Applying this patch series and building with gcc version 4.3.3 
(Sourcery G++ Lite 2009q1-203) I get

nand_boot.c: In function 'nand_boot': 

nand_boot.c:356: warning: 'noreturn' function does return 

mkimage.c: In function ?main?: 

mkimage.c:159: warning: implicit declaration of function 
?init_omap_image_type?

same warnings and
