into a new function that other platforms can share.
This creates a new ofw_reg_to_paddr() function (in a new ofw_subr.c file)
that contains most of the existing ppc implementation, mostly unchanged.
The ppc code now calls the new MI code from the MD code, then creates a
ppc-specific bus_space mapping from the results. The new arm implementation
does the same in an arm-specific way.
This also moves the declaration of OF_decode_addr() from ofw_machdep.h to
openfirm.h, except on sparc64 which uses a different function signature.
This will help all FDT platforms to set up early console access using
OF_decode_addr().
The current code for encoding a netbios name converts each byte to a 16-bit
value and stores the result by casting a char* to u_short*, resulting in
alignment faults on strict-alignment platforms.
This change reimplements the encoding routine using only byte accesses to
memory. There is no particular reason to work with 16-bit values just
because the encoding process creates two bytes of output for every byte of
input. Working a byte at at time also avoids endian problems for big-endian
platforms.

- Do not mark count != 0 case with bsde_get_rule_count as a failure; this

match the physical load address. Remove the *PHYSADDR symbols which are no
longer necessary.
Also remove a bunch of comments, most of which which have been wrong for
quite some time now, and the rest of which are mooted by these changes. All
that's left in this file is assigning a single symbol to its cannonical
value, not much to comment on anymore.
This eliminates the reliance on PHYSADDR and KERNPHYSADDR compile-time
symbols (except when the rom-copy code is enabled) by using the current
PC and the assumption that the entry-point routine is in the first 1MB
section of the text segment.
Other cleanups done:
- Reduce the initarm() stack size back to 2K. It got increased to
4 * 2K when this file was supporting multicore armv6, but that
support is now in locore-v6.S.
- When building the temporary startup page tables, map the entire
4GB address space as VA=PA before mapping the kernel at its loaded
location. This allows access to boot parameters stored somewhere
in ram by the bootloader, regardless of where that may be.
- When building the page table entry for supporting EARLY_PRINTF, map
the section as uncached unbuffered, since it is presumably device
registers.
Note that this restores the ability to use loader(8)/ubldr on armv4/5
kernels. That was broken in r283035, the point at which ubldr started
loading an arm kernel at any 2MB boundary.
Also note that after this, there is no reason to set KERNVIRTADDR to
anything other than 0xc0000000, and no need for PHYSADDR or KERNPHYSADDR
symbols at all.
is what includes machine/ofw_machdep.h. Don't declare OF_decode_addr();
it isn't implemented yet on mips and the declaration for it is about to
be commonized into openfirm.h.
If ExitBootServices fails due to a changed efi_mapkey then GetMemoryMap
must be called again. In this case it is also possible for the memory
map to grow, so repeat the initial GetMemoryMap call to fetch the new
size.
Also roll bi_add_efi_data_and_exit into bi_load_efi_data as there's no
need for it to be a separate function.

Depending on system configuration and parameters, clock_gettime() and
gettimeofday() may not be system calls. If so, passing an invalid pointer
will cause a signal and not an [EFAULT] error.
From a standards perspective, this is OK since passing an invalid pointer is
undefined behaviour.

Instead of using which(1) to look for doxygen, look for it in <LOCALBASE>/bin .
$PATH gets mangled by make buildenv, etc so it's better to just be explicit
about the path if someone uses that for instance.
