[ixp1200] MicroEngine C -> segment access?

[Heaton, Eric D]

Mirko,

Crossing the 1k boundary for IXP12XX with 2k control store should be
transparent for the programmer.  Just remember to set the following switches
correctly:

-Qrevision_min=n
-Qrevision_max=m
The version arguments allow the compiler to generate code that will
work on a range of processor versions.
1=B0; 3=C0; 5=D0.
Use 3 to enable C0 support (2K microcode) in the compiler. Use 5 for
the IXP1240 and the IXP1250. Use min and max to set the range of
processor versions that the code will run on.
Note: The loader will error if you try to load on an incorrect processor
version.

Hello,

How to access the second micro store segment of 
the C step IXP1200 from C?

Thanks,
Mirko
