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. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Reviewed-by: Stefan Roese <sr@denx.de>
