HBMC controller on TI K3 SoC provides MMIO access to HyperFlash similar to legacy Parallel CFI NOR flashes. Therefore alias HyperFlash bootmode to NOR boot to enable SPL to load next stage using NOR boot flow.

On J7200 SoC OSPI and HypeFlash are muxed at HW level and only one of them can be used at any time. J7200 EVM has both HyperFlash and OSPI flash on board. There is a user switch (SW3.1) that can be toggled to select OSPI flash vs HyperFlash. Read the state of this switch via wkup_gpio0_6 line and fixup the DT nodes to select OSPI vs HyperFlash
