I agree that this makes it even worse to be enabled as built-in. I will try to change the way of work for NXP developers. If they really need these drivers to be built-in they will need to maintain a config fragment in private to do that. > > Since all the options that this commit enables are tristate, let's > switch them all to =m > > Fixes: 97c1ed02f765bc89 ("arm64: defconfig: Enable PHY devices used on > QorIQ boards") > Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Acked-by: Li Yang <leoyang.li@nxp.com> > --- > arch/arm64/configs/defconfig | 10 +++++----- > 1 file changed, 5 insertions(+), 5 deletions(-) > > diff --git a/arch/arm64/configs/defconfig b/arch/arm64/configs/defconfig > index 883e8bace3ed..b0c5cf72a4c3 100644 > --- a/arch/arm64/configs/defconfig > +++ b/arch/arm64/configs/defconfig > @@ -318,17 +318,17 @@ CONFIG_STMMAC_ETH=m > CONFIG_TI_K3_AM65_CPSW_NUSS=y > CONFIG_QCOM_IPA=m > CONFIG_MDIO_BUS_MUX_MMIOREG=y > -CONFIG_MDIO_BUS_MUX_MULTIPLEXER=y > -CONFIG_AQUANTIA_PHY=y > +CONFIG_MDIO_BUS_MUX_MULTIPLEXER=m > +CONFIG_AQUANTIA_PHY=m > CONFIG_MARVELL_PHY=m > CONFIG_MARVELL_10G_PHY=m > CONFIG_MESON_GXL_PHY=m > CONFIG_MICREL_PHY=y > -CONFIG_MICROSEMI_PHY=y > +CONFIG_MICROSEMI_PHY=m > CONFIG_AT803X_PHY=y > CONFIG_REALTEK_PHY=m > CONFIG_ROCKCHIP_PHY=y > -CONFIG_VITESSE_PHY=y > +CONFIG_VITESSE_PHY=m > CONFIG_USB_PEGASUS=m > CONFIG_USB_RTL8150=m > CONFIG_USB_RTL8152=m > @@ -951,7 +951,7 @@ CONFIG_OPTEE=y > CONFIG_SLIMBUS=m > CONFIG_SLIM_QCOM_CTRL=m > CONFIG_SLIM_QCOM_NGD_CTRL=m > -CONFIG_MUX_MMIO=y > +CONFIG_MUX_MMIO=m > CONFIG_EXT2_FS=y > CONFIG_EXT3_FS=y > CONFIG_EXT4_FS_POSIX_ACL=y > -- > 2.27.0

The arm64 port adopts a single image policy, and therefore has a single defconfig that should produce a kernel that can boot on any platform. Given the shared nature, we typically enable tristate Kconfig options as modules, unless there is a good reason to enable it as a builtin. In the case of commit 97c1ed02f765bc89 ("arm64: defconfig: Enable PHY devices used on QorIQ boards"), this is not really the case, and the various options are enabled as builtins as a convenience for the NXP developers that actually work on such boards. This pulls in other dependencies, such as CRYPTO_AES and CRYPTO_ECB (for MICROSEMI_PHY), which themselves pull in other pieces of the crypto stack. Since all the options that this commit enables are tristate, let's switch them all to =m Fixes: 97c1ed02f765bc89 ("arm64: defconfig: Enable PHY devices used on QorIQ boards") Signed-off-by: Ard Biesheuvel <ardb@kernel.org> --- arch/arm64/configs/defconfig | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-)
