Hi
<sys/cdefs.h> in the nios2 tools is too old to build the current RTEMS.
Newer versions provide __DEVOLATILE
Support is in 4.9.x but it is lacking the RTEMS specifics to allow us to
built it.
Which parts? Didn't we have these for the current configuration? Can't be
very much. :)
The current tools are the Altera versions that have been patched.
Nothing could go upstream and there is only a tarball and no patch.
I am sure they could be extracted and moved over. I do not have the time
to do this and never bothered because nothing was broken until this driver.

Can this code provide the macro is not present as a work around ?
It could but I would rather not. It will end up being a permanent piece
of code
covering up a temporary problem. I see two options:
+ update the nios2 tools
+ provide a small patch to the nios2 tools to define this.
I would prefer the 4.9.x path removing our dependence on the old Altera
tools. Binutils is fine. I have used the latest with old gcc.
