Subject: [RFC 6/8] ARM: OMAP2+: am43: basic dt support
Date: Mon, 18 Feb 2013 12:00:36 +0530	[thread overview]
Message-ID: <64d18c5a07bf7680b8299f3ef98303e60522e738.1361166003.git.afzal@ti.com> (raw)
In-Reply-To: <cover.1361166003.git.afzal@ti.com>

Describe minimal DT boot machine details for AM43 based SoC's. AM43
family of SoC's are ARM Cortex-A9 based with one core in SMP
configuration. Low level debug could be achieved by selecting
DEBUG_AM33XXUART1. To boot AM43 SoC, this change is sufficient w.r.t
Kernel (considering the fact that strictly speaking DT sources does
not classify as a part of Kernel). Here private timer of the one and
only core is being used as clock event (as well as, as time source).
