Intel OpenBMC Linux kernel source tree (mirror) https://git.radix-linux.su/BMC/Intel-BMC/linux.git/atom?h=dev 2015-05-20T21:10:14+00:00 2015-05-20T21:10:14+00:00 Stefan Agner stefan@agner.ch 2015-05-19T22:03:52+00:00 urn:sha1:8064887e02fd684fa0576cbbcdbc29ceab125c4c 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> 2013-04-02T13:51:27+00:00 Shawn Guo shawn.guo@linaro.org 2013-04-02T13:51:27+00:00 urn:sha1:585b9f0bfdbdb4e41993f52f470eef7f093de0a2 Since we have converted IMX to multiplatform build, Makefile.boot is not used anyway.

In case someone needs to add mx508 support back, then the recommended approach is to use device tree.

DTBs are only built when CONFIG_OF is enabled and now use top level CONFIG_ARCH_xxx instead of chip or board specific config options.
