This bool kconfig symbol:

config BRCMFMAC_SDIO
bool "SDIO bus interface support for FullMAC driver"
depends on MMC

allows BRCMFMAC_SDIO to be y even when MMC=m.

Is there a reasonable solution to this?

Actually, BRCMFMAC should be built in same form as the MMC and/or USB,
but only when BRCMFMAC_SDIO or BRCMFMAC_USB are selected.

So valid combinations are:
MMC=m, USB=m, BRCMFMAC_SDIO=y, BRCMFMAC_USB=y => BRCMFMAC=m
MMC=m, USB=y, BRCMFMAC_SDIO=y, BRCMFMAC_USB=y => BRCMFMAC=m
MMC=y, USB=m, BRCMFMAC_SDIO=y, BRCMFMAC_USB=y => BRCMFMAC=m
MMC=m, USB=y, BRCMFMAC_SDIO=y, BRCMFMAC_USB=n => BRCMFMAC=m
MMC=m, USB=y, BRCMFMAC_SDIO=n, BRCMFMAC_USB=y => BRCMFMAC=m|y
MMC=y, USB=m, BRCMFMAC_SDIO=y, BRCMFMAC_USB=n => BRCMFMAC=m|y
MMC=y, USB=m, BRCMFMAC_SDIO=n, BRCMFMAC_USB=y => BRCMFMAC=m
MMC=y, USB=y, BRCMFMAC_SDIO=y, BRCMFMAC_USB=y => BRCMFMAC=m|y
MMC=y, USB=y, BRCMFMAC_SDIO=y, BRCMFMAC_USB=n => BRCMFMAC=m|y
MMC=y, USB=y, BRCMFMAC_SDIO=n, BRCMFMAC_USB=y => BRCMFMAC=m|y

Not sure how to express the above.

This should be expressed with this Kconfig:

config BRCMFMAC_USB
bool "USB bus interface support for FullMAC driver"
depends on (USB = y || USB = BRCMFMAC)
depends on BRCMFMAC

config BRCMFMAC_SDIO
bool "SDIO bus interface support for FullMAC driver"
depends on (MMC = y || MMC = BRCMFMAC)
depends on BRCMFMAC
select FW_LOADER

I haven't tested it, but we had a similar problem in b43 and fixed it
like this.

Thanks, Hauke

I will create a patch fixing this.

Arend
