This patch updates STM32 H7 HAL source files. The files are taken from two
STM projects from their github.com repositories:
(i)
https://github.com/STMicroelectronics/stm32h7xx_hal_driver.git
The project files are still available under BSD-3 license
and the version/commit used is:
d5fc8d05fc16fa2a2a2f948cf6c6ab39e78358e1
which represents post Release v1.11.1 development tree.
(ii)
https://github.com/STMicroelectronics/cmsis_device_h7.git
The project files were re-licensed from previous BSD-3 to Apache 2.0
license. Fortunately the project does not contain NOTICE file so no need
to do anything special when used in RTEMS.
The project version/commit imported is:
6d5ef249bec5177e0e2a0880ed62df2132874d99
which is code-wise Release v1.10.3 exactly.
The LEON3_IrqCtrl_Adev object is only defined if LEON3_IRQAMP_BASE is
not defined.
The LEON3_Timer_Adev object is only defined if LEON3_GPTIMER_BASE is not
defined.
Close#4850.
The flash configuration is something very board specific. So move the
file to a board specific location. Beneath that, not all controllers and
configurations need the flash config right at the address 0 of the
flash. For example on the i.MXRT11xx, the config has an offset for some
flash types.
The imx-gpio driver used in i.MX and i.MXRT BSPs generates a name based
on a fixed string. The original code only used one digit for the
controller. With the 13 GPIO controllers of the i.MXRT1166, that isn't
enough any more. This patch extends the name to two digits which should
be enough for the next controller generations.
CAVEAT: license change from BSD to Apache2 license!
Explanation:
The imported files come from CMSIS v5 project available on:
https://github.com/ARM-software/CMSIS_5/tree/develop
The files imported are located inside the CMSIS/Core/Include
project sub-directory.
The project does not provide any NOTICE file in its root directory nor
in the directory of the imported files.
The NOTICE file and its usage in the Apache 2 license was/is
so far the only issue mentioned in discussion of RTEMS developers/users
when considering inclusion of the code under Apache 2 license
into the RTEMS project.
Since the CMSIS v5 project is free from this legal hinder, we may freely
use it and update files to the latest version.
Technical: the patch replaces code from 2015 with the latest version
which brings quite a lot of bug fixes and most importantly opens
possibilities to support MCUs based on new ARM cores.
This adds support for the STM32H750B-DK discovery kit. This kit includes
a built-in STLINKv3 debugger which provides a USB serial bridge for
USART3. USART1 is routed to the Arduino header and USART2 is routed to
the STMOD connector. This BSP reuses what would otherwise be duplicated
files from the stm32h747i-disco BSP. Note that system_stm32h7xx.c has
been imported from the STM repository with two minor changes wrapped
with #if __rtems__. This hardware has been tested with hello and ticker.
rtems_task_wake_after takes a parameter in terms of a count of clock
ticks and not a measure in a subunit of seconds. This updates
documentation to reflect that. This also makes obvious the caveat about
the first tick wait not being a whole tick and points the user at a
replacement for better accuracy.
