+Sparc32 keyboard
+----------------
+SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
+of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
+and uses that value to select keyboard layout. Also the SUN bios like the one
+in the file ss5.bin uses this value to support at least some keyboard layouts.
+However, the OpenBIOS provided with qemu is hardcoded to always use an
+US keyboard layout.
+
+With the escc.chnA-sunkbd-layout driver property it is possible to select
+keyboard layout. Example:
+
+-global escc.chnA-sunkbd-layout=de
+
+Depending on type of keyboard, the keyboard can have 6 or 5 dip-switches to
+select keyboard layout, giving up to 64 different layouts. Not all
+combinations are supported by Solaris and even less by Sun OpenBoot BIOS.
+
+The dip switch settings can be given as hexadecimal number, decimal number
+or in some cases as a language string. Examples:
+
+-global escc.chnA-sunkbd-layout=0x2b
+
+-global escc.chnA-sunkbd-layout=43
+
+-global escc.chnA-sunkbd-layout=sv
+
+The above 3 examples all select a swedish keyboard layout. Table 3-15 at
+https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html explains which
+keytable file is used for different dip switch settings. The information
+in that table can be summarized in this table:

+Not all dip switch values have a corresponding language code and both "be" and
+"nl-be" correspond to the same dip switch value. By default, if no value is
+given to escc.chnA-sunkbd-layout 0x21 (en-us) will be used.
