[Qemu-devel] [PATCH 2/3] Add i8259 PIT to MIPS

[Ralf Baechle <ralf@linux-mips.org>]

Add i8259 PIT to the MIPS configuration.  Not that the counter / compare
interrupt isn't nicer but the i8259 unfortunately a common peripheral in
MIPS systems and so it's probably a piece of code want just in case.
