OK, I'm getting a little closer (I think)...
I have managed to coerce U-Boot into processing a bzImage and loading
what appears to be the correct data @ 0x10000. According to this
(http://en.wikipedia.org/wiki/File:Linux-kernel-vmlinux.png) I think
that is all about right.
Doing a memory dump from 0x10000 gives:
00010000: 57e58955 ec835356 085d8b18 560c758b U..WVS....]..u.V
00010010: 000220e8 6a585f00 025e6806 cee80004 . ..._Xj.h^.....
00010020: e8000000 00000083 6850595a 0004027f ........ZYPh....
00010030: 0000bc68 2404c700 0004029d 0000b0e8 h......$........
The disassembly of which is:
mov ebp, esp
sub esp, 18h
mov ebx, [ebp+8]
mov esi, [ebp+0Ch]
call near ptr 235h
call near ptr 0F1h
call near ptr 0ABh
mov dword ptr [esp], 4029Dh
So it looks like legit code (setting up a stack frame etc)
But where to go from here?
