+Subject: [PATCH] platform: add Raptor Blackbird support
+
+Based off the Raptor patch:
+https://git.raptorcs.com/git/blackbird-skiboot/commit/?id=c81f9d66592dc2a7cf7f6c59c3def5cee0638c1f
+
+Notable changes are slot names matching what's silkscreened on the board.
+See https://i1.wp.com/www.flamingspork.com/blog/wp-content/uploads/2019/12/IMG_4006-scaled.jpg
+for a photo of the actual board.
+
+I haven't included the port 80h bit as I haven't worked out how to probe that from the BMC to test.
+
+Boot tested, seems good.
