Altera Nios II port submission

[Chung-Lin Tang]

To the GCC Steering Committee,

Mentor Graphics has submitted, and recently re-submitted an updated
version, of a GCC backend port for the Altera Nios II architecture,
currently on gcc-patches awaiting technical review [1].

We're proposing, upon port approval and commit to trunk, Sandra
Loosemore and myself (Chung-Lin Tang), both of Mentor Graphics, as
target maintainers.

Thank you,
Chung-Lin
