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. + +Signed-off-by: Arnd Bergmann <arnd@arndb.de> +Signed-off-by: David S.
