Before any other Make logic can be used, we must immediately build the tools/incdir binary. It will be used as soon as Make.defs is included and will generate errors otherwise.
Remove the other locations in the tools/incdir binary was being build from tools/Makefile.unix and tools/Makefile.win
This is a change suggested by Xiao Xiang in an email thread. Some make variables with depend on forking and shell and running a script to get the value of the variable. Using := we can force the calculation to occur only once. This leads to a small but consistent improvement in build performance.
This change really applies to ALL Make.defs files but is applied only to one here so that it can be thoroughly verified and possbily leveraged to other Make.defs files in the future.
1. If config.c is compiled on any platform other than Cygwin, then the variable wintools is not used.
2. Add more debug output so we can see what is going on in the PR checks.
574b25 broke the internal DMA buffers usage that solved
the following problem: The DMA capable interface does
not know the buffers extent. It calulates it from size.
The user may need to transfer less than a cachline bytes,
but STILL have a DMA cabable buffer. The user is therefore
foreced to transfer more data then needed to "trick" the
DMA cabable function. This is a wast of bus bandwith and
may not work will all devices. The internal buffer, solve
this issue.
stm32h7:stm32_spi review changes
Added sugestion from jlaitine to support RX only.
The use of uint64_t primitive type in NFS structures forces the compiler to align data on an 8-byte boundary.
As a result of this, unwanted gaps being created, which causes NFS to fail. (e.g., nfs_read/initialize the request)
Using nfsuint64 instead of uint64_t fixes this issue.
Block and MTD drivers may be opened and managed as though they were character drivers. But this is really sleight of hand; there is a hidden character driver proxy that mediates the interface to the block and MTD drivers in this case.
fstat(), however, did not account for this. It would report the characteristics of the proxy character driver, not of the underlying block or MTD driver.
This change corrects that. fstat now checks if the character driver is such a proxy and, if so, reports the characteristics of the underlying block or MTD driver, not the proxy character driver.
This is a work in progress, and now only serves as
DMA enabled simplex RX-only mode bus controller

Make it possible to enqueue and receive full buffers of data with
single call, to avoid call overhead when sending / receiving large amounts
of data.
Also make it possible for the slave device to leave received data in the
controller receive buffers and retrieve it from there by polling

sched_releasetcb() will normally free the stack allocated for a task. However, a task with a custom, user-managed stack may be created using nxtask_init() followed by nxtask_activer. If such a custom stack is used then it must not be free in this many or a crash will most likely result.
This chagne addes a flag call TCB_FLAG_CUSTOM_STACK that may be passed in the the pre-allocted TCB to nxtask_init(). This flag is not used internally anywhere in the OS except that if set, it will prevent sched_releasetcb() from freeing that custom stack.
Add trivial function nxtask_uninit(). This function will undo all operations on a TCB performed by task_init() and release the TCB by calling kmm_free(). This is intended primarily to support error recovery operations after a successful call to task_init() such was when a subsequent call to task_activate fails.
That error recovery is trivial but not obvious. This helper function should eliminate confusion about what to do to recover after calling nxtask_init()
As in https://github.com/apache/incubator-nuttx/issues/1114 discuss, let

-Move task_init() and task_activate() prototypes from include/sched.h to include/nuttx/sched.h. These are internal OS functions and should not be exposed to the user.
-Remove references to task_init() and task_activate() from the User Manual.
-Rename task_init() to nxtask_init() since since it is an OS internal function
-Rename task_activate() to nxtask_activate since it is an OS internal function
The build gets broken when both the NFS and DEBUG_FS_ERROR configurations enabled. This tiny change fixes the compilation error.
Run file through nxstyle and correct issues.

* Apply the recent build script changes introduced in the
following git commits:
- 7e5b0f81e9 and
- e83c1400b6
to this board. Namely, factor the definitions of ARCHINCLUDES
and ARCHXXINCLUDES out of CONFIG_CYGWIN_WINTOOL conditional,
and use new build variable BOARD_DIR to simplify ARCHSCRIPT.
