This variable is used for our default bootcmd to define the kernel size which needs to be copied
from the address pointed by the 'kernel_start' variable to the address pointed to by
the 'kernel_load' variable:

#define CONFIG_BOOTCOMMAND		"cp.b $kernel_start $kernel_load "     \
					"$kernel_size && bootm $kernel_load"
