[PATCH v1 0/8] AArch64 port and BSPs

[Kinsey Moore]

This patch set includes changes to move several required drivers
into bsps/shared so that they can be used by both AArch32(known in RTEMS
as "arm") and AArch64 as well as possibly other future architectures.
The changes made in breaking out these drivers have been tested on 10 or
so affected BSPs under both the old autotools build system and the new
waf build system.

In addition to the AArch64 port itself, this patch set includes a pair
of sample BSPs that run on QEMU and demonstrate use of the two available
multilib variants: lp64 and ilp32. These BSPs are only configurable
under the waf build system. The port and these BSPs do not currently
support SMP, even though there is some SMP-related code currently in
place.

Look for related patch sets for rtems-doc and rtems-tools following
shortly.
