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


From: Ralf Baechle
Subject: [Qemu-devel] [PATCH 2/3] Add i8259 PIT to MIPS
Date: Mon, 15 Aug 2005 09:56:31 +0100
User-agent: Mutt/1.4.2.1i

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.
