[U-Boot] [PATCH] EXT4: Fix number base handling of "ext4write" command

[Lukasz Majewski <l.majewski@samsung.com>]

Hi Wolfgang,

> Unlike other commands (for example, "fatwrite"), ext4write would
> interpret the "sizebytes" as decimal number.  This is not only
> inconsistend and unexpected to most users, it also breaks usage
> like this:
> 
> 	tftp ${addr} ${name}
> 	ext4write mmc 0:2 ${addr} ${filename} ${filesize}
> 
> Change this to use the standard notation of base 16 input format.
> See also commit b770e88
> 
> WARNING: this is a change to the user interface!!

In other words you are breaking API :-) - but this change is more than
welcome and you have got enough power to do it :-).

My only comment is to add proper description to the ext4write commend 
description. Now it only says:

"<interface> <dev[:part]> <addr> <absolute filename path> [sizebytes]\n"

and I think, that we could come up with [sizebytes - HEX] or something
similar.
