Subject: Delete get_plane_numbers() function.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=133c13f5fe676c2db00b05fd990808e9cafac418;p=openbsd

Delete get_plane_numbers() function.

Different from original LUNA(68k), the number of planes is directly
stored as an integer value on LUNA-88K.

Tested on LUNA-88K2 by me.
