In the meantime, what I know for sure is that we need a PCIe implementation that is able to share drivers/host/* code between arm and arm64 (and possibly other architectures). We had some attempts for more unification between arm64, powerpc, microblaze, mips (http://lkml.indiana.edu/hypermail/linux/kernel/1304.3/00698.html, http://www.linux-mips.org/archives/linux-mips/2013-07/msg00031.html) and work is ongoing. > Now that we are moving from just compiling multiple platforms together > to actually running them, what problems have been run into?

If size becomes an issue, the next step for multi-platform could be compiling as much SoC-related code as possible into loadable modules that can go into initramfs. -- Catalin
