System DMA (DMA OCPT1 port)
The frame buffer only supports READ/WRITE/IDLE accesses: an error is
generated in other cases or if the address is incorrect.
The frame buffer only supports 8-, 16-, and 32-bit access in little endian.

The module is clocked up to 100 MHz with the TC2_CK on OCP T2 port.
The frame buffer only supports incrementing burst accesses.
Any invalid access is logged into the OCPT2_ATYPER register within
OMAP3.2. The OCP bus error access corresponds to OCPT2_ATYPER[3]
status bit.
Peripheral Reset
The software must ensure that no access is performed (including DMA
access) while the MPU peripheral reset is asserted. Whenever the
peripheral reset is active, the OCP interface is held in reset.
