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")

Hi Hector

Shouldn’t there be a WCC instead of BCA here :

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/wireless/broadcom/brcm80211/brcmfmac/pcie.c?h=v6.2-rc2#n2603

You are right. Thanks for catching that. As Hector is changing that entry he can hopefully take care of it.

Regards,
Arend
