That's what I expected. Please do add proper protection, so that
everybody who copies the code for a real production board has a sane
implementation.

If you are worried about having to type too many commands for update,
please consider pre-defining useful macros like we do in so many other
boards; for example:

"include/configs/aria.h":

	"u-boot=aria/u-boot.bin\0"
	...
	"load=tftp ${u-boot_addr_r} ${u-boot}\0"
	...
	"update=protect off ${u-boot_addr} +${filesize};"               \
		"era ${u-boot_addr} +${filesize};"                      \
		"cp.b ${u-boot_addr_r} ${u-boot_addr} ${filesize}\0"

so you only have to type "run load update".

Best regards,

Wolfgang Denk
