2007-06-21Blackfin arch: Clean up trace buffer handling, No major functional changes.Robin Getz9-43/+97
Turns on trace earlier, so crashes at kernel start should print out a trace, making things easier to debug. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <michael.frysinger@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
2007-07-12Blackfin arch: Start untangling the CPLB handling code.Bernd Schmidt7-507/+528
- 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.

2007-06-21Blackfin arch: defines and provides entry points for certain user space functions at fixed addressesBernd Schmidt9-3/+261
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.
