kernel flags: Pass back kernel premable flags in kparams
Kernel preamble flags are set by the signer for passing hints about
the image. Read these flags from the preamble and pass it back to the
caller in kparams structure.
BUG=chrome-os-partner:35861
BRANCH=None
TEST=Compiles and boots to kernel prompt for both CrOS image and bootimg.

vboot: Plumb the two disk sizes and external GPT param through
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.
BUG=chromium:425677
BRANCH=none
TEST=Interactively wrote the GPT with cgpt and observed the following
boot with depthcharge to read the GPT from SPI and then read from
the proper locations in NAND flash.
TEST=make runalltests passes.
TEST=boots from USB with depthcharge from HEAD.

Revert "vboot: Plumb the two disk sizes and 'gpt on device' param through"
This reverts commit 5040a945dfd0dd305d3ca8e923b8bf0bd5c6528e.
This patch breaks booting any image (both fixed and
removable) on Veyron_Pinky (and presumably every other
non-NAND board?). By the power vested in me through the
office of ChromeOS tree sheriff (well, five hours early
but whatever) it is hereby reverted!
BUG=chromium:425677
BRANCH=none
TEST=Can successfully boot on Veyron_Pinky again.

Implementation of Region API
At present reading data from storage in Vboot is a little fragmented. For
the firmware image, we expect the boot loader to handle this. For the disk
we have a block-level API. For the GBB (which also sits in the firmware
image) we expect the entire thing to be read before Vboot is called.
Add the concept of a region, and an API to read from a region. At present,
and most pressing, is reading from a GBB region. In the future this could
be extended to other parts of the firmware or even the disk.
Move all access to the GBB into this API so that the boot loader can provide
either a GBB region in one large contiguous chunk, or a function to deal with
read requests from vboot.
The call to VbExRegionRead() is behind a flag since not all boot loaders
support it yet.
The main change for boot loaders which don't support this new API is that
vboot will do more behind the scenes. For example, it will allocate memory
for chunks of data that it reads from the GBB, rather than just accessing it
directly. This approach is considerably simpler than trying to pass char **
everywhere and have vboot decide whether something needs to be allocated or
not.
The tests are updated, mainly to include setting up a GBB structure
accessible from VbCommonParams, which is now required by the firmware and
kernel functions. In normal operation this is set up at the start of
VbLoadFIrmware() and VbSelectAndLoadKernel() but for tests which call
children of these functions directly, the GBB structure must be set up
manually by the test.
