MIPS: incaip: remove custom u-boot.lds script

2013-01-30T23:27:39+00:00

Remove the board specific linker script. It is not
needed anymore, the unified MIPS linker script can
be used instead.

All incaip targets are producing identical binary
images after the change than before.

MIPS: remove OUTPUT_FORMAT from linker scripts

2013-01-30T22:34:10+00:00

The OUTPUT_FORMAT command in linker scripts
was always misused due to some endianess and
toolchain problems.

Use GCC flags to ensure proper output format,
and get rid of the OUTPUT_FORMAT commands in
the board specific u-boot.lds files.

common: Discard the __u_boot_cmd section

2012-10-22T15:29:42+00:00

The command declaration now uses the new LG-array method to generate
list of commands. Thus the __u_boot_cmd section is now superseded and
redundant and therefore can be removed. Also, remove externed symbols
associated with this section from include/command.h .

common: Add .u_boot_list into all linker files

2012-10-22T15:29:42+00:00

Add section for the linker-generated lists into all possible linker
files, so that everyone can easily use these lists. This is mostly
a mechanical adjustment.

MIPS: Introduce --gc-sections for MIPS

2011-05-09T15:08:10+00:00

All architectures but MIPS are using --gc-sections on final linking.
This patch introduces that feature for MIPS to reduce the memory and
flash footprint.

MIPS: update the MIPS u-boot.lds

2010-09-04T02:52:17+00:00

From the document, if set all arguments in "OUTPUT_FORMAT" to
"tradbigmips", then even add "-EL" to gcc we still get EB format.

pb1x00 is only used in Little-endian, so its default endian should be
set to LE.

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.

Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections

2008-01-12T19:31:39+00:00

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.
