From: tbm@cyrius.com (Martin Michlmayr) Date: Sun, 13 Jun 2010 19:37:18 +0100 Subject: [PATCH] Kirkwood: Add MPP44 (board ID) on TS-219 Message-ID: <20100613183718.GA6929@jirafa.cyrius.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org MPP44 can be used to differentiate between one-bay (TS-11x) and two-bay (TS-21x) devices. According to an engineer from QNAP, the setting of MPP44 depends on the firmware rather than hardware. Presumably, this means that you could fake the MPP44 value by changing the boot loader.
