lpc17_40_userleds.c: Adds the support of Userleds driver which provides a device to manipulate the 4 leds of the board through the /dev/userleds. lpc17_40_leds.c: Removes not used definitions, eg. MBED_LED3_ON. Board LED Status support(CONFIG_ARCH_LED=y) and Device Drivers/Led Support(CONFIG_ARCH_USERLED=y) can not be enable together. Signed-off-by: Gustavo L F Walbon <gwalbon@linux.ibm.com>

* Name: board_app_initialize
|
|
*
|
|
* Description:
|
|
* Perform architecture specific initialization
|
|
*
|
|
* 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 initialization logic and the
|
|
* matching application logic. The value could 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.
