[OpenPower-Firmware] HOMER structure

[Krystian Hebel]

Hello,

Our work on coreboot port for Talos II got to the point where we have to 
start
cores other than the one booted by SBE. As part of the procedure of bringing
them up we have to prepare HOMER structure (istep 15.1 in Hostboot, IPL
documentation [1] swaps 15.1 with 15.2). So far we have been trying to parse
Hostboot's code that builds it, but that seems to take eternity.

Is there any documentation that would explain the layout (preferably both
structural and functional), better than the one that can be found in IPL 
just
after 24.1? This would make our job much easier. Otherwise we are forced to
keep on going through the code, not only Hostboot's, but probably also HCODE
and/or OCC to understand what happens there.
