Before this patch csky-linux need CONFIG_RAM_BASE to determine start physical address. Now we use phys_offset variable to replace the macro of PHYS_OFFSET and we setup phys_offset with real physical address which is determined during startup in head.S. With this patch we needn't re-compile kernel for different start physical address. ie: 0x0 / 0xc0000000 start physical address could use the same vmlinux, be care different start address must be 512MB aligned.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
