By default, allocate the IDLE task storage areas from the RTEMS Workspace.
This avoids having to estimate the thread-local storage size in the default
configuration.
Add the application configuration option CONFIGURE_IDLE_TASK_STORAGE_SIZE to
request a static allocation of the task storage area for IDLE tasks.
Update #3835.
Update #4524.
Add the INTERNAL_ERROR_IDLE_THREAD_CREATE_FAILED fatal error in case the
creation of an idle thread fails. This may happen due to a failing create
extension provided by the application.
Place this member placed directly after the end of the common block so that
the structure offsets are as small as possible. This helps on instruction
set architectures with a very limited range for intermediate values. For
example, see the __aeabi_read_tp() implementation for ARM Thumb-1.
Update #3835.
Allow the IDLE stack allocator to change the stack size. This can be
used by applications with a very dynamic thread-local storage size to
adjust the thread storage area of the IDLE tasks dynamically.
Update #4524.
- Add support to get the parent address and size cells
- Provide support to get a reg prop address map
- Change getting a set of properties to uintptr_t
- Improve the debug mode of the ls command to print all props
Closes#4729
This patch adds new Raspberry pi 4B AArch64 BSP to the RTEMS Family. Currently
only LP64 ABI is supported. ILP32 is not supported. RAM starts from 0x80000 in
64Bit kernel mode and MMU from 0x0. All Raspberrypi Pi 4B models and Raspberry
Pi 400 are supported. All the IRQs are similiar to the older Raspberry pi 2 ARM
BSP.
Raspberry Pi 4B has 2 types of UARTs. Only PL011 serial is supported currently.
Mini-UART is not supported. Mini-UART is default UART on the board so it needs
to be disabled by adding "dtoverlay=disable-bt" to the config.txt. No support
for additional 4 PL011-UARTs on the board.
The raspberrypi.h includes many of the address required for the future
development of the RPi 4B BSP. This includes peripherals, ARM Timer, VideoCore
Timer, Watchdog, Mailbox, AUX, FIQs and IRQs.
The second allocation check was mistakenly rechecking the first
allocation. It now checks the correct allocation and ensures that names
is not NULL.
Updates #4462
If the bsp is integrated and supported a device tree
blob(dtb) then use dtb instead of using it from
the U-Boot (BSP_START_COPY_FDT_FROM_U_BOOT=False).
The Microchip PolarFire SoC support is implemented as a
riscv BSP variant to boot with any individual hart(cpu core)
or SMP based on the boot HARTID configurable and support
components are 4 CPU Cores (U54), Interrupt controller (PLIC),
Timer (CLINT), UART.
Add the basic Microchip PolarFire SoC device tree source and blob
The mpfs-dtb.h is generated by the bin2hex
https://github.com/padmaraob/bin2hex
1.Compile and build the bin2hex.c
$ gcc -o bin2hex bin2hex.c
2.Generate the mpfs.dtb from the mpfs.dts
$ dtc -O dtb -o mpfs.dtb mpfs.dts
3.Generate the mpfs-dtb.h Header file from the mpfs.dtb.
$ ./bin2hex mpfs.dtb
There is not just big-endian on ARM. We have two variants BE32
(obsolete) and BE8. The Cortex-R5F processor supports only BE8,
however, some TMS570 variants are BE32 internally. In GCC 8 and later,
the --be8 option is passed to the linker based on the selected
architecture or CPU. Use BE32 by default for the TMS570 BSP.
In GCC, see:

[arm] Clean up generation of BE8 format images.
Note: Resending after learning how to use git send-email, please disregard previous message.
This fixes the riscv fe310 console driver fe310_uart_read function. The function
reads the RX status/data register to check if data is available, but discards
the data and reads it a seconds time.
Also cleared the interrupt enable bit in the first_open function.

All CPU ports used the same _CPU_Counter_difference() implementation. Remove
this CPU port interface and mandate a monotonically increasing CPU counter.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
