2007-07-25Blackfin arch: revise anomaly handling by basing things on the compiler not ↵Mike Frysinger
the kconfig defines revise anomaly handling by basing things on the compiler not the kconfig defines, so the header is stable and usable outside of the kernel. This also allows us to move some code from preprocessing to compiling (gcc culls dead code) which should help with code quality (readability, catch minor bugs, etc...).

When compiling the Blackfin kernel, checksyscalls.pl will report lots of missing syscalls warnings.

2007-06-21Blackfin arch: defines and provides entry points for certain user space ↵Bernd Schmidt
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.

2007-07-12Blackfin arch: initial supporting for BF548-EZKITRoy Huang
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.
