- the partition disk layer takes over the responsibility of slot suffix
appending, we remove relative code to make file clean;
- put android a/b code together and name them to be eary understood,
this makes file esay to read.

- The U-disk boot is only supported from U-Boot, the earlier preloader
doesn't support it;
- MMC1(SD) has higher priority than U-disk;
- Always boot into recovery mode and deliver "usbfwupdate" to cmdline;
- Usb driver may depend on clock/regulator init, so behind of them;
- Suggest to add ./dts/kern.dtb file to promise the kernel dtb always
to be loaded successfully even the native images are all damaged.

For some legacy reasons, rockchip use mkbootimg tool to pack android
images with special pack parameters(SDK version lower than 8.1) to
assign kernel/ramdisk/seconds address and page size.
Android hdr on RK3399 SDK-7.1:
kernel size: 1299808
kernel address: 60408000
ramdisk size: 1e6b80
ramdisk addrress: 62000000
second size: 41c00
second address: 60f00000
tags address: 60088000
page size: 4000
header_version: 0
os_version: e041114 (ver: 1.7.2, level: 2017.4)
name:
cmdline: buildvariant=userdebug
The kernel/ramdisk/seconds address base is not from 0x10000000 and
page size is not 0x800!
This patch makes bootflow to compatible with above legacy packing.

This patch add auto parse the compress format of kernel image.
Then decompress the compressed kernel image for arm64, as for
arm32 zImage, we only need to load it to a higher memory, then
the kernel will handle the decompress itself.
Test on RK3308 AARCH64 mode (Cortex A35 816 MHZ) boot with eMMC:
------------------------------------------------------------------
Format | Size(Byte) | Ratio | Decomp time(ms) | Boot time(ms) |
-------------------------------------------------------------------
Image | 7720968 | | | 488 |
-------------------------------------------------------------------
Image.lz4 | 4119448 | 53% | 59 | 455 |

Note: the boot time is counted from first ddr init log to first Kernel log.

The kernel image follows the header(default 0x800) in boot.img, we need to fix
the load address for boot.img so that kernel image can align to 0x80000 as
required by ARM64 kernel booting.

- If CONFIG_ROCKCHIP_RESOURCE_IMAGE is enabled, try to get dtb from resource

The bootavb flow v bootload android system
with avb.And bootavb flow n bootload android
system as usual.

The android_bootloader_control struct defined in bootloader_message.h
stored the A/B metadata used to decide which slot should we use to boot
the device. This patch implements the bootloader side of the slot
selection in a new "android_ab_select" command which decides the
current slot and updates the metadata as needed.
Bug: 32707546
Test: Booted a rpi3, updated to the other slot.

The new "boot_android" command simply executes the Android Bootloader
flow. This receives the location (interface, dev, partition) of the
Android "misc" partition which is then used to lookup and infer the
kernel and system images that should be booted.
Bug: 32707546
Test: Booted a rpi3 build with Android Things.
