The i.MX28 GPMI controller is a flexible interface NAND Flash controller with 8-bit data width, up to
50MB/s I/O speed and individual chip select.
It supports normal timing mode, using two Flash clock cycles for one access of RE and WE. AC timings
are provided as multiplications of the clock cycle and fixed delay.
