[Qemu-devel] [PATCH v3 5/6] tests/acceptance: Add test_sh4_r2d in BootLinuxConsole

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Similar to the test_x86_64_pc test, this boots a Linux kernel on a
R2D board (SH4 little-endian) and verify the serial is working.

This test requires the dpkg-deb tool (apt/dnf install dpkg) to
extract the kernel from the Debian package.

Note, due to a problem with the serial on this machine, this test
is currently disabled.
