Merged in jjlange/nuttx/lpc40xx (pull request #946)
Add support for LPC40xx family chips
* Corrected a few peripheral definitions and pin functions for the LPC17xx family.
Added configuration options, chip definitions, and additional pin functions for the LPC40xx family.
Added board configurations for Embedded Artists LPC4088 Quickstart board and LPC4088 Developer's kit. These configurations are still something of a work in progress. In particular, the LCD functionality is untested.
* First pass rename in *.c and *.h files.
* Renamed LPC17XX to LPC17XX_40XX in config files
* Rplaced LPC17xx with LPC17xx/LPC40xx in .c files
* Replaced LPC17xx with LPC17xx/LPC40xx in .h files
* Updated some documentation
* Working on moving directories
* moved arch/arm/src/lpc17xx and arch/arm/include/lpc17xx to lpc17xx_40xx
* Renamed LPC17_* constants / configuration options to LPC17_40_*
* Updated chip family name defines
* Renamed some chip-specific files
* Updated references to renamed files
* Updated references to lpc17_ to lpc17_40_
* Renamed source files from lpc17_* to lpc17_40_*
* Clean up white space

* Name: board_app_initialize
|

*
|

* Description:
|
||||
* Perform application specific initialization. This function is never
|
||||
* called directly from application code, but only indirectly via the
|
||||
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||
*
|
||||
* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initalization logic and the
|
||||
* matching application logic. The value cold be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

|

* The external functions, lpc17_40_ssp0/1/2select and lpc17_40_ssp0/1/2status
|

* must be provided by board-specific logic. They are implementations of the select
|

|
||||
* include/nuttx/spi/spi.h). All other methods (including lpc17_40_sspbus_initialize())
|
||||
* are provided by common LPC17xx/LPC40xx logic. To use this common SPI logic on your
|
||||
* board:
|
||||
*
|
||||
* 1. Provide logic in lpc17_40_boardinitialize() to configure SPI/SSP chip select
|
||||
* pins.
|
||||
* 2. Provide lpc17_40_ssp0/1/2select() and lpc17_40_ssp0/1/2status() 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 lpc17_40_sspbus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by lpc17_40_sspbus_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).
