stm32_i2sdev_initialize to stm32_i2sbus_initiliaze, to be consistent
with the way other buses are initialized.
The stm32_i2sdev_initiliaze (similar to stm32_spidev_initialize for
example) is a board specific function that does any necessary
initialization that's board depedent.
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.
boards/arm/stm32/b-g474e-dpow1/scripts/Make.defs:
* 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.
Add support for the STM32G474 family of microcontrollers and the
B-G474E-DPOW1 Discovery Board, which features a STM32G474RET6.
This is a major pull request as it adds support for an entirely
new family of STM32. This support is implemented in
arch/arm/src/stm32 and shares implementation with other STM32
families supported by that code, such as the 'L15xx, 'F10xx,
'F20xx, 'F3xxx, and 'F4xxx.
boards/Kconfig:
* Make NuttX recognize the existence of b-g474e-dpow1,
the B-G474E-DPOW1 Discovery Board.

Board. The board boots successfully through to the
NSH prompt. NSH runs and is responsive.
