From: Tero Kristo <t-kristo@ti.com> To: <linux-omap@vger.kernel.org>, <tony@atomide.com> Cc: <s-anna@ti.com>, <linux-arm-kernel@lists.infradead.org> Subject: [PATCH 14/17] ARM: dts: beagle-x15-common: Add CMA pools and enable IPU & DSP rprocs Date: Fri, 24 Apr 2020 18:12:41 +0300 [thread overview] Message-ID: <20200424151244.3225-15-t-kristo@ti.com> (raw) In-Reply-To: <20200424151244.3225-1-t-kristo@ti.com> From: Suman Anna <s-anna@ti.com> The CMA reserved memory nodes have been added for all the IPU and DSP remoteproc devices on all the AM57xx BeagleBoard-X15 boards. These nodes are assigned to the respective rproc device nodes, and all the IPU and DSP remote processors are enabled for all these boards. The current CMA pools and sizes are defined statically for each device. The addresses chosen are the same as the respective processors on the DRA7 EVM board to maintain firmware compatibility between the two boards. The CMA pools and sizes are defined using 64-bit values to support LPAE. The starting addresses are fixed to meet current dependencies on the remote processor firmwares, and this will go away when the remote-side code has been improved to gather this information runtime during its initialization. An associated pair of the rproc node and its CMA node can be disabled later on if there is no use-case defined to use that remote processor.
