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.
CONFIG_SYS_MONITOR_LEN could probably be 384 kB or 512 kB. It depends on included (configured) drivers and U-Boot commands. 1024 kB is too big here, i think. 1024 kB for CONFIG_SYS_MALLOC_LEN is OK.
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)?
u-boot/README contains a description of these options. Video related options are described there too. README also describes "videomode" U-Boot environment variable for selection of display resolution and color depth.
