Subject: [U-Boot] [PATCH v2 3/6] arm: dts: k3-j721e-mcu-wakeup: Add HyperBus Controller node
Date: Thu, 10 Oct 2019 11:22:04 +0530 [thread overview]
Message-ID: <20191010055207.26831-4-vigneshr@ti.com> (raw)
In-Reply-To: <20191010055207.26831-1-vigneshr@ti.com>
Add DT node for HyperBus Memory Controller in the FSS. On J721e, its not
possible to use OSPI0 and HBMC simultaneously as they are muxed within
the Flash Subsystem hence disable HBMC by default as keep OSPI enabled.
Bootloader will fixup DT when it detects HyperFlash instead of OSPI.
