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:

Acording to rockchip, the bootloader message is storaged
in the misc, and the offset address is BOOTLOADER_MESSAGE_BLK_OFFSET
blocks. But the offset address is zero in the normal state.
So add the CONFIG_RKIMG_BOOTLOADER to seperate it.

in the normal boot mode ignores it by passing "skip_initramfs" in the

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.
