└─>Enable GPMC debug output and skip reset of GPMC during init
In linux kernel since version 4.1 (release Date: 2015-06-21)
Enables verbose debugging mostly to decode the bootloader provided
timings. To preserve the bootloader provided timings, the reset
of GPMC is skipped during init. Enable this during development to
configure devices connected to the GPMC bus.
NOTE: In addition to matching the register setup with the bootloader
you also need to match the GPMC FCLK frequency used by the
bootloader or else the GPMC timings won't be identical with the
bootloader timings.
