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.
