The exception vector table will become part of the uncompressed image,
so we can't reference them from the lowlevel init stuff anymore.

Calculating the offset between runtime and linked address makes the
intention of the binary copy function a bit more clear.

The ep93xx needs a special value at offset 0x1000. Rather than
do special handling in the linker file add aa header section
as done on i.MX.

With compressed image support TEXT_BASE will become the base
address of the uncompressed image. What the boards want instead
is the base address of the decompressor code or, if not compressed,
the base address of the uncompressed image. Use _text which is
the correct one for both cases.

Is it possible to add the section to the ENTRY macro?

I'm not sure. I was pretty sure that some assembly functions fall
through to the next function. I cannot find any examples though.

For example we have this:
.section .text.__divsi3
ENTRY(__divsi3)
ENTRY(__aeabi_idiv)
...

and also:
ENTRY(__lshrdi3)
ENTRY(__aeabi_llsr)
However, this is the rare exception. How about
adding __ENTRY for these cases?

I think it's better to keep the ENTRY semantics (which is derived from
the Linux Kernel) and just live with it that we have to add the .section
at the beginning of each function.

The changes in this file are completely wrong. These functions use
different jump labels (1b, 1f,...) to jump over function borders.
The bad thing is that the compiler does not issue any warning, it only
generates broken code.
Will fix.

This allows for creating a lzo compressed binary. This is done by
linking barebox twice using two linker scripts. One is the regular
uncompressed binary but without the lowlevel init stuff. The
other contains the lowlevel init stuff, the decompressor and the
compressed binary.

Where is barebox-compressed set?
I tried it and it fails to link:
LD arch/arm/lib/built-in.o
LD barebox-uncompressed
SYSMAP System.map
OBJCOPY barebox-uncompressed.bin
LZO barebox-uncompressed.bin.lzo

It shouldn't link all the -built-in.o into the uncompressor, should it?
Or is it supposed to work via --gc-sections trick?
Thanks,
Johannes

Yes, it works using --gc-sections. Are you building a defconfig or a
custom one? If the error above is correct start_barebox is referenced
from the decompressor code. This should not happen.

I'm building a custom one (unpublished code). It has some SPI flash
boot assembly code, I guess that might cause the issue wrt the new section
annotations. I'll look at it tomorrow. However, I still wonder
about the empty $(barebox-compressed)?
Thanks

It's empty here aswell, so this shouldn't be a problem. Though I should
probably simpy remove it.

OK, got it to work now. I had a "b start" in my SPI flash boot code
to skip low level init when it was loaded into RAM via JTAG.
That needed to be changed to "b compressed_start". It seems
there is no real support in ld to debug this, I added --cref
to LDFLAGS_barebox but I still couldn't see why stuff from
common/built-in.o gets pulled into the uncompressor.
BTW, I briefly tried the lzo update from
http://lkml.org/lkml/2012/7/16/355
(don't have much time to do real benchmarks, just tried
"time uncompress somefile.lzo somefile"),
but it seems to be slower on ARM926 than the old version
(504ms vs 362ms).
Thanks,
Johannes

need to check here if we are at TEXT_BASE (I mean if the code run where we are
supposed to uncompress
otherwise on at91 it will not work as the bootstrap put use at TEXT_BASE
so we have need to link at an other address
but the decompressor need work anyway by copying itself with the data before
of after the TEXT_BASE
and we should take the uncompress size about 4 times the compressed one.
There is nearly no change to compress more than 75%
otherwise Tested by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
