drm/nv50: Implement ctxprog/state generation.

This removes dependence on external firmware for NV50 generation cards.
If the generated ctxprogs don't work for you for some reason, please
report it.

+/*
+ * This code deals with PGRAPH contexts on NV50 family cards. Like NV40, it's
+ * the GPU itself that does context-switching, but it needs a special
+ * microcode to do it. And it's the driver's task to supply this microcode,
+ * further known as ctxprog, as well as the initial context values, known
+ * as ctxvals.
+ *
+ * Without ctxprog, you cannot switch contexts. Not even in software, since
+ * the majority of context [xfer strands] isn't accessible directly. You're
+ * stuck with a single channel, and you also suffer all the problems resulting
+ * from missing ctxvals, since you cannot load them.
+ *
+ * Without ctxvals, you're stuck with PGRAPH's default context. It's enough to
+ * run 2d operations, but trying to utilise 3d or CUDA will just lock you up,
+ * since you don't have... some sort of needed setup.
+ *
+ * Nouveau will just disable acceleration if not given ctxprog + ctxvals, since
+ * it's too much hassle to handle no-ctxprog as a special case.
+ */
+
+/*
+ * How ctxprogs work.
+ *
+ * The ctxprog is written in its own kind of microcode, with very small and
+ * crappy set of available commands. You upload it to a small [512 insns]
+ * area of memory on PGRAPH, and it'll be run when PFIFO wants PGRAPH to
+ * switch channel. or when the driver explicitely requests it. Stuff visible
+ * to ctxprog consists of: PGRAPH MMIO registers, PGRAPH context strands,
+ * the per-channel context save area in VRAM [known as ctxvals or grctx],
+ * 4 flags registers, a scratch register, two grctx pointers, plus many
+ * random poorly-understood details.
+ *
+ * When ctxprog runs, it's supposed to check what operations are asked of it,
+ * save old context if requested, optionally reset PGRAPH and switch to the
+ * new channel, and load the new context. Context consists of three major
+ * parts: subset of MMIO registers and two "xfer areas".

+/*
+ * xfer areas. These are a pain.
+ *
+ * There are 2 xfer areas: the first one is big and contains all sorts of
+ * stuff, the second is small and contains some per-TP context.
+ *
+ * Each area is split into 8 "strands". The areas, when saved to grctx,
+ * are made of 8-word blocks. Each block contains a single word from
+ * each strand. The strands are independent of each other, their
+ * addresses are unrelated to each other, and data in them is closely
+ * packed together. The strand layout varies a bit between cards: here
+ * and there, a single word is thrown out in the middle and the whole
+ * strand is offset by a bit from corresponding one on another chipset.
+ * For this reason, addresses of stuff in strands are almost useless.
+ * Knowing sequence of stuff and size of gaps between them is much more
+ * useful, and that's how we build the strands in our generator.
+ *
+ * NVA0 takes this mess to a whole new level by cutting the old strands
+ * into a few dozen pieces [known as genes], rearranging them randomly,
+ * and putting them back together to make new strands. Hopefully these
+ * genes correspond more or less directly to the same PGRAPH subunits
+ * as in 400040 register.
+ *
+ * The most common value in default context is 0, and when the genes
+ * are separated by 0's, gene bounduaries are quite speculative...
+ * some of them can be clearly deduced, others can be guessed, and yet
+ * others won't be resolved without figuring out the real meaning of
+ * given ctxval. For the same reason, ending point of each strand
+ * is unknown. Except for strand 0, which is the longest strand and
+ * its end corresponds to end of the whole xfer.
+ *
+ * An unsolved mystery is the seek instruction: it takes an argument
+ * in bits 8-18, and that argument is clearly the place in strands to
+ * seek to... but the offsets don't seem to correspond to offsets as
+ * seen in grctx. Perhaps there's another, real, not randomly-changing
+ * addressing in strands, and the xfer insn just happens to skip over
+ * the unused bits? NV10-NV30 PIPE comes to mind...
+ *
+ * As far as I know, there's no way to access the xfer areas directly
+ * without the help of ctxprog.
