Alex,
while Einar is reworking the block size/geometry patches,
here is the current state of the external loader. While the real firmware
loader only supports fcp, this patch also allows to ipl dasd disks
(the differences in terms of on-disk format are pretty small).
This has the advantage of being able to zipl on LPAR and ipl in KVM and vice
versa for DASD disks.
This patch also contains code to IPL a new dasd bootmap (which is then
architectured) that will be created by a future zipl version. This zipl
version will then also allow to zipl a dasd/scsi disk under KVM and
create the same bootmap as under LPAR.
I was able to IPL CDL,LDL and FCP disks.
Can you have a look and give some review feedback?
PS: booting from dasd requires the correct geometry and blocksize
