Description

I have attached a patch for rtems-4.6.4. It adds a leon3 bsp, and also removes the need for non-fpu bsps (erc32nfp, leon2nfp). The sparc code now automatically detects fpu presence at run-time, rather than at compile-time. The patch also includes a network driver for the Opencores ethernet MAC.

It includes the previously described changes, and also a lan91c111 ethernet driver. The driver has attach functions in leon2 and leon3 bsps, but sits in libchip so it is available for general use.

Release:
unknown
