Use OF_getencprop over OF_getprop and fdt32_to_cpu. The latter may give
us the wrong data in the failure case if shift was not zero.
Remove the extra copy of uart_fdt_get_clock and uart_fdt_get_shift. While
here also use OF_getencprop in uart_fdt_get_clock.
Move uart_fdt_get_clock and uart_fdt_get_shift to uart_bus_fdt.c, we may
not build uart_cpu_fdt.c in all configs.
Fix uart_fdt_get_clock. It should have been using the cell variable passed
in, not value on the stack.

Define new linker set, UART_FDT_CLASS_AND_DEVICE, for registering full
(class and device) FDT UART. Define second one, UART_FDT_CLASS, for UART
class only.
Move the uart_class definitions and fdt compat data into the individual
uart implementations, and export them using the new linker-set mechanism.

Add Atmel serial drivers.
uart clock-frequency is a FreeBSD-specific extention. Make it optional and
allow the client uart drivers to decide if a frequency is required.
Remove redundant declaration for uart devclass.
Commit some unrelated, but harmless, FDT ifdefs.
Add at91 NAND support, Fix comment.
Remove obsolete options and fix comments

Add some extra sanity checking and checks to printf format specifiers.
Try even harder to find a console before giving up.
Make devices with registers into the KVA region work reliably.
Turn on VM_KMEM_SIZE_SCALE on 32-bit as well as 64-bit PowerPC.
Return NOKEY instead of 0 if there are no more key presses queued.

Test UARTs physical address instead of virtual.
Be a bit more flexible in how we find the console from the properties on
/chosen, following the list of allowed console properties in ePAPR. Also
do not require that stdin be defined and equal to stdout: stdin is
nonstandard (for ePAPR) and console in an unexpected place is after all
better than no console.

Arrange for uart_cpu_fdt's probe() routine to use the same table of compat
strings as uart_bus_fdt's probe().

The TI uart hardware is ns16550-compatible, except that before it can
be used the clocks and power have to be enabled and a non-standard
mode control register has to be set to put the device in uart mode
(as opposed to irDa or other serial protocols). This adds the extra
code in an extension to the standard ns8250 probe routine, and the
rest of the driver is just the standard ns8250 code.

device compatible with multiple drivers matches the more specific driver
first and doesn't overwrite it later with the more generic. Move the
generic ns16550 to the end of the list.

1. Common headers for fdt.h and ofw_machdep.h under x86/include
with indirections under i386/include and amd64/include.
2. New modinfo for loader provided FDT blob.
3. Common x86_init_fdt() called from hammer_time() on amd64 and
init386() on i386.
4. Split-off FDT specific low-level console functions from FDT
bus methods for the uart(4) driver. The low-level console
logic has been moved to uart_cpu_fdt.c and is used for arm,
mips & powerpc only. The FDT bus methods are shared across
all architectures.
5. Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
fdt_pic_table[] arrays. Both are empty right now.
FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.
