* Description:
|

* This performs basic initialization of the UART used for the serial
|
||||
* console. Its purpose is to get the console output availabe as soon
|
||||
* as possible.
|
||||
*
|
||||
* The UART0/1/2/3 peripherals are configured using the following registers:
|
||||
* 1. Power: In the PCONP register, set bits PCUART0/1/2/3.
|
||||
* On reset, UART0 and UART 1 are enabled (PCUART0 = 1 and PCUART1 = 1)
|
||||
* and UART2/3 are disabled (PCUART1 = 0 and PCUART3 = 0).
|
||||
* 2. Peripheral clock: In the PCLKSEL0 register, select PCLK_UART0 and
|
||||
* PCLK_UART1; in the PCLKSEL1 register, select PCLK_UART2 and PCLK_UART3.
|
||||
* 3. Baud rate: In the LCR register, set bit DLAB = 1. This enables access
|
||||
* to registers DLL and DLM for setting the baud rate. Also, if needed,
|
||||
* set the fractional baud rate in the fractional divider
|
||||
* 4. UART FIFO: Use bit FIFO enable (bit 0) in FCR register to
|
||||
* enable FIFO.
|
||||
* 5. Pins: Select UART pins through the PINSEL registers and pin modes
|
||||
* through the PINMODE registers. UART receive pins should not have
|
||||
* pull-down resistors enabled.
|
||||
* 6. Interrupts: To enable UART interrupts set bit DLAB = 0 in the LCRF
|
||||
* register. This enables access to IER. Interrupts are enabled
|
||||
* in the NVIC using the appropriate Interrupt Set Enable register.
|
||||
* 7. DMA: UART transmit and receive functions can operate with the
|
||||
* GPDMA controller.

* Button support.
|
||||
*
|
||||
* Description:
|
||||
* up_buttoninit() must be called to initialize button resources. After
|
||||
* that, up_buttons() may be called to collect the current state of all
|
||||
* buttons or up_irqbutton() may be called to register button interrupt
|
||||
* handlers.
|
||||
*
|
||||
* After up_buttoninit() has been called, up_buttons() may be called to
|
||||
* collect the state of all buttons. up_buttons() returns an 8-bit bit set
|
||||
* with each bit associated with a button. See the BUTTON_*_BIT and JOYSTICK_*_BIT
|
||||
* definitions in board.h for the meaning of each bit.
|
||||
*
|
||||
* up_irqbutton() may be called to register an interrupt handler that will
|
||||
* be called when a button is depressed or released. The ID value is a
|
||||
* button enumeration value that uniquely identifies a button resource. See the
|
||||
* BUTTON_* and JOYSTICK_* definitions in board.h for the meaning of enumeration
|
||||
* value. The previous interrupt handler address is returned (so that it may
|
||||
* restored, if so desired).
