The original configuration files and tune fils for arm arch64 are from linaro.
And we rename it to qemuarm64 for consistency.
Consistent to what? All current qemu machines are named after the qemu arch, so
consistent would be 'qemuaarch64'. The 'arm64' moniker is *only* used in the
kernel and that was caused by Linus being grumpy, everything else is 'aarch64'
or 'armv8'
The arm64 name -did- come from Linaro:
http://git.linaro.org/openembedded/meta-linaro.git/tree/HEAD:/meta-aarch64/conf/machine/include
The arch-armv8.inc file (that arch-arm64.inc was based on) is located in the
directly "arm64".
In addition, the tune file that forms the basis of the ARM tunes is called
'arch-arm.inc'. Not arch-aarch32.inc. If you want to rename that, we can
discuss it.. but to match that naming I chose 'arch-arm64.inc'.
(arch-armv8.inc was kept, but only includes the arch-arm64.inc file since there
are no custom optimizations for 'v8' that I can find.)
As far as the machine name goes the original Linaro version, genericarmv8.conf
and genericarmv8b.conf, don't match any of the naming conventions that are
currently used by QEMU BSPs.
Looking at the existing machine names:
qemuarm.conf qemumips64.conf qemumips.conf qemuppc.conf qemux86-64.conf
qemux86.conf
Each of the suffix names used match the Linux kernel arch naming.
So based on that reasoning the generic little endian machine was defined as
qemuarm64.conf.
