This PR adds the drivers for Allwinner A64 PIO (Programmable I/O) and PinePhone LEDs (Red / Green / Blue). The PIO Driver is based on the NuttX PIO Driver for Allwinner A10: [`arch/arm/src/a1x/a1x_pio.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_pio.c) - `arch/arm64/src/a64/Make.defs`: Add PIO Driver to Makefile - `boards/Kconfig`: Add `ARCH_HAVE_LEDS` to PinePhone - `boards/arm64/a64/pinephone/src/pinephone.h`: Define PinePhone LEDs - `boards/arm64/a64/pinephone/src/pinephone_boardinit.c`: Start Auto LEDs - `boards/arm64/a64/pinephone/src/pinephone_bringup.c`: Start User LEDs - `boards/arm64/a64/pinephone/src/Makefile`: Add LED Driver to Makefile - `boards/arm64/a64/pinephone/configs/nsh/defconfig`: Add `CONFIG_USERLED` to `nsh` config - `arch/arm64/src/a64/a64_pio.c`, `a64_pio.h`: Allwinner A64 PIO Driver - `arch/arm64/src/a64/hardware/a64_memorymap.h`: PIO Memory Map - `arch/arm64/src/a64/hardware/a64_pio.h`: PIO Definitions - `boards/arm64/a64/pinephone/include/board.h`: Define PinePhone LEDs - `boards/arm64/a64/pinephone/src/pinephone_autoleds.c`: Driver for Auto LEDs - `boards/arm64/a64/pinephone/src/pinephone_userleds.c`: Driver for User LEDs - `introduction/supported_platforms.rst`: Add Allwinner A64 as Supported Platform - `platforms/arm/a64/boards/pinephone/index.rst`: Add PIO and LEDs to PinePhone

* Name: a64_memory_initialize
|
|
*
|
|
* Description:
|
|
* All A64 architectures must provide the following entry point. This
|
|
* entry point is called early in the initialization before memory has
|
|
* been configured. This board-specific function is responsible for
|
|
* configuring any on-board memories.
|
|
*
|
|
* Logic in a64_memory_initialize must be careful to avoid using any
|
|
* global variables because those will be uninitialized at the time this
|
|
* function is called.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:
