Add a uart attachment/syscons keyboard driver for sun keyboards. In theory this will work with any uart backend, currently supported hardware uses either ns8250 or z8530. 2003-11-11 07:33:24 +00:00			`* Copyright (c) 2002 Jason L. Wright (jason@thought.net)`

- In sunkbd_probe_keyboard() don't bother to determine the keyboard layout as we have no use for that info. Instead let this function return the keyboard ID and verify at its invocation in sunkbd_configure() that we're talking to a Sun type 4/5/6 keyboard, i.e. a keyboard supported by this driver. - Add an option SUNKBD_EMULATE_ATKBD whose code is based on the respective code in ukbd(4) and like UKBD_EMULATE_ATSCANCODE causes this driver to emit AT keyboard/KB_101 compatible scan codes in K_RAW mode as assumed by kbdmux(4). Unlike UKBD_EMULATE_ATSCANCODE, SUNKBD_EMULATE_ATKBD also triggers the use of AT keyboard maps and thus allows to use the map files in share/syscons/keymaps with this driver at the cost of an additional translation (in ukbd(4) this just is the way of operation). - Implement an option SUNKBD_DFLT_KEYMAP, which like the equivalent options of the other keyboard drivers allows to specify the default in-kernel keyboard map. For obvious reasons this made to only work when also using SUNKBD_EMULATE_ATKBD. - Implement sunkbd_check(), sunkbd_check_char() and sunkbd_clear_state(), which are also required for interoperability with kbdmux(4). - Implement K_CODE mode and FreeBSD keypad compose. - As a minor hack define KBD_DFLT_KEYMAP also in the !SUNKBD_EMULATE_ATKBD case so we can obtain fkey_tab from <dev/kbd/kbdtables.h> rather than having to duplicate it and #ifdef some more code. - Don't use the TX-buffer for writing the two command bytes for setting the keyboard LEDs as this consequently requires a hardware FIFO that is at least two bytes in depth, which the NMOS-variant of the Zilog SCCs doesn't have. Thus use an inlined version of uart_putc() to consecutively write the command bytes (a cleaner approach would be to do this via the soft interrupt handler but that variant wouldn't work while in ddb(4)).
