[v2,2/3] hppa: Sync contents of hppa_hardware.h header file with SeaBIOS-hppa

Commit Message

Helge Deller May 28, 2022, 9:41 a.m. UTC

The hppa_hardware.h header file holds many constants for addresses and
offsets which are needed while building the firmware (SeaBIOS-hppa) and
while setting up the virtual machine in QEMU.

That's why this header file needs to be in sync between both source code
repositories. This patch adds a comment mentioning this dependency at
the top of this file and restores some DINO relevant offsets.
