[PATCH v3 00/10] sparc: unify piggyback - and fix tftpboot.img on

[Sam Ravnborg]

The following set of 10 patches unify piggyback for
sparc32 and sparc64.
This has the side effect that we fix a longstanding bug in
sparc64 so we can now generate tftpboot.img on a x86 box.

The patch is test on a sparc32 system where I got a
ext2 image mounted and working.

On sparc64 I managed to boot a kernel on my Sun Blade 100
but the kernel stopped with a message:

	"console [tty0] enabled, bootconsole disabled"

So I did not reach the point where it try to mount 
the appended image.
Any hints what is wrong is appreciated!
[I guess I have the wrong framebuffer driver - but I do not know which is the right one]

This was anyway enough that I have concluded that it works
better than before.
I have only tested this using my x86 build host.

Changes since v1:
- Updated copyrights (from from Josip Rodin)
- Fixed algorithm to locate "HdrS" (from Josip Rodin)
- Verified the endian fixes (based on code received from Julian Calaby)

Please apply.

	Sam

I forgot the "-M" flag to "git format-patch". So the diff
is not review-able.

This is a pure rename with no additional edits.

I can resend path (or full serie) if you prefer.

You might need the PGX64 framebuffer driver for the 'Blade 100.

Just tried it - stuck at the same place :-(

Thanks for the input anyway.

EARLYFB is enabled and works - so I have something working..
It may also be a different issue - the kernel may hang
after the call to register_console().

I will try to debug tomorrow.

The onboard graphics chip is ATI mach64, not PGX64.

It's not necessary.

I've applied these patches, thanks a lot Sam.

Isn't the PGX64 the same graphics chipset? Can confirm the issue.

Thanks,
