[PATCH] Drop nrv2b support from coreboot

[Uwe Hermann]

Please correct me if I'm wrong, but it looks like noone uses or cares
about nrv2b, we use LZMA since quite a while now, so let's drop nrv2b.

I thought nrv2b was needed for Gigabyte GA-M57SLI-S4 boards with flash
bigger than 512 kB.

Does LZMA do a poor job on those boards?

Those boards are unable to map more than 512 kB of flash at a time. The
contents of bigger flash chips have to be retrieved with programmed I/O
in 3-byte chunks. If the LZMA code assumes the ability to unpack a
mapped image, it will fail. You need the stream decompressor variant of
lzma to get it working. Not sure if that variant is available in the
tree and working.
