/* The i.MXRT1050-EVK has 64Mb of Hyper FLASH beginning at address,
* 0x0060:0000, 512Kb of DTCM RAM beginning at 0x2000:0000, and 512Kb OCRAM
* beginning at 0x2020:0000. Neither DTCM or SDRAM are used in this
* configuration.
*
* The user and kernel space partitions will be spanned with a single
* region of size 2**n bytes. As a consequence, as the partitions increase
* in size, the alignment requirement also increases. The sizes below give
* the largest possible user address spaces (but leave far too much for the
* OS).
*
* The solution to this wasted memory is to (1) use more than one region to
* span the user spaces, or (2) poke holes in a larger region (via sub-
* regions) to trim it to fit better.
*
* A detailed memory map for the 512KB SRAM region is as follows:
*
* 0x2020 0000: Kernel .data region. Typical size: 0.1KB
* ------ ---- Kernel .bss region. Typical size: 1.8KB
* 0x2020 0800: Kernel IDLE thread stack (approximate). Size is
* determined by CONFIG_IDLETHREAD_STACKSIZE and
* adjustments for alignment. Typical is 1KB.
* ------ ---- Padded to 4KB
* 0x2040 0000: User .data region. Size is variable.
* ------- ---- User .bss region Size is variable.
* 0x2042 0000: Beginning of kernel heap. Size determined by
* CONFIG_MM_KERNEL_HEAPSIZE.
* ------ ---- Beginning of user heap. Can vary with other settings.
* 0x2080 0000: End+1 of mappable OCRAM

* or whatever you would like to do with it. Every implementation

/* There are four LED status indicators located on the EVK Board. The
* functions of these LEDs include:
*
* - Main Power Supply(D3)
* Green: DC 5V main supply is normal.
* Red: J2 input voltage is over 5.6V.
* Off: The board is not powered.
* - Reset RED LED(D15)
* - OpenSDA LED(D16)
* - USER LED(D18)
*
* Only a single LED, D18, is under software control.
*
* This LED is not used by the board port unless CONFIG_ARCH_LEDS is
* defined. In that case, the usage by the board port is defined in
* include/board.h and src/imxrt_autoleds.c. The LED is used to encode
* OS-related events as follows:
*
* -------------------- ----------------------- ------
* SYMBOL Meaning LED
* -------------------- ----------------------- ------
*
* LED_STARTED 0 NuttX has been started OFF
* LED_HEAPALLOCATE 0 Heap has been allocated OFF
* LED_IRQSENABLED 0 Interrupts enabled OFF
* LED_STACKCREATED 1 Idle stack created ON
* LED_INIRQ 2 In an interrupt N/C
* LED_SIGNAL 2 In a signal handler N/C
* LED_ASSERTION 2 An assertion failed N/C
* LED_PANIC 3 The system has crashed FLASH
* LED_IDLE Not used
*
* Thus if the LED is statically on, NuttX has successfully booted and is,
* apparently, running normally. If the LED is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.

/****************************************************************************
* Name: arch_phy_irq
*
* Description:
* This function may be called to register an interrupt handler that will
* be called when a PHY interrupt occurs. This function both attaches
* the interrupt handler and enables the interrupt if 'handler' is non-
* NULL. If handler is NULL, then the interrupt is detached and disabled
* instead.
*
* The PHY interrupt is always disabled upon return. The caller must
* call back through the enable function point to control the state of
* the interrupt.
*
* This interrupt may or may not be available on a given platform depending
* on how the network hardware architecture is implemented. In a typical
* case, the PHY interrupt is provided to board-level logic as a GPIO
* interrupt (in which case this is a board-specific interface and really
* should be called board_phy_irq()); In other cases, the PHY interrupt
* may be cause by the chip's MAC logic (in which case arch_phy_irq()) is
* an appropriate name. Other other boards, there may be no PHY interrupts
* available at all. If client attachable PHY interrupts are available
* from the board or from the chip, then CONFIG_ARCH_PHY_INTERRUPT should
* be defined to indicate that fact.
*
* Typical usage:
* a. OS service logic (not application logic*) attaches to the PHY
* PHY interrupt and enables the PHY interrupt.
* b. When the PHY interrupt occurs: (1) the interrupt should be
* disabled and () work should be scheduled on the worker thread (or
* perhaps a dedicated application thread).
* c. That worker thread should use the SIOCGMIIPHY, SIOCGMIIREG,
* and SIOCSMIIREG ioctl calls** to communicate with the PHY,
* determine what network event took place (Link Up/Down?), and
* take the appropriate actions.
* d. It should then interact the PHY to clear any pending
* interrupts, then re-enable the PHY interrupt.
*
* * This is an OS internal interface and should not be used from
* application space. Rather applications should use the SIOCMIISIG
* ioctl to receive a signal when a PHY event occurs.
* ** This interrupt is really of no use if the Ethernet MAC driver
* does not support these ioctl calls.
*
* Input Parameters:
* intf - Identifies the network interface. For example "eth0". Only
* useful on platforms that support multiple Ethernet interfaces
* and, hence, multiple PHYs and PHY interrupts.
* handler - The client interrupt handler to be invoked when the PHY
* asserts an interrupt. Must reside in OS space, but can
* signal tasks in user space. A value of NULL can be passed
* in order to detach and disable the PHY interrupt.
* arg - The argument that will accompany the interrupt
* enable - A function pointer that be unused to enable or disable the
* PHY interrupt.
*
* Returned Value:
* Zero (OK) returned on success; a negated errno value is returned on
* failure.

* They are implementations of the select and status methods of the SPI
* interface defined by struct spi_ops_s (see include/nuttx/spi/spi.h).
* All other methods (including imxrt_lpspibus_initialize()) are provided
* by common STM32 logic. To use this common SPI logic on your board:
*
* 1. Provide logic in imxrt_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide imxrt_lpspi1/2/3select() and imxrt_lpspi1/2/3status()
* functions in your board-specific logic.
* These functions will perform chip selection and status operations
* using GPIOs in the way your board is configured.
* 3. Add a calls to imxrt_lpspibus_initialize() in your low level
* application initialization logic
* 4. The handle returned by imxrt_lpspibus_initialize() may then be used
* to bind the SPI driver to higher level logic (e.g., calling
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
* the SPI MMC/SD driver).
