CONFIG_DYNAMIC_MEMSTART: Enable page aligned dynamic load address for kernel

General informations

The Linux kernel configuration item CONFIG_DYNAMIC_MEMSTART has multiple definitions:

Enable page aligned dynamic load address for kernel (EXPERIMENTAL) found in arch/powerpc/Kconfig

The configuration item CONFIG_DYNAMIC_MEMSTART:

Help text

This option enables the kernel to be loaded at any page aligned physical address. The kernel creates a mapping from KERNELBASE to the address where the kernel is loaded. The page size here implies the TLB page size of the mapping for kernel on the particular platform. Please refer to the init code for finding the TLB page size.

DYNAMIC_MEMSTART is an easy way of implementing pseudo-RELOCATABLE kernel image, where the only restriction is the page aligned kernel load address. When this option is enabled, the compile time physical address PHYSICAL_START is ignored.

This option is overridden by RELOCATABLE
