Rework ofmem_malloc() so that it takes a parameter specifying the alignment for the allocation and then change the API
to match that of posix_memalign(). Then create ofmem_malloc() as a simple wrapper function onto ofmem_posix_memalign()
using a default alignment of CONFIG_OFMEM_MALLOC_ALIGN.

A casual glance at the source code suggests that pointers returned by ofmem_malloc() are aligned, but in fact they are not
because sizeof(alloc_desc_t) is added to the final pointer return value. Create some additional padding after the previous value
of ofmem->next_malloc so we can store the alloc_desc_t underneath the final return pointer in memory, thus ensuring that the
final pointer is aligned correctly.

On sparc64 a virtual address or size value is contained within one stack cell
but that makes two property cells. The columns for the /virtual-memory
"available" property thus looked wrong.
Do read the number of cells from #address-cells but make sure the size is
at least one to not break ppc.

Based on Mark's previous work, let ofmem handle addresses wider than one cell.
This is based on the assumption that sizeof(phys_addr_t) >= sizeof(ucell).
Affected are in particular sparc32 (36 bits) and ppc64 (64 bits).
As a consequence, some range_t related code shared with virtual/effective
addresses needed to be migrated, too. Since both address types are unsigned
this should be okay.
v4:
* Coding style fixes and comments, as suggested by Mark.
v3:
* Rebased: Prefer FMT_plx for trace output.
* Convert some more places to phys_addr_t to avoid breakage on ppc64.
* Add helpers ofmem_arch_{get_physaddr_cellsize,encode_physaddr}(),
requested by Mark.
v2:
* Use FMT_physaddr_t in ofmem trace code. (by Mark)

Depending on the condition, either the [IFDEF] FOO or the [ELSE]
would get compiled as an [IF], eating words until [ELSE] or [THEN]
respectively. While doing so, [IFDEF] does not get compiled to [IF],
so we need to handle nested [IFDEF] to account for its [ELSE] or [THEN].
This fixes [IFDEF] not disabling the full section of code.

To store a full 64-bit address we need two cells. This setting matches
Apple's OpenFirmware on my G5 and IBM's firmware on the JS20.
The PCI driver zero-pads its physical addresses, so is okay as long as devices
remain in lower 32 bits. ofmem needs changes for memory ranges and translations.
Note that an enlarged #size-cells is not strictly needed
and constitutes a difference between Apple and IBM firmware (1 vs. 2).
v2:
* Introduce local helper push_physaddr(). A more general, global definition
was not easily reachable due to inability to determine in preprocessor
whether phys_addr_t is wider than ucell, leading to compilation errors
due to a shift the size of the variable.

In the ppc64 ELF ABI, similar to ia64, a function's symbol does not directly

Clean up use of SDR1 fields.
IBM's "The Programming Environments for 32-Bit Microprocessors":
The HTABMASK field in SDR1 contains a mask value that determines
how many bits from the hash are used in the page table index. This mask
must be of the form 0b00...011...1; that is, a string of 0 bits followed by
a string of 1bits. The 1 bits determine how many additional bits (at least 10)
from the hash are used in the index; HTABORG must have this same number of
low-order bits equal to 0.
IBM's "The Programming Environments Manual for 64-bit Microprocessors" 3.0:
The HTABSIZE field in SDR1 contains an integer value that determines
how many bits from the hash are used in the page table index. This number
must not exceed 28. HTABSIZE is used to generate a mask of the form
0b00...011...1; that is, a string of 0 bits followed by a string of 1-bits.
The 1-bits determine how many additional bits (beyond the minimum of 11)
from the hash are used in the index. The HTABORG must have this same number
of low-order bits equal to 0.
Adjust alignment mask and hash size for ppc64.
Note that the page table does not yet scale with the memory size, and
the secondary hash is not yet used.
v5:
* Move HTABORG mask to header.
* Keep is_ppc64() for now, suggested by Alex.
Merge CONFIG_PPC_64BITSUPPORT handling here so that it behaves as intended,
not recognizing a ppc64 CPU in pure 32-bit mode.
* Stub out hash_page_32() for ppc64 to avoid having to care about it for ppc64.
hash_page_64() is less critical for pure ppc build since the code needs to be
32-bit compatible anyway.
v4:
* Don't redefine hash_page_{32,64} but add TODO comments for renaming.
* Keep and simplify hash_page().
v3:
* Fix shifts. Thanks to Segher and Alex.
* Fix HTABSIZE for 32-bit ppc64: ((2 << 15) - 1) >> 16 happened to be 0,
so that it worked as expected. Avoid underflow, spotted by Alex.
Make this fix available for legacy 64-bit support as well.
* Drop get_hash_size(). It was only used in hash_page_32() and caused
unnecessary conversions between HTABMASK and size.
* Introduce {mfsdr1,mtsdr1} as suggested by Alex.
Note that this changes the volatility for hash_page_64().
* Conditionalize 64-bit support, drop 32-bit support for ppc64.
* Adjust hash size for ppc64.
v2:
* Use HTABSIZE for ppc64, fix HTABMASK usage for ppc.

Having legacy 64-bit support as an option allows users to
disable it and test the 32-bit only version prior to official
removal of legacy 64-bit support.
Fork single-bitness macros EXCEPTION_{PREAMBLE,EPILOGUE}:
Use assembler macros for things that are constant to avoid
; and \, and use preprocessor macros to handle differences.
Adopt QEMU coding style for new code.
Functional changes for ppc64:
* Don't clear MSR in preamble
in order to stay in Sixty-Four Bit Mode.
* Just save the minimum number of registers
since 64-bit code will save the full registers.
* Reserve 48 bytes of stack frame space for ppc64,
according to 64-bit PowerPC ELF ABI supplement 1.9.
* Use rfid via RFI macro.

* Remove inaccurate comment on unused stack location.
* Add explanatory comments for #else and #endif.

Physical address and size were both using two cells instead of one,
and their order was wrong. This would happen to work for RAM < 4 GB,
since the clear high address bits would happen to match the zero-based
memory location. It would indicate a second bank of size zero though.
Switch the value order and use encode-phys in preparation for ppc64.
This tidies the output of the Haiku boot loader.
v2:
* Document TODOs for ppc64, requested by Alex.

Introduce a 0.r word, suggested by Segher.
Optimize r890 by using this helper.
v4:
* Replace ." " by space word, suggested by Segher.

Due to the 64-bit immediate load sequence, the ISI and DSI vectors
are two instructions too long for the respective segment exceptions.
Move the code to the start of the relocated vector region and do a
relative branch there.
v2:
* load() -> LOAD_REG_IMMEDIATE()

When loading the fw_cfg address with just lis, addi sequence,
we get the high address bits as 0xffffffff on ppc64.
Use the full double word immediate load sequence on ppc64.
v2:
* Rename from load() to LOAD_REG_IMMEDIATE() to match Linux.
Suggested by Alex.
* Move to ppc/asmdefs.h for future use elsewhere.

Don't clear the MSR for the pure ppc64 version since it would disable
Sixty Four bit mode as well.
The MMU is supposed to be disabled by default.
