Currently generic RISC-V BSPs (riscv/riscv) that start with rv64 and not
rv64*_medany will start at 0x70000000. This adds high maintenance overhead
and deviates from almost all other RISC-V-based OSes and baremetal programs
that start at 0x80000000. Further, testing now has to account for an extra
parameter (medany or not) that doubles the number of BSPs need to be
tested.
This commit defaults all RV64 BSPs to use medany code model to allow starting
all BSPs at 0x80000000. BSPs that require different code models and/or
start addresses are custom and need to add their own entries.
Updates #4775
Since fdt_next_tag() in a public API function all input parameters,
including the fdt blob should not be trusted. It is possible to forge
a blob with invalid property length that will cause integer overflow
during offset calculation. To prevent that, validate the property length
read from the blob before doing calculations.

Correctly calculate the array index and shift value in
_Processor_mask_To_uint32_t(). The bugs had no impact yet since this
function was always called with a zero value for the index in RTEMS.
With the old build system in RTEMS 5 that was possible by just
overwriting BOARD_Sdram_Config and setting a custom
ATSAM_MEMORY_SDRAM_SIZE during building the BSP. In the new build system
that ATSAM_MEMORY_SDRAM_SIZE is set exclusively by the selected SDRAM
chip.
This patch adds the possibility to specify a "custom-0x100000" or
similar as SDRAM type where the number gives the SDRAM size.
A SPI transfer where the Rx or Tx buffer is set to NULL currently
transfers or overwrites data starting from address 0x00000000 via DMA.
This patch changes the DMA setup so that dummy transfers are done.
Just reading / writing to a single location is simpler than changing the
whole logic of the transfer depending on the passed buffers.
Add ref-clock-num identifiers to the device tree to ensure that
interfaces use the correct clocks even when some are not used due to
unconnected MII busses. This also adjusts the default ZynqMP PHY
attachment to RGMII-ID which was the default before device trees were
introduced.

This enables the tracing of interrupt entry/exit events through an
application configuration option. The interrupt processing can be
viewed with Trace Compass using rtems-record-lttng from the RTEMS Tools.
Update #4769.
This fixes build errors seen when building with console interrupts
enabled. A few places were missing bspopts.h includes, and one of the
UART functions was not defined.
Use of malloc implies errno which adds TLS dependencies and prevents use
of this FDT wrapper library in BSP initialization code. This change
makes use of rtems_malloc and rtems_calloc which avoid TLS dependencies.
This changes the ZynqMP device tree parsing over to direct libfdt calls
to avoid inclusion of malloc() in the base BSP which currently causes
sp01 to fail due to unexpected use of TLS space.
In the original implementation, level -1 was unused and all levels could
have block-like descriptors (level 2 block descriptors are called page
descriptors). When support for level -1 page tables was added the
constraint on level -1 block descriptors was not honored. This prevents
block descriptors from being mapped at level -1 since the hardware will
not map them properly.

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.
Use the tm27 support to test a spurious interrupt. This helps to run the
validation test case on targets which have no software interrupt available for
tests (for example riscv/PLIC/CLINT in the SMP configuration).
