 * Driver for the on-board character LCD found on some ARM reference boards

 * https://en.wikipedia.org/wiki/HD44780_Character_LCD

 * Currently it will just display the text "ARM Linux" and the linux version

/*

 * __has_attribute is supported on gcc >= 5, clang >= 2.9 and icc >= 17.

 * In the meantime, to support 4.6 <= gcc < 5, we implement __has_attribute

 * In the meantime, to support gcc < 5, we implement __has_attribute

 * by hand.

 *

 * sparse does not support __has_attribute (yet) and defines __GNUC_MINOR__

 * depending on the compiler used to build it; however, these attributes have

 * no semantic effects for sparse, so it does not matter. Also note that,

 * in order to avoid sparse's warnings, even the unsupported ones must be

 * defined to 0.
