I need help on this. I had a similar problem for cmd_sf in 20111214.

This patch works for gcc-4.7.3, but triggers warning for gcc-3.4.6 and 
gcc-4.1.2.


Before,

gcc-3.4.6 and gcc-4.1.2 got no warning.

gcc-4.7.2 got

spi_flash.c: In function 'spi_flash_read_write':
spi_flash.c:42:3: warning: format '%zu' expects argument of type 
'size_t', but argument 2 has type 'long unsigned int' [-Wformat]

After this patch,

gcc-4.7.2 got no warning,

gcc-3.4.6 and gcc-4.1.2 got warning,
