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.

|
|
|
|
|
| |
* Makefile.am, configure.ac, console/uarts.c: Add initial support for
Kit637 version of CSB637.
* README.kit637_v6, make/custom/kit637_v6.cfg: New files.

* startup/linkcmds.csb337: New (Renamed from linkcmds).
* Makefile.am: Rework linkcmds handling.
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, console/uarts.c: Add console device that
uses MicroMonitor to do actual input and output. This driver should
work on any board that uses MicroMonitor.
|
|
|
|
|
| |
* Makefile.am, preinstall.am: Make an RTEMS specific umon.h wrapper
include file.
|
|
|
|
| |
* Makefile.am: Re-add basic console code.
|
|
|
|
| |
* Makefile.am: Add MicroMonitor support.
|
|
|
|
|
| |
* Makefile.am, preinstall.am: Add MicroMonitor support.
* startup/umonsupp.c: New file.

|
|
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, preinstall.am, console/uarts.c,
include/bsp.h, startup/memmap.c: Add support for /dev/fbcons which is
a console type output only device to print to the LCD screen. The
video controller (SED) and fonts are copied from MicroMonitor and
proper attribution is made in those files and confirmed by Ed Sutter.
* console/fbcons.c, console/font8x16.h, console/sed1356.c,
console/sed1356_16bit.h, include/sed1356.h: New files.

startup/memmap.c: Add csb637 as alias and variant.
* startup/linkcmds.csb637: New file.
|
|
|
|
|
| |
* Makefile.am, preinstall.am: Use shared tm27.h stub.
* include/tm27.h: Removed.
|
|
|
|
|
| |
* 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: Cleanup ../../shared/include/bootcard.h handling.
|
|
|
|
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, startup/bspstart.c: 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/bspreset.c: New file.
* startup/bspclean.c: Removed.
|
|
|
|
|
| |
* Makefile.am, startup/linkcmds: Use top level shared
bsp_get_work_area() implementation.
|
|
|
|
|
|
| |
* Makefile.am, configure.ac, startup/bspclean.c, startup/bspstart.c:
Now support bsp_get_work_area() and used shared implementation of it
and bsp_pretasking_hook.
|
|
|
|
|
|
|
| |
* Makefile.am: No BSP should use exit.c as a file name. exit() is POSIX
routine.
* startup/bspclean.c: New file.
* startup/exit.c: Removed.
|
|
|
|
| |
* Makefile.am: Rework to avoid .rel files.
|

|
|
|
|
|
|
|
| |
* Makefile.am, startup/bspstart.c: Moved most of the remaining CPU
Table fields to the Configuration Table. This included
pretasking_hook, predriver_hook, postdriver_hook, idle_task,
do_zero_of_workspace, extra_mpci_receive_server_stack,
stack_allocate_hook, and stack_free_hook. As a side-effect of this
effort some multiprocessing code was made conditional and some style
clean up occurred.
|
|
|
|
|
| |
* Makefile.am: Add abort.rel since it is now in the BSP shared source,
not in score/cpu.
|
|
|
|
|
| |
* Makefile.am: Merge c_rtems_main() into boot_card(). This eliminated a
file and simplified initialization.
|
|
|
|
| |
* Makefile.am: Remove superfluous -DASM.
|
| |
|
| |
|
|
|
|
