RE: [iPAQ] Compaq bootldr partition definition

If you want to learn more about the iPAQ, then should work off of the
handhelds.org CVS tree. Why, you ask, why work off of handhelds.org
rather than the ARM (rmk) kernel patches? Because of the time lag in
the system:

Linux <--> ARM <--> iPAQ

Linux pushes out new kernels. Russell maintains patches against the
Linus kernels (and occassional the -ac kernel patches) that support
dozens of ARM-based devices. The handhelds kernel developers work off
of a kernel/RMK patch and pull in a bunch of other fixes to develop
iPAQ-specific kernel stuff. We also pull in bits and pieces from other
patch systems; for example, PCMCIA, JFFS2, and MTD. Periodically we feed
our patches and fixes back up to either Linus, Alan, or Russell. They
may or may not include our patches into their next release.
Periodically a kernel update comes from Russell that breaks
iPAQ-specific stuff - so we spend a few days, track it down, and fix it
for the iPAQ.

The net result is there can be a considerable time- and feature-lag
between the -rmk kernels and the -hh kernels. You just found one of
those. If you do wish to learn more about the iPAQ, you will find that
the -hh kernels contain far more useful iPAQ information than the raw
-rmk releases...and they are much more likely to work correctly with our
bootloader.
