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’

Using gcc version 4.5.1 (Sourcery G++ Lite 2010.09-50) results in the 
same warnings and
