Hello Daniel,

sorry for being late with my questions.

These patches changing the style, how parameters are given to the kernel
(using cmdline instead of environment).

Can you explain a little, why this is necessary?
Please give some references to the corresponding kernel changes or discussions, if possible.

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
