Hello Daniel,
sorry for being late with my questions.

'rd_start' and 'rd_size'
These patches changing the style, how parameters are given to the kernel (using cmdline instead of environment)
The environment is still available
Can you explain a little, why this is necessary? Please give some references to the corresponding kernel changes or
discussions, if possible.
the current U-Boot kernel interface emulates the YAMON interface. But almost all boards supported by the kernel are bootloader agnostic or don't use U-Boot.
And how about backward compatibility? Will it still be possible to boot
older kernels?
When you automatically add the variable 'mem', will it still be possible to override the memory size by manually adding it to the bootargs?
Best Regards, Thomas
