This is the microcode for the GenBD task and the associated support code. This is a generic task that copy data to/from a hardware FIFO. This is currently locked to 32bits wide access but could be extended as needed. The microcode itself comes directly from the offical API (v2.2) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
