YAMON can expose more than 256MB of RAM to Linux on Malta by passing an ememsize environment variable with the full size, but the kernel then needs to be careful to choose the corresponding physical memory regions, avoiding the IO memory window. This is platform dependent, and on Malta it also depends on the memory layout which varies between system controllers. Extend yamon_dt_amend_memory() to generically handle this by taking [e]memsize bytes of memory from an array of memory regions passed in as a new parameter. Board code provides this array as appropriate depending on its own memory map.

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.
