Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

tsutsui | Make zaurus kernels use symbol tables loaded by the bootloader.
Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).
Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.
No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html
Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).
Worth to pullup to both netbsd-8 and netbsd-9.

Make zaurus kernels use symbol tables loaded by the bootloader.
Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).
Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.
No particular comment on port-zaurus@:

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).
Worth to pullup to both netbsd-8 and netbsd-9.

Explicitly set empty LINKENTRY to keep ENTRY address specified in ldscript.
This fixes kernel boot failures of NetBSD/zaurus 8.x and later.
While here, also set empty TEXTADDR also specified in ldscript.
See my post in port-zaurus@ for details:

Fix another boot failure issue of NetBSD/zaurus 8.x and later.
It looks some cacheline alignment restriction so that zbsdmod.o in
NetBSD/zaurus 8.x release cannot jump to a loaded kernel properly.
Adding an explicit alingment pseudo op to put all instructions
between I-cache flush and jumping to the loaded kernel into the
same cacheline solves the issue.
See my post in port-zaurus@ for details:
https://mail-index.netbsd.org/port-zaurus/2019/10/22/msg000069.html
Should be pulled up to netbsd-8 and netbsd-9.
-
Misc cleanup to avoid future confusion.
- Remove more unnecessary debug sections
- Use DBG instead of COPTS to specify -Os as defined in bsd.prog.mk
- Use CFLAGS and CPPFLAGS correctly
- Explicitly set -ffreestanding
-
Make sure to clear bss before jumping to a kernel copied from load buffer.
This will fix yet another boot failure issue
"screen white-out after loading a kernel"

Yes, we need to load symbols, but we don't need the whole DDB infrastructure
for that.
bye ddb and we fit again.
