kernel: Move to Linux v4.14.1-openpower1 Integrate v4.14.1 stable release Update P9 kernel defconfig with 4.14 related options: Harden slab freelist metadata (SLAB_FREELIST_HARDENED)=y IBM Virtual Accelerator Switchboard (VAS) (PPC_VAS)=n Network Service Header (NSH) protocol (NET_NSH)=n Mellanox Technologies MLX5 MPFS support (MLX5_MPFS)=n Mellanox Technologies MLX5 SRIOV E-Switch support (MLX5_ESWITCH)=n RmNet MAP driver (RMNET)=n Large payload keys (BIG_KEYS)=n We build in the MLX5 driver but the help text suggests we do not need those features compiled in for petitboot. We do not use the VAS features in petitboot. I40E is required by Boston and P8 SMC machines, so it is retained in the configuration. IGB is dropped as it was not enabled when moving to 4.14 and no one noticed. The P8 kernel defconfig is updated to be in line with the P9 defconfig. The only difference at this stage is the default commandline which contains workarounds for P9: -CONFIG_CMDLINE="console=tty0 console=hvc0 powersave=off" +CONFIG_CMDLINE="console=tty0 console=hvc0 quiet" Signed-off-by: Joel Stanley <joel@jms.id.au>
The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

To build an image for a Palmetto system:
git clone --recursive git@github.com:open-power/op-build.git cd op-build . op-build-env op-build palmetto_defconfig && op-build
There are also default configurations for other platforms in openpower/configs/ such as Habanero and Firestone.
Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.
