That is one way. The way I do it for our very simple LIF volume is as folows:
Once you have obtained the SOM ipl binary (after make), then:
% strip ipl
% mkipl ipl
% mklifhdr hdr x y z a b c (see the utility for what these #'s mean)
% cat hdr pad_file ipl vmlinux > bootstrap.bin
pad_file is a 1024 byte file full of 0.
I did forget to put this information into the README, sorry.
Eventually (next few days, hopefully), there will be one utility "mkimg"
that will automatically do everything above for you (particularly, picking
the numbers which have to do with entry points, etc).
Of course, vmlinux doesn't yet exist. I just have a simple dummy kernel
I use there, which hasn't been included in the distribution. If you
want to play around without the dummy kernel, just comment out the line
in ipl_c.c that branches to the kernel and remove "vmlinux" from the
concat line step above. You can then see the bootstrap run, but it won't
try to execute the kernel.
Have fun, Jason.
