  • At present stdio device functions do not get any clue as to which stdio
    device is being acted on. Some implementations go to great lengths to work
    around this, such as defining a whole separate set of functions for each
    possible device.

    For driver model we need to associate a stdio_dev with a device. It doesn't
    seem possible to continue with this work-around approach.

    Instead, add a stdio_dev pointer to each of the stdio member functions.

    Note: The serial drivers have the same problem, but it is not strictly
    necessary to fix that to get driver model running. Also, if we convert
    serial over to driver model the problem will go away.

    Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

  • The BIOS leaves the keyboard enabled during boot time so that any
    keystroke would interfere kernel driver initialization.

    Add a way to disable the keyboard to make sure no scancode will be
    generated during the boot time. Note that the keyboard will be
    re-enabled again after the kernel driver is up.

    This code can be called from the board functions.

  • On x86, the i8042 keyboard controller driver frequently waits for the keyboard
    input buffer to be empty to make sure the controller has had a chance to
    process the data it was given. The way the delay loop was structured, if the
    controller hadn't cleared the corresponding status bit immediately, it would
    wait 1ms before checking again. If the keyboard responded quickly but not
    instantly, the driver would still wait a full 1ms when perhaps 1us would have
    been sufficient. Because udelay is a busy wait anyway, this change decreases
    the delay between checks to 1us.

    Also, this change gets rid of a hardcoded 250ms delay.

    On Stumpy, this saves 100-150ms during boot.
