[PATCH v7 0/5] build upstream qemu and seabios by default

[Stefano Stabellini <Stefano.Stabellini@eu.citrix.com>]

Hi all,
this is the sixth version of the patch series to introduce upstream qemu
and seabios in the xen-unstable build system.


Changes to v6:

- add "set -e" to git-checkout.sh;

- add argument count check to git-checkout.sh;

- remove spurious semicolons in git-checkout.sh.


Changes to v5:

- use $GIT in git-checkout.sh;

- add an http mirror for seabios;

- use $(LIBEXEC) to configure upstream qemu;

- append a patch for libxenlight to find the upstream qemu binary under
$(LIBEXEC).


Changes to v4:

- remove an obsolete comment;

- use /bin/sh to execute git-checkout.sh rathen than /bin/bash.


Changes to v3:

- reduce the scope of git-checkout.sh, now it only does what the name
says; calling "configure" is responsibility of the caller. As a result
of this change, the build still works when the user specifies a local
directory in the CONFIG_QEMU environmental variable;

- use a more official qemu repository hosted on xenbits;

- use a changeset as QEMU_UPSTREAM_TAG rather than a branch name.



Changes to v2:

- move tools/git-checkout.sh to scripts/git-checkout.sh;

- use git-checkout.sh for seabios;

- improve seabios integration with tools/firmware make system;

- add qemu-xen-traditional, qemu-xen and seabios dir entries to
.hgignore.



Changes to v1:

- always build upstream qemu and seabios, rather than introducing them
as an option.


Cheers,

Stefano
