The fdt must be named of "kernel.dtb", and it's saved
in the root dir of the oem partition.

If user get the kernel fdt into the independent partition
which is the ext4 filesystem, we can use this api to load
fdt.

In file boot_android.c, we use some functions
belong to common/android_bootloader.c. BUt these
functions attribute are static. So we modify these
functions used in the boot_android.c.
And android_avb_boot_flow is added to boot a/b
android system.

Android kernel image format can include an initramfs image in the same
kernel partition. This patch passes the initramfs to the kernel, which
in the normal boot mode ignores it by passing "skip_initramfs" in the
command line.

Test: `am broadcast -a android.intent.action.MASTER_CLEAR` factory
reseted the device.

When concatenating the strings to form a new command line in the
android bootloader flow, the null-terminator was placed one byte after
the end of the allocated string.
Bug: None
Test: booted a rpi3.

In order to support booting from either slot, this patch passes the
slot name from the command line.

An Android Bootloader must comply with certain boot modes and change
the kernel command line accordingly. This patch introduces the Android
boot mode concept which determines whether the device should boot to
one of the following:
* recovery: which should boot to the recovery image,
* bootloader: which should boot to the "bootloader" (fastboot) and
* normal: which should boot to the system image.
The boot mode is determined in part by the Boot Control Block (BCB)
which is stored at the beginning of the "misc" partition. The BCB
is defined in the "bootloader_message.h" file in AOSP, now copied
here as android_bootloader_message.h with minor modifications.
This patch implements the basic boot flow that loads and boots an
Android kernel image assuming an A/B device which implies that it uses
boot as recovery (BOARD_USES_RECOVERY_AS_BOOT in the BoardConfig.mk).
This means that the recovery image shares the same kernel with the
normal boot system image, but stores the recovery image as a ramdisk
which is not used in normal mode.
Among the limitations, this patch doesn't implement the A/B slot
selection, it only boots from the slot "a".

Test: Booted a rpi3 with this flow.
