- Move cache initialization to C from assembly.
 - Move anomaly workaround for writing [ID]MEM_CONTROL to assembly, so
   that we don't have to mess around with .align directives in C source.
 - Fix a bug where bfin_write_DMEM_CONTROL would write to IMEM_CONTROL
 - Break out CPLB related code from kernel/setup.c into their own file.
 - Don't define variables in header files, only declare them.

Bernd Schmidt 7adfb58fbd Blackfin arch: defines and provides entry points for certain user space 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.

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.
