Compatibility Concerns

#8827 arch/nrf52: nvmc and flash should depends on ALLOW_BSD_COMPONENTS=y

Users using nvmc and flash must allow BSD components (CONFIG_ALLOW_BSD_COMPONENTS=y).

#8992 stm32: Remove GPIO_{SPEED MODE}_xxx and provide a legacy path for lazy migration

All boards board.h should be migrated using tools/stm32_pinmap_tool.py `tools/stm32_pinmap_tool.py –pinmap arch/arm/src/stm32h7/hardware/stm32h7x3xx_pinmap_legacy.h –addall –suffix _0 –report /include/board.h it will output 2 sections that should be used to update the board.h.

#9527 sched/tls: remove PTHREAD_CLEANUP from Kconfig

use PTHREAD_CLEANUP_STACKSIZE to enable or disable interfaces pthread_cleanup_push() and pthread_cleanup_pop(). Same as TLS_TASK_NELEM - It is no need to use two variables. Make the reserved entries more explicit

#8985 drivers/pipe: make pipe and named pipe (mkfifo) POSIX-compliant (blocking open)

It would be a possible breaking change if any application was written specifically to expect an open for write-only (and O_NONBLOCK cleared, of course) to be non-blocking even if there are no readers. Being able to port POSIX-compliant applications that expect open to block when opening for write-only with no readers would enhance NuttX’s objective of “to achieve a high degree of standards compliance. The primary governing standards are POSIX and ANSI standards”. That is the case for RTP Tools, for instance.
