BSPs.
The original ARM architecture wide cache_.h is changed to dummy version
for targets not implementing/enablig cache at all.
The ARM targets equipped by cache should include
appropriate implementation.
Next options are available for now
c/src/lib/libbsp/arm/shared/armv467ar-basic-cache/cache_.h
basic ARM cache integrated on the CPU core directly
which requires only CP15 oparations
c/src/lib/libbsp/arm/shared/arm-l2c-310/cache_.h
support for case where ARM L2C-310 cache controller
is used. It is accessible as mmaped peripheral.
c/src/lib/libbsp/arm/shared/armv7m/include/cache_.h
Cortex-M specific cache support
Updates #2782
Updates #2783

This is necessary to add tests that use the cache manager. For example
to get better estimates of worst-case timings.

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.

This BSP shares code with the gp32 and needed to include the
new bspidle.c file.

PR 1917/bsps
* Makefile.am: Modifications to add dynamic tables for libchip serial
drivers.
|
|
|
|
| |
* Makefile.am, preinstall.am: Added generic interrupt support modules.
|
| |
|
|
|
|
|
| |
* Makefile.am, configure.ac: Add Skyeye reset device.
* startup/bspreset.c: New file.
|
|
|
|
|
| |
* Makefile.am: Eliminate bsp.am. Build startup files as side-effect
of building libbspstart.a, using automake-rules.
|
|
|
|
| |
* Makefile.am: Eliminate *_SOURCES.
|
|
|
|
|
| |
* Makefile.am: Move noinst_LIBRARIES = libbsp.a before its
components.
|
|
|
|
| |
* Makefile.am: Remove noinst_PROGRAMS (Unused).
|
|
|
|
| |
* Makefile.am: Cleanup ../../shared/include/bootcard.h handling.
|
|
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, include/bspopts.h.in: 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.
|
|
|
|
|
| |
* Makefile.am, startup/linkcmds: Use top level shared
bsp_get_work_area() implementation.
|
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, include/bspopts.h.in: Split out
bsp_get_work_area() into its own file and user BSP Framework to
perform more initialization. Use same shared implementation as
edb7312 and csb336.
|
|
|
|
|
| |
* Makefile.am: No BSP should use exit.c as a file name. exit() is POSIX
routine.
|
|
|
|
| |
* Makefile.am, preinstall.am: Need tm27.h
|
|
|
|
| |
* Makefile.am: Rework to avoid .rel files.
|
|
|
|
| |
* Makefile.am: Use shared bsp_predriver_hook.
|
|
* ChangeLog, Makefile.am, README, bsp_specs, configure.ac,
preinstall.am, include/bsp.h, include/bspopts.h.in, startup/linkcmds,
startup/memmap.c: New files.
