Perform sychronization (by "isb" barrier) after TTB is set.  This
is done to ensure that TLB invalidation always executes after
TTB modification and operates on valid CP15 data (per specification).

4ddc017276 When changing the sd bus clock divisor, clear just the bus clock enable bit
before changing the divisor bits in the register.  We were writing a zero
to the register, which clears the enable, but also cleared the divisor bits
at the same time.  That's a violation of the sdhci spec, which says the
divisor can only be changed when the clock is disabled.  This has worked
okay on most hardware for years, but the TI OMAP controller would misbehave
after changing the divisor improperly.

ef3c56a250 Various fixes to the ti_sdhci driver, mostly to make it work on Pandaboard.
- Don't allow high-speed mode on OMAP4 due to hardware erratum.
 - Check the proper bit in the status register when waiting for the
   controller to come out of reset.
 - Add handling for the "non-removable" fdt property by always returning
   "card is present" status.
 - Add the non-removable property for the MMC card on a Beaglebone Black.
 - Add the non-removable property for Pandaboard as a workaround.

For Pandaboard the card detect pin is handled by the twl6030 fpga device
which gets an interrupt on pin change and then has to query the fpga
for the actual status.  We don't have code to do that yet.

8c00aba8c4 Support UEFI booting on amd64 via loader.efi
This is largely the work from the projects/uefi branch, with some
additional refinements.  This is derived from (and replaces) the
original i386 efi implementation; i386 support will be restored later.

Specific revisions of note from projects/uefi:

r247380:

  Adjust our load device when we boot from CD under UEFI.

  The process for booting from a CD under UEFI involves adding a FAT
  filesystem containing your loader code as an El Torito boot image.
  When UEFI detects this, it provides a block IO instance that points at
  the FAT filesystem as a child of the device that represents the CD
  itself. The problem being that the CD device is flagged as a "raw
  device" while the boot image is flagged as a "logical partition". The
  existing EFI partition code only looks for logical partitions and so
  the CD filesystem was rendered invisible.

  To fix this, check the type of each block IO device. If it's found to
  be a CD, and thus an El Torito boot image, look up its parent device
  and add that instead so that the loader will then load the kernel from
  the CD filesystem.  This is done by using the handle for the boot
  filesystem as an alias.

  Something similar to this will be required for booting from other
  media as well as the loader will live in the EFI system partition, not
  on the partition containing the kernel.

r246231:

  Add necessary code to hand off from loader to an amd64 kernel.

r246335:

  Grab the EFI memory map and store it as module metadata on the kernel.

  This is the same approach used to provide the BIOS SMAP to the kernel.

r246336:

  Pass the ACPI table metadata via hints so the kernel ACPI code can
  find them.

r246608:

  Rework copy routines to ensure we always use memory allocated via EFI.

  The previous code assumed it could copy wherever it liked. This is not
  the case. The approach taken by this code is pretty ham-fisted in that
  it simply allocates a large (32MB) buffer area and stages into that,
  then copies the whole area into place when it's time to execute. A more
  elegant solution could be used but this works for now.

r247214:

  Fix a number of problems preventing proper handover to the kernel.

  There were two issues at play here. Firstly, there was nothing
  preventing UEFI from placing the loader code above 1GB in RAM. This
  meant that when we switched in the page tables the kernel expects to
  be running on, we are suddenly unmapped and things no longer work. We
  solve this by making our trampoline code not dependent on being at any
  given position and simply copying it to a "safe" location before
  calling it.

  Secondly, UEFI could allocate our stack wherever it wants. As it
  happened on my PC, that was right where I was copying the kernel to.
  This did not cause happiness. The solution to this was to also switch
  to a temporary stack in a safe location before performing the final
  copy of the loaded kernel.

c8912fcbdf Correct a PCI enumeration bug introduced in r264011
Ensure that first_func is set to 0 on every iteration of the PCI slot
enumeration loop after the first.  There is a continue statement that would
cause first_func to stay at 1 any PCI device where slot 0 has no functions
until we find a slot that does have a function.  This would cause us to
not enumerate the first PCI function on the device.

Credit to markj@ for spotting the bug.
