[Qemu-devel] [PATCH 0/3] xilinx: Speed up the build

[Andreas Färber]

Hello Edgar and Peter,

With the Makefile refactoring applied now, here's the Makefile improvements
for MicroBlaze I mentioned.

All Xilinx devices that are used for more than one softmmu are compiled once
in libhw32. Actually some also in libhw64 due to ppc440 being compiled into
ppc64, but we can fix that in a second step via Alex' ppc-next, we're already
down from thrice to twice.

The middle patch is extracted from Blue's logging refactoring.

Please test and apply. Your s3adp1800 and virtel_ml507 test images complain
both with and without patches about not finding "eth0". Selftest completes ok
except for not finding /usr/bin/sha1test on ppc440.

xilinx_ethlite.c uses tswap32(). Have you ever tested this device to work on
microblazeel? I wonder if we could change the device from DEVICE_NATIVE_ENDIAN
to DEVICE_BIG_ENDIAN and in place of tswap32() use a bswap32() conditional on
HOST_WORDS_BIGENDIAN so that it becomes independent of the target, too?

Instead of adding random devices to hw/microblaze/Makefile.objs in new series,
they should be added to hw/Makefile.objs with appropriate CONFIG_* options set
in default-configs/microblaze[el]-softmmu.mak as demonstrated here, easy to do
and also ensures that the appropriate poisoning is applied.

Regards,
Andreas
