freebsd kernel with SKQ

- Move prototypes for sparc64-specific helper functions from bus.h to bus_private.h - Move the method pointers from struct bus_dma_tag into a separate structure; this saves some memory, and allows to use a single method table for each busdma backend, so that the bus drivers need no longer be changed if the methods tables need to be modified. - Remove the hierarchical tag method lookup. It was never really useful, since the layering is fixed, and the current implementations do not need to call into parent implementations anyway. Each tag inherits its method table pointer and cookie from the parent (or the root tag) now, and the method wrapper macros directly use the method table of the tag. - Add a method table to the non-IOMMU backend, remove unnecessary prototypes, remove the extra parent tag argument. - Rename sparc64_dmamem_alloc_map() and sparc64_dmamem_free_map() to sparc64_dma_alloc_map() and sparc64_dma_free_map(), move them to a better place and use them for all map allocations and deallocations. - Add a method table to the iommu backend, and staticize functions, remove the extra parent tag argument. - Change the psycho and sbus drivers to just set cookie and method table in the root tag. - Miscellaneous small fixes. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
