The XIP linker script has several problems: - PAGE_ALIGNED_DATA is missing and is likely to end up somewhere with the wrong LMA. - BUG_TABLE definitely has the wrong LMA, it is not copied to RAM, and its VMA is unaccounted for and likely to clash with dynamic memory usage. - TCM usage is similarly broken. - PERCPU_SECTION is left in ROM despite being written to. Let's use generic macros for those things and locate them appropriately. Incidentally, those macros are usable with a LMA != VMA already by properly defining LOAD_OFFSET. TCM is not fixed here. It never worked in a XIP configuration anyway, so that can wait until another round of cleanups.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
