This chip exists in two revisions (B2=r3 and B3=r4) on different platforms, and was added without regard to doing proper firmware selection or differentiating between them. Fix this to have proper per-revision firmwares and support Apple NVRAM selection. Revision B2 is present on at least these Apple T2 Macs: kauai: MacBook Pro 15" (Touch/2018-2019) maui: MacBook Pro 13" (Touch/2018-2019) lanai: Mac mini (Late 2018) ekans: iMac Pro 27" (5K, Late 2017) And these non-T2 Macs: nihau: iMac 27" (5K, 2019) Revision B3 is present on at least these Apple T2 Macs: bali: MacBook Pro 16" (2019) trinidad: MacBook Pro 13" (2020, 4 TB3) borneo: MacBook Pro 16" (2019, 5600M) kahana: Mac Pro (2019) kahana: Mac Pro (2019, Rack) hanauma: iMac 27" (5K, 2020) kure: iMac 27" (5K, 2020, 5700/XT) Fixes: 24f0bd136264 ("brcmfmac: add the BRCM 4364 found in MacBook Pro 15,2") Signed-off-by: Hector Martin <marcan@marcan.st> --- .../net/wireless/broadcom/brcm80211/brcmfmac/pcie.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-)
