AArch64 Bootstrap Stage2 Notes
Here's what changed from f17 to get aarch64 to bootstrap (using the rootfs built in stage1) in build order as determined by dependencies in the make file fragments. Stage1 details are here.
A copy of the current state of the stage2 rootfs can be retrieved from:
$ git clone http://fedorapeople.org/groups/armv8/rootfs.git
This rootfs can be used directly as an NFS root mount point if you have access to either the ARM FAST model or the ARM Foundation model (see http://www.arm.com/fvp); details for doing so are in Using ARMv8 Bootstrap Root FS via NFS root. With some preparation, you can also turn this set of files into a rootfs disk image that can be used with the ARM Foundation model (see ARMv8 using Fedora17 Bootstrap Image and ARM Foundation Model).
NB: just as with stage1 ( AArch64 Bootstrap Stage1 Notes), the sources used can be found here:
http://fedorapeople.org/groups/armv8/SRPMs
Look in the subdirectories f17/changed (which should have been copied into SRPMlocal in your copy of the bootstrap directory), and in the subdirectory f17/unchanged (which should be copied into SRPMs in your bootstrap directory).
To work with the stage2 rootfs, follow the instructions pointed to above and boot a model and either an NFS root or a disk image. Once you have booted into the rootfs, however, continuing the stage2 build is pretty straightforward:
# cd /stage2 # ./stage2
You will be running in a BusyBox environment at that point, and you do have most basic commands, and basic job control.
cpio
Source: cpio-2.11-6.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Patched use of gnulib to remove deprecated use of gets(). Added patches to cpio.spec.

Patched aarch64 support to config.sub and config.guess. Added patch to ncurses.spec.
m4
Source: m4-1.4.16-3.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Patched use of gnulib to remove deprecated use of gets(). Added patches to m4.spec.
flex
Source: flex-2.5.35-14.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to flex.spec.
bison
Source: bison-2.5-3.fc17.aarch.src.rpm
Patched aarch64 support to config.sub and config.guess. Patched use of gnulib to remove deprecated use of gets(). Added patches to bison.spec.
readline
Source: readline-6.2-4.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to readline.spec.
texinfo
Source: texinfo-4.13a-16.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to texinfo.spec.
gdb
Source: gdb-7.5.0.20120926-25.fc17.aarch64.src.rpm
Started with 7.5 version of the source (from f18), since the upstream patch uses ptrace and as such it did not apply to the 7.4 version; several functions ended up rewritten or replaced so that in some cases the upstream patch was referring to code that did not exist in 7.4.
Further, the upstream patch was incomplete. While it got most parts, it made the assumption that the subdirectories bfd/, opcodes/, and include/ had all been updated to reflect the latest binutils for aarch64; this was not the case for f17. So, merged each of those directories with the binutils files (in the same directories) from stage1 in order to add support for aarch64 everywhere it was needed.
Patched aarch64 support into config.sub and config.guess. Added all of these patches to gdb.spec.
Still FTBFS, but have continued on to other packages.
libtool
Source: libtool-2.4.2-3.1.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to libtool.spec.
gdbm
Source: gdbm-1.10-2.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to gdbm.spec.
db4
Source: db4-4.8.30-10.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to db4.spec.
perl
Source: perl-5.14.2-215.fc17.aarch64.src.rpm
Patched the definition of Perl_repeatcpy() in util.c so that the last argument was consistently defined; it had been type IV (which defaulted to 64-bit on aarch64) in the definition, but type I32 (32-bit) in the declaration. Added patch to perl.spec.
curl
Source: curl-7.24.0-5.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to curl.spec.
nspr
Source: nspr-4.9.2-1.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to nspr.spec.
Patched _linux.cfg and _linux.h in pr/include/md to add in the aarch64 architecture; cloned the definitions used from ia64, another LP64 platform. Added patch to nspr.spec.
pcre
Source: pcre-8.21-6.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to pcre.spec.
Changed the recipe.d make snippet so that documentation is not installed. When running make install, the command lines generated (e.g., when installing the HTML files or man pages) are quite long and will sometimes get cut in odd places causing the make to fail, but only for the documentation; everything else has built properly.
gettext
Source: gettext-0.18.1.1-14.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to gettext.spec.
Still FTBFS for now; it looks like an extraneous usage of gets() is the issue.
popt
Source: popt-1.13-10.fc17.aarch64.src.rpm
Patched aarch64 support to config.sub and config.guess. Added patch to popt.spec.
This needs gettext to complete before it compiles. State unknown right now.
chkconfig
This requires gettext and popt to be built first but did not have them as "#requires" in the recipe.d file; added them.
