    V3 of the early platform driver implementation.

    Platform drivers are great for embedded platforms because we can separate
    driver configuration from the actual driver. So base addresses,
    interrupts and other configuration can be kept with the processor or board
    code, and the platform driver can be reused by many different platforms.

    For early devices we have nothing today. For instance, to configure early
    timers and early serial ports we cannot use platform devices. This
    because the setup order during boot. Timers are needed before the
    platform driver core code is available. The same goes for early printk
    support. Early in this case means before initcalls.

    These early drivers today have their configuration either hard coded or
    they receive it using some special configuration method. This is working
    quite well, but if we want to support both regular kernel modules and
    early devices then we need to have two ways of configuring the same
    driver. A single way would be better.

    The early platform driver patch is basically a set of functions that allow
    drivers to register themselves and architecture code to locate them and
    probe. Registration happens through early_param(). The time for the
    probe is decided by the architecture code.

    See Documentation/driver-model/platform.txt for more details.

    Make note of the legacy "probe-the-hardware" drivers, and some APIs that
    are mostly unused except by such drivers. We probably can't escape having
    legacy drivers for a while (e.g. old ISA drivers), but we can at least
    discourage this style code for new drivers, and unless it's unavoidable.

    This is almost a rewrite of the driver-model/platform.txt documentation;
    the previous text was obsolete (for several years), evidently it never
    got updated to match the change from being a PC "legacy_bus" to the more
    widely used core bus for most embedded systems.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
