[Markus Rathgeb]

Thanks a lot Anatolij!

I have done the following changes:

============

So, I see now the u-boot on the monitor. More tests will follow.

I changed also CONFIG_SYS_MONITOR_LEN and CONFIG_SYS_MALLOC_LEN.
I do not know, what are the minimum values that are working.
But 128 and 256 for CONFIG_SYS_MALLOC_LEN are to small and with the
above values it is working - so it is okay for me.

Where can I read more about that options (and the options for video)?
Are there documentations or should I read the source code (that is no
problem, but it will be cost a lot of time)?

Thanks again.

Greats,
Markus
