Roy Huang 24a07a1241 Blackfin arch: initial supporting for BF548-EZKIT 
The ADSP-BF54x was specifically designed to meet the needs of convergent multimedia
applications where system performance and cost are essential ingredients. The
integration of multimedia, human interface, and connectivity peripherals combined
with increased system bandwidth and on-chip memory provides customers a platform to
design the most demanding applications.

Since now, ADSP-BF54x will be supported in the Linux kernel and bunch of related drivers
such as USB OTG, ATAPI, NAND flash controller, LCD framebuffer, sound, touch screen will
be submitted later.

Please enjoy the show.
