32-bit GPIF and SPI boot
I read from some posts that it is possible to enable SPI boot while still using 32-bit GPIF in the application. My understanding is that after booting from SPI flash, the firmware configures the GPIF to be 32-bit, but how about those pins used by the SPI flash? Can those pins be used for other purposes, like UART or GPIO? Thank you.
