* Blackfin arch: defines and provides entry points for certain user space ↵Bernd Schmidt2007-06-20
| | | | | | | | | | | | | | | | | | functions at fixed addresses This patch defines (and provides) entry points for certain user space functions at fixed addresses. The Blackfin has no usable atomic instructions, but we can ensure that these code sequences appear atomic from a user space point of view by detecting when we're in the process of executing them during the interrupt handler return path. This allows much more efficient pthread lock implementations than the bfin_spinlock syscall we're currently using. Also provided is a small sys_rt_sigreturn stub which can be used by the signal handler setup code. The signal.c part will be committed separately.

* Blackfin arch: initial supporting for BF548-EZKITRoy Huang2007-07-12
| | | | | | | | | | | | | | | | | 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.
