Subject: RISC-V: virt: This is a "sifive,test1" test finisher
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9c0fb20c4bd50a99c3c6f6d515e05eaf8dd87fa4;p=qemu.git

RISC-V: virt: This is a "sifive,test1" test finisher

The test finisher implements the reset command, which means it's a
"sifive,test1" device.  This is a backwards compatible change, so it's
also a "sifive,test0" device.  I copied the odd idiom for adding a
two-string compatible field from the ARM virt board.
