[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.

[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.
