* Name: board_autoled_initialize
81+
*
82+
* Description:
83+
* This function is called very early in initialization to perform board-
84+
* specific initialization of LED-related resources. This includes such
85+
* things as, for example, configure GPIO pins to drive the LEDs and also
86+
* putting the LEDs in their correct initial state.
87+
*
88+
* NOTE: In most architectures, board_autoled_initialize() is called from
89+
* board-specific initialization logic. But there are a few architectures
90+
* where this initialization function is still called from common chip
91+
* architecture logic. This interface is not, however, a common board
92+
* interface in any event and, hence, the usage of the name
93+
* board_autoled_initialize is deprecated.
94+
*
95+
* WARNING: This interface name will eventually be removed; do not use it
96+
* in new board ports. New implementations should use the naming
97+
* conventions for "Microprocessor-Specific Interfaces" or the "Board-
98+
* Specific Interfaces" as described above.
99+
*

* Input Parameters:
101+
* None
