David S. Miller 0032c85745 sparc: Fix piggyback with newer binutils.
Newer versions of binutils mark '_end' as 'B' instead of 'A' for
whatever reason.

To be honest, the piggyback code doesn't actually care what kind
of symbol _start and _end are, it just wants to find them and
record the address.

So remove the type from the match strings.

All ARCHs have the same definition of MKIMAGE. Move it to Makefile.lib
to avoid duplication.

All ARCHs have similar definitions of cmd_uimage. Place a sufficiently

Sam Ravnborg 56818a6f91 sparc: rename piggyback_32 to piggyback
Now that we use the same piggyback for 32 and 64 bit
we can drop the _32 suffix.
Include some trivial unification in the Makefile
now that 32 and 64 bit can share the same piggyback command.

Sam Ravnborg 1075c4ef70 sparc: fix tftpboot.img for sparc64 on little-endian host
piggyback_32 adapted to support sparc64:
- locating "HdrS" differs for sparc and sparc64
- sparc64 updates a_text, a_data + a_bss in the final a.out header

Updated Makefile to use piggyback_32 for sparc64.
Deleted the now unused piggyback_64.c

piggyback_32.c is host endian neutral and works on both
little-endian and big-endian hosts.
This fixes a long standing bug where sparc64 could not
generate tftpboot.img on a x86 host.

Removing ELF support because:

Julian Calaby 8944146daa sparc32: Fix makefile not generating required files
The tftpboot build was failing with missing file errors.

It turns out that $(obj)/image wasn't being generated which was causing the a.out conversion to be skipped and hence piggyback to be called with nonexistent files.

Sam Ravnborg 52da82cfb5 sparc: fix tftpboot.img build
Kjetil Oftedal mentioned that piggyback_32 was failing
when building a sparc image.

I tracked this down to the fact that the kernel no longer
provided an absolute symbol named "end".

Commit 86ed40bd6f ("sparc: unify sections.h")
renamed end to _end but failed to update piggyback_32.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
