[U-Boot] cmd_sf warning on size_t

Hi Mike,

I got this warning on cmd_sf.c,

cmd_sf.c: In function `spi_flash_update_block':
cmd_sf.c:130: warning: unsigned int format, size_t arg (arg 4)
cmd_sf.c:135: warning: unsigned int format, size_t arg (arg 3)


It was related to our arch/avr32|blackfin|nios2/asm/posix_types.h
typedef unsigned long __kernel_size_t;

While most other 32 bits archs use unsigned int, we three use unsigned long.

It is said in linux-2.6/include/asm-generic/posix_types.h
/*
  * Most 32 bit architectures use "unsigned int" size_t,
  * and all 64 bit architectures use "unsigned long" size_t.
  */

Shall we fix the cmd_sf.c, or shall I change size_t to unsigned int as 
other 32 bits archs do?

Best regards,
Thomas
