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.
The "powerpc/shared/console" code has the start-up console value fixed
at 9600 baud. This changes the hard-wired constant "9600" in the code
to the configuration setting "BSP_CONSOLE_BAUD" and adds configuration
support in both the "waf" and the legacy configuration systems.
Note that the VME BSPs beatnik, mvme3100, and mve5100 can be improved
by adding a "mvmexxxx" BSP family. This configuration change, as well
as future configuration changes, could then be made in a "grp.yml" file.
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.
This breaks AArch32-specific portions of the ARM GPT driver into their
own file so that the generic code can be moved for reuse by other
architectures.
start16.S is now only used for SMP configurations to start the
application processors.
This commit removes all unnecessary parts for this job,
i.e. video conssole initalisation, A20 gate activation
and all non-AP related code.
Update #3335
The BSP tried to get the size of the SDRAM based on the revision code.
Unfortunately the code had some bugs so that the default size has been
used. Beneath that the MMU table hasn't been adapted.
This patch queries the SDRAM size via a special VC Mailbox call instead.
For the MMU adaption a simmilar method to the one in the imx BSP is
used.
The small page MMU support reduces the granularity for memory settings
through the MMU from 1MiB sections to 4KiB small pages.
Enable it by default on the realview_pbx_a9_qemu BSP.
LLVM/LLD does not support STARTUP and ALIGN_WITH_INPUT directives that
GNU LD support. INPUT and ALIGN(8) are supported by LLVM/LLD and can
replace the unsupported STARTUP/ALIGN_WITH_INPUT directives.
The commit conditionally adds the supported directive that linkers
can understand depending on the toolchain used to compile RTEMS
i.e., clang or gcc. Clang is assumed to use LLD by default.
