o Now CONFIG_PHYSICAL_START is being replaced with CONFIG_PHYSICAL_ALIGN. Hardcoding the kernel physical start value creates a problem in relocatable kernel context due to boot loader limitations. For ex, if somebody compiles a relocatable kernel to be run from address 4MB, but this kernel will run from location 1MB as grub loads the kernel at physical address 1MB. Kernel thinks that I am a relocatable kernel and I should run from the address I have been loaded at. So somebody wanting to run kernel from 4MB alignment location (for improved performance regions) can't do that. o Hence, Eric proposed that probably CONFIG_PHYSICAL_ALIGN will make more sense in relocatable kernel context. At run time kernel will move itself to a physical addr location which meets user specified alignment restrictions.
