Where is ADP5520_KEYMAPSIZE defined?

I can find a single instance in the tree:

./arch/blackfin/mach-bf537/boards/stamp.c:static const unsigned short adp5520_keymap[ADP5520_KEYMAPSIZE] = {
	
is it runtime-generated or something?

Where is ADP5520_MAXKEYS defined?

It seems odd that keycode is dimensioned with ADP5520_KEYMAPSIZE but
here we iterate up to ADP5520_MAXKEYS.
