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.
