ARM: vf610: enable Cortex-M4 configuration on Vybrid SoC This patch allows to build the Kernel for Vybrid (VF6xx) SoC when ARMv7-M CPU is selected. The resulting image runs on the secondary Cortex-M4 core. This core has equally access to all peripherals as the main Cortex-A5 core. However, there is no resource control mechanism, hence when both cores are used simultaneously, orthogonal device tree's are required. The boot CPU is dependent on the SoC variant. The available boards use mostly variants where the Cortex-A5 is the primary and hence the boot CPU. Booting the secondary Cortex-M4 CPU needs SoC specific registers written. There is no in kernel support for this right now, a external userspace utility called "m4boot" can be used to boot the kernel: m4boot xipImage initramfs.cpio.lzo vf610m4-colibri.dtb Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Arnd Bergmann <arnd@arndb.de> 2015-05-20 01:03:52 +03:00			`"fsl,vf610m4",`

ARM: l2c: imx vf610: convert to generic l2c OF initialisation Remove the explicit call to l2x0_of_init(), converting to the generic infrastructure instead. Since the .init_irq method only calls irqchip_init(), we can remove that too as the generic code will take care of that.
