The BAR2 also has an offset (RAM start, presumably), so add that. Signed-off-by: Hector Martin Reviewed-by: Sven Peter [sven: rebased, updated some comments, mentioned 4388 in Kconfig] Signed-off-by: Sven Peter Reviewed-by: Neal Gompa --- Hi, This is just a single commit mostly written by Hector that adds support for BCM4388 chips. I've just rebased this to the current bluetooth-next since it also needs 9dc8ac15ca5 and adjusted some comments.
