7448hpc2: Fix PCI I/O space mapping.Randy Vinson
PCI I/O space is currently mapped 1:1 at 0xFA000000. Linux requires PCI I/O space to start at 0 on the PCI bus. This patch maps PCI I/O space such that 0xFA000000 in the processor's address space maps to 0 on the PCI I/O bus.

2008-08-19Clean up usage of icache_disable/dcache_disableKumar Gala
There is no point in disabling the icache on 7xx/74xx/86xx parts and not also flushing the icache. All callers of invalidate_l1_instruction_cache() call icache_disable() right after. Make it so icache_disable() calls invalidate_l1_instruction_cache() for us. Also, dcache_disable() already calls dcache_flush() so there is no point in the explicit calls of dcache_flush().

2008-06-12Change initdram() return type to phys_size_tBecky Bruce
This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>
2008-06-09Remove the deprecated CONFIG_OF_FLAT_TREEGerald Van Baren
Use CONFIG_OF_LIBFDT instead to support flattened device trees. It is cleaner, has better functionality, and is better supported. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2008-06-09Convert mpc7448hpc2 to CONFIG_OF_LIBFDTGerald Van Baren
This was configured to use the deprecated CONFIG_OF_FLAT_TREE, change to CONFIG_OF_LIBFDT. WARNING: This conversion is untested because I do not have a board to test it on. NOTE: The FDT blob (DTS) must have an /aliases/ethernet0 and (optionally) /aliases/ethernet1 property for the ethernet to work. Signed-off-by: Gerald Van Baren <vanbaren@cideas.com>
2008-05-21Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
