- Subject: [PATCH] net: bgmac: clarify CONFIG_BCMA dependency
- 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.

- This driver supports GBit MAC and BCM4706 GBit MAC cores on BCMA bus.
- They can be found on BCM47xx SoCs and provide gigabit ethernet.
