tqm8272.c:1086: warning: implicit declaration of function 'writeb'
tqm8272.c: In function 'board_nand_init':
tqm8272.c:1193: error: 'struct nand_chip' has no member named 'write_byte'
make[1]: *** [tqm8272.o] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [board/tqc/tqm8272/libtqm8272.a] Error 2
