Now that we have support for the IGNOREME signature in cgpt, we need a
way to set it on an existing disk. The easiest option is to shoehorn
this into the cgpt legacy command, because that's already made to modify
GPT header signatures (really, it would be nice to rename it to cgpt
signature or something, but let's not break existing uses for now).

This patch makes cgpt aware of a special "IGNOREME" GPT header signature
string that may appear in either the primary or the secondary GPT and
cause cgpt (and other cgptlib clients) to completely ignore that GPT. It
will continue to function correctly for all other purposes (using the
data from the non-ignored GPT), but never write any data back to the
ignored GPT.

The point of having two GPTs is to always have a known good one if one
of them gets corrupted. One of the most obvious ways that could happen
is if the write stopped half-way through (e.g. due to a crash or random
power loss).
Unfortunately, the way we currently save modified GPTs can leave both
copies invalid if we stop writing at just the wrong time. Since a GPT
header contains a checksum over the GPT entries, we need to write both
the header and entries for one GPT (and make sure they're synced to
disk) before we start writing the other.

This patch reinstates the external GPT support which was previously
committed and reverted. Improvements since last time include:
- Cleaned-up internal interface based on code review
- Function correctly on legacy bootloaders (e.g., depthcharge before
NAND-related patches are added)
- Better comments
- Treat new field values = 0 -> not use new feature
- Tests are added to ensure external GPT flag is passed down properly
The original commit had change-id
I5a77e417aea8ee9442d18c200d1b073aa5375ecf
Its commit message is reproduced below, and then an additional test.
----
To support an external GPT, disks have two new attributes:
- A binary flag indicating whether the GPT is in the same address
space as the payloads or a separate one.
- The number of sectors of the streaming portion of storage, as
opposed to the portion containing the GPT.
These have been added elsewhere to GptData (in cgptlib) and BlockDev
(in depthcharge). This patch adds the plumbing between those, including
in the DiskInfo interface between the firmware and vboot.

The standard says that entries table must be at least 16384 bytes. On
some of our devices, the NOR section is only 8 KiB and used to store
both primary and secondary tables. On this device, we can only store 24
entries.
Therefore, this CL adds support for non-standard entry table. It adjusts
the MIN_NUMBER_OF_ENTRIES to 16, and replaces GPT_ENTRIES_SECTORS with
CalculateEntriesSectors.

The dev_debug_vboot program can sometimes interfere with
automated firmware testing because it takes too long to read the
BIOS flash. Limiting the sections of flash that are read may
help, but in some cases skipping this program entirely may be
better.
This CL does three things:
1. dev_debug_vboot will read only some sections of the BIOS
flash, falling back to reading the whole thing only if it
fails at that.
2. dev_debug_vboot will source /etc/default/vboot_reference if it
exists. Putting DEV_DEBUG_FORCE=1 in that file will prevent
dev_debug_vboot from reading the flash at all unless it's
invoked with --force option.
3. The Makefile will create the /etc/default/vboot_reference file
in the install directory, setting DEV_DEBUG_FORCE to the value
in effect at build time. This will let a future CL change the
default behavior for each target.
BUG=chromium:438854
BRANCH=none
TEST=manual
Built and tested on Samus. /etc/default/vboot_reference was
present, containing "DEV_DEBUG_FORCE=". The dev_debug_vboot
script ran normally.
Manually changing /etc/default/vboot_reference to contain
"DEV_DEBUG_FORCE=1" and rebooting caused dev_debug_vboot to stop
before reading the BIOS flash.
I also manually forced various flashrom invocations to fail to
test each part of the new flow.

Now that lib20 and lib21 are distinct, they can have overlapping
struct names. This will be cleaner in the long run, since vboot 2.0
(lib20) is just a temporary stepping stone to vboot 2.1 (lib21). It
would be a shame to need to carry around the overhead of that extra
digit forever.
No functional changes, just a lot of renaming.

This is part 4 of a series of changes to rearrange the vboot2 library
so that it's possible to start using the new-style data structs. This
change moves knowledge of the old vboot1 data structs into lib20; 2lib
now contains only code which is common to both vboot2.x libraries
(that is, code which is data structure version agnostic).
No functional changes; just rearranging code and tests.

At one point I thought I'd be able to support both vboot1 and vboot2.1
data structures and dynamically determine which verification path to
run. But space limitations on current platforms (e.g. pinky) mean
that's not feasible. Remove this vestigal support, so that it's
easier to make a clean break to the new data structures on appropriate
platforms.

This commit adds a new VbInit() flag which will indicate that it is
being called before option roms are loaded and can therefore respond
to the VbNv flag without needing an immediate reboot.
When the BIOS calls VbInit() in firmware it may not yet know if the
system is in developer mode if there is a virtual developer mode
switch, instead it relies on the VbNv flag that is prepared by VbInit().
So this new flag only affects VbInit() checks itself, the later checks
still do the right thing because OPROM_LOADED can be set based on the
VbNv value that is set by VbInit().

This reverts commit 5040a945dfd0dd305d3ca8e923b8bf0bd5c6528e.
This patch breaks booting any image (both fixed and

non-NAND board?). By the power vested in me through the
office of ChromeOS tree sheriff (well, five hours early

To support an external GPT, disks have two new attributes:
- A binary flag indicating whether the GPT is in the same address
space as the payloads or a separate one.
- The number of sectors of the streaming portion of storage, as
opposed to the portion containing the GPT.
These have been added elsewhere to GptData (in cgptlib) and BlockDev
(in depthcharge). This patch adds the plumbing between those, including
in the DiskInfo interface between the firmware and vboot.

Previously, "cgpt" called out to "flashrom" directly to read and write
NOR area. This CL removes that dependency and always treats "drive_path"
as the storage of GPT structs. This makes it consistent that whatever
device that cgpt reads from or writes to is always the device that
stores GPT structs. We only need to pass in the size of the drive that
contains the partitions, but we do not need to access to that drive.
More information is in the bug.

This CL allows the GPT headers and partition entry arrays to be stored
in a NOR flash device. Instead of treating both the NOR and NAND devices
as one (in a sandwich way), this CL writes and reads the GPT structs
independently of the actual device that houses the partitions.
Therefore, the first usable LBA of the partitions will be at 0, and the
last usable LBA is at the end of the NAND.
+------------------------+
| NOR houses GPT structs |
+------------------------+
|
0 | Index into
v v
+------------------------+
| NAND houses partitions |
+------------------------+
Note that the "my_lba", "alternate_lba", "entries_lba" in the GPT headers
are no longer meaningful.
Consumers of cgptlib will have to set "stored_on_device" to either
GPT_STORED_ON_DEVICE or GPT_STORED_OFF_DEVICE, and "gpt_drive_sectors"
to the number of 512-byte sectors available to store GPT structs.
The NOR read and write operations are done by "flashrom".

Storing nvram in SPI Flash becomes more and more popular. Retrieving
it takes quite a while due to various flashrom issues. While flashrom
still needs to be improved to minimize its running time, a good speed
up can be achieved by caching the nvram contents in crossystem.
The cache is invalidated each time nvram is written (this could be
optimized by updating the local copy, but probably is not worth the
extra effort).

When a work buffer is passed to a function, and duplicated inside that
function, allocations made against the duplicate are automatically
freed when the duplicate goes out of scope. Make that explicit in the
comments. And pass in const struct workbuf * instead of struct
workbuf *, to make it clear that the passed-in work buffer pointer is
not being altered by the function.
Also, comment that the value of min_offset becomes undefined if
vb2_verify_common_member() or vb2_verify_common_subobject() fails.
