From 24a07a124198153540f8f43d9e91d16227aba66e Mon Sep 17 00:00:00 2001 From: Roy Huang Date: Thu, 12 Jul 2007 22:41:45 +0800 Subject: 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.
