The kernel receives the parameters describing the -layout over the kernel command line. These parameters are automatically -generated by Barebox. You can change these parameters in Barebox menuconfig. The -RAMOOPS parameters for the Kernel are stored in the variable -global.linux.bootargs.ramoops. +layout via devicetree or - as a fallback - over the kernel command line. +To ensure both worlds are using the same memory layout, the required +configuration data for the kernel is generated on-the-fly prior booting a kernel. +For the devicetree use case Barebox adapts the kernel's devicetree, for the +kernel command line fallback the variable ``global.linux.bootargs.ramoops`` is +created and its content used to build the kernel command line. You can adapt the *pstore* parameters in Barebox menuconfig. |
