The old boot control logic and misc data struct is based on the
'external/avb/libavb_ab' library which is already marked as
deprecated and won't be maintained by google anymore:commit 37f5946d0e1159273eff61dd8041377fedbf55a9

Date: Wed Sep 20 15:02:32 2017 -0400Deprecate libavb_ab and bootctrl.avb code.
This code was already marked as experimental in anticipation of being
removed in the future. Officially deprecate it and set Jun 1 2018 as
the date it will be removed. This should give users of the code ample
time to fork/migrate.To keep using the code AVB_AB_I_UNDERSTAND_LIBAVB_AB_IS_DEPRECATED
must be defined.The reason for deprecating this code is twofold:
- Its policy was optimized for devices without a display with
e.g. automatic fallback to the other slot if a slot fails to
boot. Since most A/B stacks in Android devices don't work this
way this code is confusing.- There are no known active users, no good test coverage for the
bootctrl.avb code, and no plans to use it.When the code is removed we'll provide an easy transition path by
keeping (but renaming) the |ab_ops| member in AvbOps.Change-Id: Id5e090a2048076d36ccca2e1c4cb55e226b8b43d
Google has provided a new boot control v1.1 implementation under
'hardware/interfaces/boot/1.1/default' which uses a new misc data struct defined
in the 'include/android_bootloader_message.h'. This commit adds a new boot control
implementation in bootloader, which combines the new misc data struct and inherit
some flow in 'libavb_ab', the old 'libavb_ab' library will be removed.Test: boot/slot switch/retry count test on single&dual bootloader.

Decrypt and verify the secure credential in keymaster TA, unlock
operation can only be allowed after secure credential verify pass.Since the mppubk can only be generated on hab closed imx8q, so secure
unlock feature can only supported when hab is closed.Test: secure unlock credential verify on hab closed imx8mm_evk.

The A/B slot selection is moved to spl, it may lead to hang
if no bootable slots found. The only way to recover the board
is re-flash images with uuu tool, which is quite inconvenient
for some customers who can't enter serial download mode.This patch will set "spl recovery mode" which will give us a
chance to re-flash images with fastboot commands.Test: Enter spl recovery mode and flash images when no bootable
slots found.Change-Id: I31278f5212bde7609fe2f49e77b3849e92c0c516

Add new keymaster commands to get Manufacure Production key (mppubk).
Since the mppubk can only be generated in OEM CLOSED imx8q board, so
we can only use this command when the board is HAB/AHAB closed.Commands to extract the mppubk:
* $fastboot oem get-mppubk
* $fastboot get_staged mppubk.binTest: Generate and dump the mppubk.bin
