There seem to be many whitespace cleanups in this patch. Can you please
post a seperate patch for these for easier review?
I think the baudrate change can be made in unconditionally.
I don't know if you are interested in doing this and I don't mind at
all if you don't, but for a full fixing of these commands I would
suggest the following:
- There should be an internal C API for each load/save function for
noninteractive use.
- Instead of writing to some sdram offset the commands should write
to a file descriptor.
- There should be no more than one positional argument to each command.
A good start would be to cleanup the coding style and to make it compile
again.
I just saw that you copied baudrate switching code from loadb.c. It
tries to get the current baudrate with:
(int)simple_strtoul(dev_get_param(&cdev->class_dev, "baudrate"), NULL, 10);
I wonder if it wouldn't be simpler not to change the baudrate when
no baudrate change is requested.
Another thing: since the loads stuff depends on broken and obviously was
never used since U-Boot it would also be acceptable to remove it
completely and to do a fresh start.
Sascha

I shall send the new patch series in a few minutes.
This patch series will make loads compile again and fix coding style /
compiler's warning.
For simplicity baudrate switching code was removed.
We can add it in the future. Also it isn't very difficult to switch
from direct memory writing to file descriptor writing.
