Describes the shape of the flash configuration header that the Boot ROM expects to find at offset 0x0400 in the flash memory connected to FlexSPI0, if booting from that device.

The board support package for a board that boots from flash memory on FlexSPI0 should arrange for a suitable value of this type to be placed at 0x0400 in the flash image (0x08000400 if the Flash will be memory mapped) and then the on-chip Boot ROM will retrieve it during boot.

See i.MX RT500 Reference Manual section 18.6.1.2: FlexSPI NOR Configuration Block(FCB).
