Removed all uses and implementations of set_vector() function across ERC32,
LEON2, and LEON3 BSPs. Replaced with rtems_interrupt_handler_install() and
rtems_interrupt_entry_install().
- Added ERC32_Clear_and_unmask_interrupt() and LEON_Clear_and_unmask_interrupt()
for unmasking logic previously in set_vector().
- Deleted set_vector() definitions and implementations in each BSP.
- Updated related obj.yml files.
- Replaced set_vector() with rtems_interrupt_catch() in shared/gnatcommon.c.
Provide missing GCC atomics helpers as part of BSPs where GCC
does not know how to provide it since the CPU's ISA has no
atomic instructions. The implementation provided in
bsps/shared/atomics/__atomic_test_and_set.c should work
on any single core CPU.
The BSPs that need thie function tend to have older cores. This
is the list of BSPs:
arm - csb336, csb337, csb637, edb7312, gumstix, kit637_v6, lpc24xx_ea,
lpc24xx_ncs_ram, lpc24xx_ncs_rom_ext, lpc24xx_ncs_rom_int,
lpc24xx_plx800_ram, lpc24xx_plx800_rom_int, lpc32xx_mzx,
lpc32xx_mzx_stage_1, lpc32xx_mzx_stage_2, lpc32xx_phycore,
rtl22xx, rtl22xx_t, smdk2410
m68k - av5282, mcf5329
mips - jmr3904
moxie - moxiesim
nios2 - nios2_iss
riscv - grv32i, grv32im, niosvc10lp, noel32im, rv32i, rv32im,
sparc - ut699
The following files will be installed during SPARC/GRLIB builds:
- bsps/include/grlib/apbuart-regs.h
- bsps/include/grlib/gptimer-regs.h
- bsps/include/grlib/irqamp-regs.h
- bsps/sparc/include/grlib/io.h
Fix issue #5231
Merge the timecounter and CPU counter support for the leon3 BSP family.
Remove now unused functions from the CPU counter support of the erc32
and leon3 BSPs.
Update #4954.
Remove the BSP_POWER_DOWN_AT_FATAL_HALT BSP option. Applications should
do the customization of the system termination with an initial fatal
extension.
Merge the "default" and "default-by-variant" attributes. Use an
"enabled-by" expression to select the default value based on the enabled
set. This makes it possible to select default values depending on other
options. For example you could choose memory settings based on whether
RTEMS_SMP is enabled or disabled.
The change was tested by comparing the output of
./waf bspdefaults
before and after the change.
The BSPs provide memory for the separate C Program Heap initialization
via _Memory_Get(). Most BSPs provide exactly one memory area. Only two
BSPs provide more than one memory area (arm/altera-cyclone-v and
bsps/powerpc/mpc55xxevb). Only if more than one memory area is
provided, there is a need to use _Heap_Extend(). Provide two
implementations to initialize the separate C Program Heap and let the
BSP select one of the implementations based on the number of provided
memory areas. This gets rid of a dependency on _Heap_Extend(). It
also avoids dead code sections for most BSPs.
Change licence to BSD-2-Clause according to file history.
Update #3053.
The BSPs provide memory for the workspace initialization via
_Memory_Get(). Most BSPs provide exactly one memory area. Only two
BSPs provide more than one memory area (arm/altera-cyclone-v and
bsps/powerpc/mpc55xxevb). Only if more than one memory area is
provided, there is a need to use _Heap_Extend(). Provide two
implementations to initialize the workspace handler and let the BSP
select one of the implementations based on the number of provided memory
areas. This gets rid of a dependency on _Heap_Extend(). It also avoids
dead code sections for most BSPs.
Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap()
for all unexpected traps. This enables a proper RTEMS fatal error handling
right from the start. Do not rely on the stack and register settings which
caused an unexpected trap. Use the ISR stack of the processor to do the fatal
error handling. Save the full context which caused the trap. Fatal error
handler may use it for error logging.
Unify the _CPU_Exception_frame_print() implementations and move it to cpukit.
Update #4459.
Moves drvmgr_drivers[] from amba.c to a separate file in order
to avoid the dependecy on APBUART/GPTIMER drivers. This has
an effect when user configured not to use timer or uart
in their project.
