[PATCH v2 0/4] Build openbios on powerpc64 host
by Laurent Vivier
This series of patches allows to build openbios on a
powerpc64 host. It has been tested with the following targets:
ppc, sparc32, sparc64. It has also been tested on x86_64 host
with the same targets.
v2: remove patches 3/5 and 4/5 of the first series and replace it
with patch 4/4. We don't include the system includes using
full pathname but use '-iquote' intead of '-I'
A preliminary patch is needed for fcode-utils, as "toke" is
broken on big endian architecture:

[commit] r1353 - in trunk/openbios-devel: arch/ppc/qemu drivers include/drivers
by repository service
Author: mcayland

New Revision: 1353

Log:
ppc: add ob_ide_quiesce() and call it from the PPC CIF quiesce word
Add a new ob_ide_quiesce() function and hook it into QEMU PPC's ciface_quiesce()
routine to properly prepare the drives for transferring control to the operating
system.
Without this OS 9 becomes confused about the initial drive state on boot and
refuses to correctly detect and initialise it.
Based upon an original patch by Cormac O'Brien <cormac(a)c-obrien.org>.

[PATCH 0/5] GSoC OS 9 boot patchset update
by Mark Cave-Ayland
Hi all,
Here is a slightly reworked version of Cormac's GSoC MacOS 9 patchset which
I believe is ready to apply.
A considerable amount of time was spent by Cormac finding the correct set of
properties required by OS 9 whilst also not regressing existing images. The
patchset in it's current form here passes all of my local PPC image tests
while still progressing OS 9 boot as before.
The patches are mostly untouched other than adding my SoB except for patch 3
where I altered the version referenced in the comment and commit message,
and splitting patch 4 into 2 separate patches as requested by Alex, along with
some other minor tidy-ups.
Note: patch 1 from Cormac's original patchset was a hack from me to allow the
OS 9 bootloader to run, however it is not included here because it causes
problems with yaboot. People interested in the OS 9 work can apply the patch
by hand in the meantime.
Several review comments suggested the use of a helper function for string
properties, however recent work on SPARC has shown that building up string
properties in this way is prevalent throughout the OpenBIOS codebase. In the
interest of progressing work in this area, I'd like to apply the patches as-is
and then globally rework string properties using a helper at a later date.

SPARC64: fix PCI-EBus bridge ranges property
The child address of the PCI-EBus bridge "ranges" property should be offset from
the BAR address and not the beginning of the address space (similar as to how
the "assigned-addresses" property is generated). This fixes EBus enumeration
under FreeBSD SPARC64.
