The file board/Marvell/include/mv_gen_reg.h is incompatible with the GPL (see for example the "MARVELL RESERVES THE RIGHT AT ITS SOLE DISCRETION TO REQUEST THAT THIS CODE BE IMMEDIATELY RETURNED TO MARVELL" clause). As this cannot be fixed, we remove the file and all code that depends on it. Fortunately this only affects some very old boards that have long reached EOL: CPCI750 DB64360 DB64460 p3m750 p3m7448 Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Reinhard Arlt <reinhard.arlt@esd-electronics.com> Cc: Stefan Roese <sr@denx.de> Cc: Roger Meier <r.meier@siemens.com>
