* It is not granted that we will always access to natually aligned
access. So, before handling endianess do byte-a-byte load using
the appropriate libfdt function to avoid unaligned access issues

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.
Move declarations of bsp_interrupt_get_affinity() and
bsp_interrupt_set_affinity() to <bsp/irq-generic.h>. Canonicalize the
<bsp/irq.h> includes.
Implement bsp_interrupt_get_affinity() and bsp_interrupt_set_affinity() only if
needed (usually RTEMS_SMP).
Provide stub implementations for i386 to fix build errors.
Pass the parameter of the clock interrupt handler to
Clock_driver_support_at_tick() and Clock_driver_timecounter_tick(). This makes
it possible to use the interrupt handler argument in clock drivers.
Use the interrupt handler provided by Clock_driver_support_install_isr() to
avoid local delarations of Clock_isr().
Update #4862.
This patch adds support for the Kendryte K210 RISC-V BSP variant.
The SoC uses the existing Interrupt Controller, Timer, and console UART.
It only needs SoC specific initialization and an embedded device tree binary
similar to the polarfire SoC BSP.
Updates #4876
This patch adds the k210 device tree source and the corresponding
device tree blob encoded in the header which is used for the
embedded device tree blob for the Kendryte K210 BSP variant.
Updates #4876
Use the mtimecmp from the PLIC/CLINT initialization in the clock driver. This
register is defined by the device tree and does not assume a fixed mapping.
In SMP configurations, check that we run on a configured processor. If not,
then there is not much that can be done since we do not have a stack available
for this processor. Just loop forever in this case. Do this in assemlby to
ensure that no stack memory is used.
Low-end configurations may want to have the HTIF support removed.
Enable the option by default. Fix formatting. Fix node validity
checks.
Updates #4779.
This patch changes the license to BSD-2 for all source files where the
copyright is held by Aeroflex Gaisler, Cobham Gaisler, or Gaisler Research.
Some files also includes copyright right statements from OAR and/or
embedded Brains in addition to Gaisler.
Updates #3053.
In SMP configurations, there may be no software interrupt handler
installed when the software interrupt is processed. Add the new
interrupt handler dispatch variant
bsp_interrupt_handler_dispatch_unlikely() for this special case.
This fixes a problem with parsing the FDT compatible property by
replacing the RISCV_CONSOLE_IS_COMPATIBLE macro with calls to
the fdt_stringlist_contains function. The macro only works when
the compatible FDT entry is a single string and not a list of
strings. The new call will compare each item in the string list.
Close#4728.
