Subject: [Qemu-devel] [PULL v2 2/5] target/openrisc: Make coreid and numcores variable
Date: Sat, 21 Oct 2017 07:05:30 +0900	[thread overview]
Message-ID: <20171020220533.29186-3-shorne@gmail.com> (raw)
In-Reply-To: <20171020220533.29186-1-shorne@gmail.com>

Previously coreid and numcores were hard coded as 0 and 1 respectively
as OpenRISC QEMU did not have multicore support.

Multicore support is now being added so these registers need to have
configured values.
