[PATCH_V2 31/34] MIPS: add jz4780 Ingenic vendor ID

From: Zubair Lutfullah Kakakhel
Date: Wed Feb 04 2015 - 10:26:44 EST


From: Paul Burton <paul.burton@xxxxxxxxxx>

With the jz4780, Ingenic switched to use a different vendor ID in the
coprocessor 0 PRID register (whilst keeping the product ID & revision
the same as the jz4740 & jz4770...). Add a definition for the new
vendor ID & handle it in the same way as the older one.
