Here are some patches needed for newer chipsets that do things just
a bit differently. Should not affect currently supported devices.
This series applies to the master branch of the wireless-drivers-next
repository.
Arend van Spriel (4):
brcmfmac: use different error value for invalid ram base address
brcmfmac: increase core revision column aligning core list
brcmfmac: add xtlv support to firmware interface layer
brcmfmac: support chipsets with different core enumeration space

2.27.0
The function brcmf_chip_tcm_rambase() returns 0 as invalid ram base
address. However, upcoming chips have ram base address starting at
zero so we have to find a more appropriate invalid value to return.

Some cores are getting a revision greater that 99 thus messing up
the column alignment in the list of cores. So adding a digit for
the core revision.

Newer firmware API require commands to use xtlv format. Add support
for that in the firmware interface layer.

Historically the broadcom wifi chipsets always had enumeration
space containing all core information at same place. However, for
new chipsets the ASIC developers moved away from that given fact.
So we have to accommodate that it can differ per chipset.
