There were some problems in the math calculating RAM length and NOCACHE
origin location. These have been resolved in this patch allowing RTEMS
RAM space to be relocated above 0xfe00000 to better accomodate other
elements in the system.
Add directives to get and set the priority of an interrupt vector.
Implement the directives for the following BSP families:
* arm/lpc24xx
* arm/lpc32xx
* powerpc/mpc55xxevb
* powerpc/qoriq
Implement the directives for the following interrupt controllers:
* GICv2 and GICv3 (arm and aarch64)
* NVIC (arm)
* PLIC (riscv)
Update #5002.
The clock from the ARM timer is derived from the system clock. This clock can
change dynamically e.g. if the system goes into reduced power or in low power
mode. Thus the clock speed adapts to the overall system performance
capabilities. For accurate timing it is recommended to use the system timers.
if BSP_CLOCK_USE_SYSTEMTIMER = 1, use the System Timer, otherwise use the ARM
Timer.
Make the clock driver parameters configurable. Use the maximum counter
frequency to get the best time resolution. Decouple the CPU counter from the
timecounter. Make the tick catch up handling more robust. Add a validation
test for the tick catch up.
Replace the BSP_CONSOLE_MINOR BSP option for the Xilinx Zynq BSPs with the new
BSP option ZYNQ_UART_KERNEL_IO_BASE_ADDR. Move the kernel I/O support to a
shared file.
This adds a test to very that remounting a completely used, but empty
NOR JFFS2 filesystem is possible. Previously, this triggered an edge
condition in the JFFS2 scan code that prevented remount of a correctly
formed and uncorrupted filesystem.
The RAM origin had an unnecessary alignment requirement and the RAM
lenght had a reference that couldn't possibly be used. This removes
those obsolete option specifiers.
When the switch to waf occurred, the SMP support in i386 was left out
causing it to accumulate a minor amount of cruft. This enables SMP for
the i386 BSPs that support it and updates them for the API drift that
has occurred since the change.
This enables the VME support for the MVME2500. Note that the PCIe
support from libbsd is used. So you need the related libbsd patches for
this to work.
If the drivers in libbsd are not enabled, the linker should not pick up
anything from this patch.
Remove obsolete tms570ls3137_hdk_with_loader BSP variant. With the new
memory origin/size build options this variant is no longer required.
Update #4982.
