fb267154d2 Fix indentation in firmware and host libs
vboot_reference originally used 2-space indentation, rather than
kernel-style tabs.  This makes it painful to maintain given that newer
source files are kernel-style.

Re-indent the files that need it, and reflow comments.

No functionality changes.

6c18af5017 cgpt: add support for managing the legacy boot gpt bit
Bit 2 in the GPT partition attributes has been allocated as the legacy
bios boot (equivalent to the "active" or "boot" flag in MBR).  If we
try to boot images on newer x86 systems, syslinux dies because it can't
find any GPT partition marked bootable.

Update the various parts of cgpt add & show to manage this bit.  Now we
can run:
	cgpt add -i 12 -B 1 chromiumos_image.bin
And the EFI partition will be marked bootable.

8228f47dfd cgpt: Add cgpt legacy parameter to set primary GPT signature to IGNOREME
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).

ab89959180 vboot: cgpt: Treat drive_path as the GPT storage
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.

a2d72f70c1 vboot: cgpt: Refer to partition entries by entries_lba.
This CL accesses the partition entry array through its header's
entries_lba value.

Previously, we assume the primary entry array lies on third sector, and
the secondary array lies (1 + 32) sectors from disk end. This assumption
was fine, even Wikipedia assumed the same.

But in order for us to support writing boot code to the third sector (as
required by some Freescale board), the primary entry array must be moved
to another location. Therefore, we must use "entries_lba" to locate the
arrays from now on.

494646dbad Fix some issues with LBA vs byte offsets
In several places the existing code assumes LBA, but was improperly converted
to use byte offsets, so multiply by the sector size to correct it and maintain
the same interface between MTD & GPT.

Also, since we will need to cgpt create on /dev/fts, which isn't a stat()able
device, allow providing the disk size on the commandline.

fa6b35c1ff Refactor CgptAdd and CgptPrioitize to remove gpt-specific code
- Refactor cgpt_prioitize.c to completely remove gpt-specific code.
- Refactor cgpt_add.c to isolate gpt-dependence to one helper function
and the backup/restore logic
- Change several common apis to take a struct drive* rather than a GptData*,
this provides a path to cleanly implement mtd versions
