Hello Andrew,

I am sorry for the long delay in reply, I know that it is very difficult to
restore context of the discussion after so long intermission.

Thank you for your comments.
Pertaining to the first, there is a family of SPEAr processors, but they are of
different ARM architectures.
I am familiar with SPEArNet and it has most detailed documentation. The rest of
the processors are not well documented.

As to the common peripheral devices, I could see only MAC110 ethernet
controller is used in other SPEAr MCUs.

I could not come to a definite conclusion in regards to the other peripheral
devices on all SPEAr MCUs.

Neither can I be sure if there is interest in porting eCos on other processors
or boards so far.

Isn't it better to take measures as the demand arises?

As to your other comment, can you point to an example in another processor of
such split code?

Thank you very much in advance.

With best regards,
Vitali Fridliand
