af7a34acfd fwu: fix fwu_get_image_index interface
The capsule update uses the DFU framework for updating
storage. fwu_get_image_index() currently returns the
image_index calculated by (dfu_alt_num + 1), but this is
different from the image_index in UEFI terminology.

Since capsule update implementation calls dfu_write_by_alt
function, it is better that FWU returns the dfu_alt_num.

f72d0d4a2f event: Convert existing spy records to simple
Very few of the existing event-spy records use the arguments they are
passed. Update them to use a simple spy instead, to simplify the code.

Where an adaptor function is currently used, remove it where possible.

95311f7a19 fwu: Initialize global fwu library state during CI test
The current CI test worked by sheer luck, the g_dev global pointer
in the fwu library was never initialized and the test equally well
failed on sandbox64. Trigger the main loop in sandbox tests too to
initialize that global state, and move the sandbox specific exit
from fwu_boottime_checks after g_dev is initialized.

395ab12b5f fwu: mtd: Fix dfu_alt_info generation for 2 images per bank
Code rewrites the last char of size with adding &. It is visible from
dfu_alt_info print before this patch:

Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
8000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'

And after it:
Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
80000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'

Size for bank0 and bank1 must be the same because it is the same image.

a6dd927f5b fwu: Allow code to properly decode trial state
Current code after capsule update (mtd write) is not changing active_index
in mdata to previous_active_index.
On the reboot this is shown but showing message
"Boot idx 1 is not matching active idx 0, changing active_idx"
which is changing active_idx and writing mdata to flash.

But when this message is visible it is not checking which state that images
are. If they have acceptance bit setup to yes everything is fine and valid
images are booted (doesn't mean the latest one).
But if acceptance bit is no and images are in trial state in_trial variable
is never setup. Which means that from new flashed image stable image can be
rewritten because in_trial is not setup properly.

4898679e19 FWU: Add FWU metadata access driver for MTD storage regions
In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, on a separate
region. Add a driver for reading from and writing to the metadata
when the updatable images and the metadata are stored on a raw
MTD region.
The code is divided into core under drivers/fwu-mdata/ and some helper
functions clubbed together under lib/fwu_updates/

8679405241 FWU: Add support for the FWU Multi Bank Update feature
The FWU Multi Bank Update feature supports updating firmware images
to one of multiple sets(also called banks) of images. The firmware
images are clubbed together in banks, with the system booting images
from the active bank. Information on the images such as which bank
they belong to is stored as part of the metadata structure, which is
stored on the same storage media as the firmware images on a dedicated
partition.

At the time of update, the metadata is read to identify the bank to
which the images need to be flashed(update bank). On a successful
update, the metadata is modified to set the updated bank as active
bank to subsequently boot from.

7e9814cc6c FWU: Add boot time checks as highlighted by the FWU specification
The FWU Multi Bank Update specification requires the Update Agent to
carry out certain checks at the time of platform boot. The Update
Agent is the component which is responsible for updating the firmware
components and maintaining and keeping the metadata in sync.

The spec requires that the Update Agent perform the following checks
at the time of boot
* Sanity check of both the metadata copies maintained by the platform.
* Get the boot index passed to U-Boot by the prior stage bootloader
  and use this value for metadata bookkeeping.
* Check if the system is booting in Trial State. If the system boots
  in the Trial State for more than a specified number of boot counts,
  change the Active Bank to be booting the platform from.

Call these checks through the main loop event at the time of platform
boot.

7d6e2c54b7 FWU: Add helper functions for accessing FWU metadata
Add weak functions for getting the update index value and dfu
alternate number needed for FWU Multi Bank update
functionality.

The current implementation for getting the update index value is for
platforms with 2 banks. If a platform supports more than 2 banks, it
can implement it's own function. The function to get the dfu alternate
number has been added for platforms with GPT partitioned storage
devices. Platforms with other storage partition scheme need to
implement their own function.
