The devfg driver loads the PL with a bitfile image. The driver can also
support scrubbing.
These drivers are from Patrick Gauvin <pggauvin at gmail.com> and a thread
on the devel list: https://lists.rtems.org/pipermail/devel/2017-May/017705.html
When using QEMU configurations that support SMP for Zynq7000 systems,
the second core is started at the same time as the first core instead of
waiting for an event to trigger a check for the value at 0xfffffff0
before jumping into RTEMS code. This makes the erroneously started core
wait as expected and prevents prefetch and data aborts from occurring
before the MMU has been properly configured. This was recently exposed
by cleanup done to the ARM GICv2 driver that removed some delays which
were allowing this to operate normally.
The general optclkbootcpu option is targeted at all ARM QEMU BSPs, but
is not actually linked in to the build tree. This links it in as
expected and removes a redundant and stale copy in the realview PBX BSP.
The RT_TSW_OK field is set to 1 if there was no error. The Message Error
(ME) field indicates an error and must be set to 0 if there was no error
so the result of tsw&RT_TSW_OK must be negated. It is then left-shifted
to the Messsage Error (ME) bit field of the message information word.
Fix issue CID 1399772
This removes the headers imported from the embeddedsw repository in
favor of a much thinner shim. This also removes the complicated build
system configuration necessary to support use of these headers. The
primary reason for removal is that certain external Xilinx libraries
also require use of these headers and this causes version mismatches and
header conflicts that can be avoided.
- Add support for four new ports, UART2-UART5.
- Add build options to allow console device configuration.
- Segregate device-specific definitions from the device family files. X macros
are used to maintain a single source of truth and have the configuration
done at compile-time
- Add raspberrypi_uart_init() to make it convenient for users to install uart
devices

* 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

This removes the carriage return printed before the shell prompt as it
can cause other output to be overwritten unexpectedly. This was
discovered when using the "cat" shell command on a file whose content
contained no trailing \n\r and was short enough to be entirely swallowed
by the prompt.
The rtime decompression routine does not fully check bounds during the
entirety of the decompression pass and can corrupt memory outside the
decompression buffer if the compressed data is corrupted. This adds the
required check to prevent this failure mode.
Updates #5072
This reverts commit c1aa06dbd2.
Extending the rtems_stack_checker_info like this breaks the existing
visitor API used by rtems_stack_checker_iterate(). After review, using
an information structure contradicts the intention of the reporter to
allow a minimal reporting. Filling up the information structure with
all the details would pull in several dependencies, like
_Thread_Get_name(). The API should be improved to provide the user with
the necessary information from the TCB without having to access members
directly.
This removes the xilinx and lp64 identifiers from the ZynqMP BSPs and
updates those names throughout the build system. The xilinx identifier
is being removed because it is implied by zynqmp and lp64 is being
removed because it is the default for AArch64.
This also renames grp_zu3eg.yml to grp_hardware.yml to more accurately
reflect its purpose.
Updates #5119
Now that minimum.exe is minimum.norun.exe, the tester will not attempt
to run this sample test and will therefore not categorize it as a
failure since it includes no output. BSP-level test configurations for
this test can now be removed since those configurations only existed to
prevent it from being run.
On other targets, the rtems_cache_flush_entire_data() also performs a
clean and invalidate.
This is a workaround for "Answer 68874 - Zynq UltraScale+ MPSoC, APU -
An Eviction Might Overtake A Cache Clean Operation".
