Dear Martin,
thank you very very much for being so Kind!
And thank you to all of you for your work!

Your suggestions where precious - and I will look at the referenced device.
In the meantime, I was taking a look at the flash layout. Luckily, it seems EVA will allow me to boot from RAM, which will be very useful.
Still, I am trying to understand as much as possible about this device before making any change.

First of all - I backed up all partitions using nanddump, except for those marked as 2out of reach" in dmesg, which are not readale by nanddump.
I used something like
nanddup -f file /dev/mtd<partition>

Secondly, I was looking at EVA environment, which is as follows:

(wlankey omitted).
I am not able to understand the general syntax for mtd partitions - e.g.: it seems the bootloader uses completely different partition layout).
I don't think I'll need to alter those partitions, but I am better in understanding their definitions should something go wrong in the wrong moment. :)
Thanks again, and sorry for the late answer.
