The 2018 13" MacBook Pro (MacBookPro15,2) has a Broadcom chip, the 4364. This chip appears to be specific to Apple and is not found in other hardware. Add this chip to the brcmfmac driver so that it can be recognized automatically. Note that the PCI device id is 4464 even though the chip is referred to as the 4364.

The rambase address was found by trial and error. --- drivers/net/wireless/broadcom/brcm80211/brcmfmac/chip.c | 1 + drivers/net/wireless/broadcom/brcm80211/brcmfmac/pcie.c | 3 +++ drivers/net/wireless/broadcom/brcm80211/include/brcm_hw_ids.h | 2 ++ 3 files changed, 6 insertions(+)
