Thanks, I do it.

You are right.

i can say more: this defines are not used anymore and I can drop them. I
have already cleanup the code removing unnecessary defines, but it seems
not enough.

They are obsolete,too. There is already a C struct describing them.
I drop them.

This is a different fall. These defines are used in the assembly
lowlevel_init.S in the first initialization. I cannot remove them.
However, only a part of these defines are currently used and I will drop
the rest of them.
