Board Specific Compilation Flags

Board specific compilation flags must be specified in the file:
	config/<cpu>-<board>/make.defs
   
In general, it is recommended to specify additional flags and avoid overriding completely existing flags. In other words, the recommended way is to use += in macro definition. For example:

	CFLAGS+=-fomit-frame-pointer
   

The board specific compilation flags must declare at least the following make variables:

CPU This is the name of the CPU architecture. Choose either m68hc11 or m68hc12.
BOARD This is the board name extension. The name is important and is used to construct the compiler include directive to access to the board specific includes.
