* bsps: Fix TLS support in linker command filesSebastian Huber2014-04-221-1/+3
| | | | | The TLS section symbols had wrong values in case of an empty TLS data section and a nonempty TLS BSS section.
* powerpc: Change interrupt disable implemetationSebastian Huber2014-02-191-1/+0
| | | | | | | | | | | | Instead of SPRG0 (= special purpose register 272) use the new global symbol _PPC_INTERRUPT_DISABLE_MASK to store the interrupt disable mask. The benefit is that it is now possible to disable interrupts without further run-time initialization in boot_card(). At least on Freescale e500 cores this leads also to a faster execution since the mfmsr and mfspr instruction require four cycles to complete. The instructions to load the mask value can execute while the mfmsr is in progress.
* score: Add CPU counter supportSebastian Huber2014-02-141-0/+3
| | | | | | | | | Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-112-4/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

| | | | | | | | | * Makefile.am, configure.ac: Use standardized bsp_cleanup() which can optionally print a message, poll for user to press key, and call bsp_reset(). Using this eliminates the various bsp_cleanup() implementations which had their own implementation and variety of string constants. * startup/bspclean.c: Removed.
