b2846490c3 vboot_api: Remove unused VB_SCREEN constants
Some of the defined screens have never been used or we've stopped using
them a while ago. Remove the respective constants to make it clearer
that callers of the library are not expected to handle them.

98616d79c6 firmware: Prune down old region API
The region API was a way for firmware and kernel verification to get
at various blocks of caller-provided data.  In practice, we only used
it internally as a way to get at parts of the GBB.  Prune it down to
access only the bits of GBB we still need, from the buffer we already
know we have.

In the long run we should use the same vb2ex_read_resource() API that
vb2 firmware verification does, but that should be done in a follow-up
CL since it'll need to be coordinated with support in depthcharge.

No change in functionality.

79c1c6194b firmware: Include vb1 shared data in vb2 struct
Currently, firmware verification uses entirely vb2 structs, including
vb2_shared_data.  This goes through an ugly translation to the old vb1
VbSharedData to pass it to depthcharge.  The vboot kernel verification
maintains an equally ugly translation back to the vb2 struct
internally.

Eventually, we want to get rid of all that and use vb2 all the way
down to what crossystem picks up from the OS.

But before we can do that, we need to finish translating kernel
verification code to use the new vb2 structs.  This is a step on that
path, using vb2_shared_data equivalents where present and hiding the
old vb1 shared data struct as a member of vb2_shared_data so at least
the vboot functions don't need to pass around cparams to get at it.

This will be followed by more CLs which convert more vboot internals
to use vb2 structs directly, and eventually coreboot/depthcharge CLs
which pass the vb2 structs from firmware verification directly to
kernel verification.

No change in functionality.

de818cc08f firmware: simplify audio
Vboot firmware previously supported a rather complex audio looping
library.  Our original intent was to allow developers to flash a
custom beep sequence / tune as an easter egg.  We never fully
supported that, but the code to allow it lived on.  Get rid of that.

Vboot also previously made no assumptions about the frequency of
VbExGetTimer(), which was only used by the vboot_audio library.  So it
spent 10ms every boot measuring the frequency.  Which is silly now,
because depthcharge implements that as a microsecond timer.  Get rid
of that measurement and define the timer as a microsecond timer.

it has access to the GBB flags via the vb2 context.  Refactor all

527ba810ef 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.
