Subject: tests/functional: Test both microblaze s3adsp1800 endianness variants
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6c5477558490cf76dc6d521fe906a2bfbc96ee27;p=thirdparty%2Fqemu.git

tests/functional: Test both microblaze s3adsp1800 endianness variants

Now that the endianness of the petalogix-s3adsp1800 can be configured,
we should test that the cross-endianness also works as expected, thus
test the big endian variant on the little endian target and vice versa.
(based on an original idea from Philippe Mathieu-Daudé)
