They can be found on BCM47xx SoCs and provide gigabit ethernet.
The bgmac driver depends on BCMA_HOST_SOC, which is only used when CONFIG_BCMA is enabled. However, it is a bool option and can be set when CONFIG_BCMA=m, and then bgmac can be built-in, leading to an obvious link error: drivers/built-in.o: In function `bgmac_init': :(.init.text+0x7f2c): undefined reference to `__bcma_driver_register' drivers/built-in.o: In function `bgmac_exit': :(.exit.text+0x110a): undefined reference to `bcma_driver_unregister' To avoid this case, we need to depend on both BCMA and BCMA_SOC, as this patch does. I'm also trying to make the dependency more readable by splitting it into three lines, and adding a COMPILE_TEST alternative so we can test-build it in all configurations that support BCMA. The added dependency on FIXED_PHY addresses a related issue where we cannot call fixed_phy_register() when CONFIG_FIXED_PHY=m and CONFIG_BGMAC=y.
