* [#8166](https://github.com/apache/nuttx/pull/8166) ESP32: Enable the allocation of Userspace heap exclusively in SPI RAM under Flat mode 

	Breaking change: ESP32_SPIRAM no longer auto selects XTENSA_IMEM_USE_SEPARATE_HEAP.
	XTENSA_IMEM_USE_SEPARATE_HEAP is now selected by ESP32_IMM_HEAP, which in turn is not enabled by default.

	Drivers that previously relied on XTENSA_IMEM_USE_SEPARATE_HEAP now bring in ESP32_IMM_HEAP if ESP32_SPIRAM is also selected, with the notable exception from ESP32_WIFI.

	ESP32_WIFI previously used XTENSA_IMEM_USE_SEPARATE_HEAP for allocating dynamic data into Internal RAM via a specific API. 
	With this PR, there is now an alternative approach using MM_KERNEL_HEAP. So it is up to the user to either select ESP32_IMM_HEAP or MM_KERNEL_HEAP.
	In order to keep the current behavior, custom board users shall select ESP32_IMM_HEAP on Kconfig.  

* [#7525](https://github.com/apache/nuttx/pull/7525) Improvements in TCP connections allocation. 

	This is an attempt to fix the issues reported in #6960:

    Only a single connection is allocated, the one actually needed.
    In tcp_free() the connection is actually deallocated, instead of leaving it existing forever in the list.

	This is only the first step, possibly with more to come (list of pre-allocated connections, maximum connections limit etc).

	For the moment, this PR handles only TCP, till we determine all the details.
	Then the fix will be copied to all other connections that use similar logic.

* [#8691](https://github.com/apache/nuttx/pull/8691) drivers/serial: Echo input in driver layer 
* [#8846](https://github.com/apache/nuttx/pull/8846) drivers/pty: Echo input by default

	Align the pty behavior to linux/bsd,
	Also fix the ECHO issue with microadb after #8691.
	adb shell will echo normally with this patch.

* [#8235](https://github.com/apache/nuttx/pull/8235) board: Pass the assertion expression to board_crashdump too

* [#8717](https://github.com/apache/nuttx/pull/8717) arch/armv8-m: DSP extension is optional 
	The DSP extension is optional for armv8-m cores, so it should be explicitly set by chip configuration.
	Otherwise this can lead to hard to debug hardfaults for cores that do not support DSP.
	Breaking change for out-of-tree armv8-m chips.

* [#8378](https://github.com/apache/nuttx/pull/8378) tools/makefile: silent all compile output 
	In order to make compilation warnings and errors easier to be found out,
	this commit will disable the printing of the compilation process as much
	as possible, and also if you want to restore the log information of the
	compilation process, please enable verbose build on command line:

	$ make V=0
	OR
	$ make V=1

	| V=0:   Exit silent mode
	| V=1,2: Enable echo of commands
	| V=2:   Enable bug/verbose options in tools and scripts

* [#8623](https://github.com/apache/nuttx/pull/#8623) include/signal.h:Expanding SIGNAL to be consistent with Linux 
	build breaks if CONFIG_SCHED_HAS_PARENT is not defined because SIGCHLD will collide with the new values.
