xtensa: reorganize vectors placement
Allow vectors to be either merged into the kernel .text or put at a fixed virtual address independently of XIP option. Drop option that puts vectors at a fixed offset from the kernel text. Add choice to Kconfig. Vectors at fixed virtual address may be useful for XIP-aware MTD support and for noMMU configurations with available IRAM. Configurations without VECBASE register must put their vectors at specific locations regardless of the selected option. All other configurations should happily use merged vectors.

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.
