I wonder how it works. At the mapin_ram(), my BAT are overwritten,

No they're not. the BAT configurations (which will be used later by
load_up_mmu) are written, NOT the BATs themselves.

Ok, thanks. That's what I've missed.

then the "MMU:setio" progress is called, but at this point, my BAT
is no longer active and my setup_io_mappings is not yet
called. Shouldn't that crash ? During these two calls, the uart zone
shouldn't be mapped.

setup_io_mappings is similar to mapin_ram. the configurations are
changed but not the BATs.
