/* The SAME70Q21 has 2048Kb of FLASH beginning at address 0x0040:0000 and
* 384Kb of SRAM beginining at 0x2040:0000
*
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
* where the code expects to begin execution by jumping to the entry point in
* the 0x0400:0000 address range.
*
* NOTE: that the DTCM address of 0x2000:0000 is used for SRAM. If DTCM is
* disabled, then the accesses will actually occur on the AHB bus.
*
* The user space partition will be spanned with a single region of size
* 2**n bytes. The alignment of the user-space region must be the same.
* As a consequence, as the user-space increases 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 to trim it
* to fit better.
*
* A detailed memory map for the 384KB SRAM region is as follows:
*
* 0x20000 0000: Kernel .data region. Typical size: 0.1KB
* ------- ---- Kernel .bss region. Typical size: 1.8KB
* 0x20000 0800: Kernel IDLE thread stack (approximate). Size is
* determined by CONFIG_IDLETHREAD_STACKSIZE and
* adjustments for alignment. Typical is 1KB.
* ------- ---- Padded to 4KB
* 0x20002 0000: User .data region. Size is variable.
* ------- ---- User .bss region Size is variable.
* 0x20000 2000: Beginning of kernel heap. Size determined by
* CONFIG_MM_KERNEL_HEAPSIZE.
* ------- ---- Beginning of user heap. Can vary with other settings.
* 0x20004 0000: End+1 of mappable internal SRAM

/* LEDs
*
* There are two yellow LED available on the SAM E70 Xplained board that
* can be turned on and off. The LEDs can be activated by driving the
* connected I/O line to GND.
*
* ------ ----------- ---------------------
* SAME70 Function Shared functionality
* PIO
* ------ ----------- ---------------------
* PA23 Yellow LED0 EDBG GPIO
* PC09 Yellow LED1 LCD, and Shield
* ------ ----------- ---------------------
*
* These LEDs are 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/sam_autoleds.c. The LEDs are used to encode
* OS-related events as follows:
*
* ------------------- ----------------------- -------- --------
* SYMBOL Meaning LED state
* LED0 LED1
* ------------------- ----------------------- -------- --------
* LED_STARTED NuttX has been started OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF
* LED_IRQSENABLED Interrupts enabled OFF OFF
* LED_STACKCREATED Idle stack created ON OFF
* LED_INIRQ In an interrupt No change
* LED_SIGNAL In a signal handler No change
* LED_ASSERTION An assertion failed No change
* LED_PANIC The system has crashed N/C Blinking
* LED_IDLE MCU is is sleep mode Not used
* ------------------- ----------------------- -------- --------
*
* Thus if LED0 is statically on, NuttX has successfully booted and is,
* apparently, running normally. If LED1 is flashing at approximately
* 2Hz, then a fatal error has been detected and the system has halted.
*
* NOTE: That LED0 is not used after completion of booting and may
* be used by other board-specific logic.

/****************************************************************************
* 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 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.
* enable - A function pointer that be unsed to enable or disable the
* PHY interrupt.
*
* Returned Value:
* The previous PHY interrupt handler address is returned. This allows you
* to temporarily replace an interrupt handler, then restore the original
* interrupt handler. NULL is returned if there is was not handler in
* place when the call was made.

* This test runs early in initialization before I- and D-caches are

* NOTE: Since the delay loop is calibrate with caches in enabled, the

*
* o sam_spi[0|1]select is a functions tomanage the board-specific chip selects
* o sam_spi[0|1]status and sam_spi[0|1]cmddata: Implementations of the status

* up_spiinitialize()) are provided by common SAM3/4 logic.
*
* To use this common SPI logic on your board:
*
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
* pins.
* 2. Provide sam_spi[0|1]select() and sam_spi[0|1]status() functions in your board-
* specific logic. These functions will perform chip selection and
* status operations using PIOs in the way your board is configured.
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
* sam_spi[0|1]cmddata() functions in your board-specific logic. This
* function will perform cmd/data selection operations using PIOs in
* the way your board is configured.
* 3. Add a call to up_spiinitialize() in your low level application
* initialization logic
* 4. The handle returned by up_spiinitialize() 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).

* Description:

* peripherals. In that case, the pins are completely controlled by the
* SPI driver. This method still needs to be provided, but it may be only
* a stub.
*
* An alternative way to program the PIO chip select pins is as a normal
* PIO output. In that case, the automatic control of the CS pins is
* bypassed and this function must provide control of the chip select.
* NOTE: In this case, the PIO output pin does *not* have to be the
* same as the NPCS pin normal associated with the chip select number.
