c956126a51 fdt: Treat device tree file type like ACPI 
We now have signature check logic in grub which allows us to treat
files differently depending on their file type.

Treat a loaded device tree like an overlayed ACPI table.
Both describe hardware, so I suppose their threat level is the same.

f8d1ad2678 tpm: Fix bug in GRUB2 TPM module 
The value of tpm_handle changes between successive calls to grub_tpm_handle_find(),
as instead of simply copying the stored pointer we end up taking the address of
said pointer when using the cached value of grub_tpm_handle.

This causes grub_efi_open_protocol() to return a nullptr in grub_tpm2_execute()
and grub_tpm2_log_event(). Said nullptr goes unchecked and
efi_call_5(tpm->hash_log_extend_event,...) ends up jumping to 0x0, Qemu crashes
once video ROM is reached at 0xb0000.

This patch seems to do the trick of fixing that bug, but we should also ensure
that all calls to grub_efi_open_protocol() are checked so that we don't start
executing low memory.

d6ca0a90ca verifiers: Core TPM support 
Add support for performing basic TPM measurements. Right now this only
supports extending PCRs statically and only on UEFI. In future we might
want to have some sort of mechanism for choosing which events get logged
to which PCRs, but this seems like a good default policy and we can wait
to see whether anyone  has a use case before adding more complexity.

878398c1a3 efi: Add EFI shim lock verifier 
This module provides shim lock verification for various kernels
if UEFI secure boot is enabled on a machine.

It is recommended to put this module into GRUB2 standalone image
(avoid putting iorw and memrw modules into it; they are disallowed
if UEFI secure boot is enabled). However, it is also possible to use
it as a normal module. Though such configurations are more fragile
and less secure due to various limitations.

If the module is loaded and UEFI secure boot is enabled then:
  - module itself cannot be unloaded (persistent module),
  - the iorw and memrw modules cannot be loaded,
  - if the iorw and memrw modules are loaded then
    machine boot is disabled,
  - GRUB2 defers modules and ACPI tables verification to
    other verifiers.

c79c59f129 lsefimmap: support persistent memory and other UEFI 2.5 features 
This should accompany
	76ce1de740 Translate UEFI persistent memory type

1. Add a string for the EfiPersistentMemory type 14 that was
added in UEFI 2.5.

2. Decode the memory attributes that were added in UEFI 2.5:
* NV (non-volatile)
* MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
  with partial memory mirroring)
* RO (read-only)

3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
values rather than misusing SI power-of-ten units (KB, MB, etc.)

4. The lsmmap command only decodes memory ranges sizes up to GiB scale
units.  Persistent memory ranges will reach into the TiB scale.
Since 64-bit size field supports TiB, PiB, and EiB, decode all of
them for completeness.

5. In the lsefimmap command, rewrite the print statements to
* avoid rounding
* avoid a big nested if/else tree.

For example: In the sixth entry below, the value of 309MB implies
316416KB but is really reporting 316436KB.

Widen the size column to 6 digits to accommodate typical cases.
The worst case value would require 14 digits; if that happens,
let the columns get out of sync.

d43a5ee651 tsc: Use alternative delay sources whenever appropriate. 
PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.

Based on patch by Michael Chang.
