 1.7  28-Apr-2008  martin Remove clause 3 and 4 from TNF licenses
 1.6  30-Oct-2007  tsutsui branches: 1.6.16; 1.6.18; 1.6.20;
Add support for netboot via tlp0 with standalone tlp(4) driver
taken from arch/sandpoint/stand/netboot.
There are still some kludge but it just works on RaQ and RaQ2.
 1.5  17-Oct-2007  garbled 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.
 1.4  25-Jul-2007  tsutsui branches: 1.4.4; 1.4.6; 1.4.10;
Flush all cache data at the beginning of the bootloader.

Fixes silent hangs after loading 4.0_BETA2 GENERIC kernel
on Qube2 (and RaQ2) with 256MB RAM, reported and tested
by James Hartley on port-cobalt.

Obviously this should be pulled up to netbsd-4.
 1.3  11-Dec-2005  christos branches: 1.3.24; 1.3.30; 1.3.38; 1.3.40; 1.3.42; 1.3.44;
merge ktrace-lwp.
 1.2  07-Jan-2004  cdi branches: 1.2.16;
Pass some info from the boot loader to the kernel:

- Kernel image name
- Symbol table
- A flag indicating console presence (could be clobbered if not passed)

Add _rtt() entry to the boot loader code.
 1.1  25-Jun-2003  cdi branches: 1.1.2;
Initial commit of a 1-stage boot loader for NetBSD/cobalt. Only booting off
the hard drive is supported at the moment.

sys/arch/cobalt/stand/boot/version: revision 1.6
sys/lib/libsa/dev_net.h: revision 1.5
Add an extern decl of try_bootp variable here since MD sources could set it.

In device_register(), check booted devices more properly:
- check "tlp" name on netboot
- use ata channel and drive numbers to check wd unit

Assume netboot if "nfsroot=/path" is specified in bootstring.

Use PCI bus/dev/function numbers rather than device unit
to check first tlp in device_register().

Add support for netboot via tlp0 with standalone tlp(4) driver
taken from arch/sandpoint/stand/netboot.
There are still some kludge but it just works on RaQ and RaQ2.

Fix my stupid bug in cache flush code and remove one kludge for it.

- use chaned mode for RX descs and allocate only one desc per each cacheline
to avoid possible race condition between CPU writeback vs DMA write
- remove unnecessary FS and LS bits from RxD->xd0
(sys/dev/ic/tulipvar.h sets them but maybe they are ignored?)
