kernel: bgmac: backport patch switching to feature_flags
It was needed upstream to avoid bcma references in the main code. To match this new code our patch adding SRAB was also updated. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

+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.

+Subject: [PATCH 4/5] net: ethernet: bgmac: convert to feature flags
+
+The bgmac driver is using the bcma provides device ID and revision, as
+well as the SoC ID and package, to determine which features are
+necessary to enable, reset, etc in the driver. In anticipation of
+removing the bcma requirement for this driver, these must be changed to
+not reference that struct. In place of that, each "feature" has been
+given a flag, and the flags are enabled for their respective device and
+SoC.
