ppc4xx: Add custom linker script to board/*/config.mk

2009-11-02T15:29:04+00:00

These boards have special linker scripts right now. We can't use the
common 4xx linker script here. So overrride the linker script (LDSCRIPT)
in board/*/config.mk and choose the board specific version.

ppc4xx: Fix problems in some ppc4xx board Makefiles

2009-11-02T15:29:03+00:00

Some 4xx Makefiles didn't add $(SOBJ) to their board library. This was
no till now problem, since those boards included this object (init.o
most of the time) directly from their linker scripts. This patch clean
this up, so that all objects are now collected in the board library. This
is in preparation for the upcoming PPC4xx linker script consolidation.

ppc: Enable full relocation to RAM

2009-10-03T08:15:45+00:00

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.

Fix all linker script to handle all rodata sections

2009-03-20T21:39:12+00:00

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.

Align end of bss by 4 bytes

2008-11-18T22:13:16+00:00

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.
