Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

Android Boot Image v1 adds "Recovery DTB" field in image header and
associate payload in boot image itself [1]. Payload should be in
Android DTB/DTBO format [2]. That "Recovery DTB" area should be only
populated for non-A/B devices, and only in recovery image.
Add function to get an address and size of that payload. That function
can be further used e.g. in 'abootimg' command to provide the user a way
to get the address of recovery dtbo from U-Boot shell, which can be
further parsed using 'adtimg' command.

Android Boot Image v2 adds "DTB" payload (and corresponding field in the
image header). Provide functions for its handling:
- android_image_get_dtb_by_index(): Obtain DTB blob from "DTB" part of
boot image, by blob's index
- android_image_print_dtb_contents(): Iterate over all DTB blobs in
"DTB" part of boot image and print those blobs info
"DTB" payload might be in one of the following formats:
1. concatenated DTB blobs
2. Android DTBO format
The latter requires "android-image-dt.c" functionality, so this commit
selects that file for building for CONFIG_ANDROID_BOOT_IMAGE option.
Right now this new functionality isn't used, but it can be used further.
As it's required to apply some specific dtbo blob(s) from "dtbo"
partition, we can't automate this process inside of "bootm" command. But
we can do next:
- come up with some new command like "abootimg" to extract dtb blob
from boot image (using functions from this patch)
- extract desired dtbo blobs from "dtbo" partition using "adtimg"
command
- merge dtbo blobs into dtb blob using "fdt apply" command
- pass resulting dtb blob into bootm command in order to boot the
Android kernel with Android ramdisk from boot image

In new versions of Android Boot Image next fields are added to the
header (and corresponding payloads are added to the image itself):
- v1: Recovery DTBO
- v2: DTB
Account for these new fields in next functions:
1. android_image_get_end(): as v1 and v2 have new payloads in the
image, the calculation of image end address should be extended
correspondingly; this is used e.g. by "bootm" command when booting
the kernel from Android Boot Image
2. android_print_contents(): new fields values in v1 and v2 should be
printed; the result of this function can be seen e.g. in "iminfo"
command
This commit doesn't add the means for working with new payloads in v1
and v2 images (it will be done in further commits), it only updates
existing functions w.r.t. changes in boot image v1/v2.

This allows to use any available compression format with Android boot image
Since not all available compression formats have a magic number we should
explicitly specify type of compression.
For this purpose using uImage format becomes very useful, as this format is
well-known by the community and mkimage tool is already available.
Usage example:
mkimage -A ARM64 -T kernel -C lzma -d Image.lzma out/kernel
At this moment only -C option is handled, but specifying -A and -T options
are recommended for compatibility reasons in the future.
Kernel that compressed with LZ4 can be already used without wrapping into
the uImage, but I recommend wrapping it into the uImage in order to avoid
situations when by some mistake legacy LZ4 is used, that is interpreted as
raw Image and causes CPU to enter Exception Handler without providing any
meaningful explanation to the user.

According to Android image format [1], kernel image resides at 1 page
offset from the boot image address. Grab the magic number from there
and allow U-Boot to handle LZ4-compressed KNL binaries instead of
hardcoding compression type to IH_COMP_NONE. Other compression types,
if needed, can be added later.
Tested on H3ULCB-KF using the image detailed in [2].

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The second area of android image was intended to put a 2nd stage
bootloader but in practice were rarely used (in my knowledge).
An proposal was made to the AOSP to (re)use the second area as the dtb[1],
This patch itself doesn't depend on that proposal being accepted but it won't
be that helpful as well if that proposal won't be accepted. But don't do
any harm as well.

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.
Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

The two tools that create android boot images, mkbootimg and the fastboot
client, set the kernel address by default to 0x10008000.
U-boot always honors this field, and will try to relocate the kernel to
whatever value is set in the header, which won't be mapped to the actual RAM on
most platforms, resulting in the kernel obviously not booting.
All the targets in U-Boot right now will download the android boot image to
CONFIG_SYS_LOAD_ADDR, which means that it will already have been downloaded to
some location that is suitable for execution.
In order to have the kernel booting even with the default boot image kernel
address, if that address is used, just execute the kernel where it is.

This patch makes the following changes:
- Set kernel entry point correctly
- Append bootargs from image to global bootargs instead
of replacing them
- Return end address instead of size from android_image_get_end()
- Give correct parameter to genimg_get_format() in boot_get_ramdisk()
- Move ramdisk message printing from android_image_get_kernel() to
android_image_get_ramdisk()

This patch adds support for the Android boot-image format. The header
file is from the Android project and got slightly alterted so the struct +
its defines are not generic but have something like a namespace. The
header file is from bootloader/legacy/include/boot/bootimg.h. The header
parsing has been written from scratch and I looked at
bootloader/legacy/usbloader/usbloader.c for some details.
The image contains the physical address (load address) of the kernel and
ramdisk. This address is considered only for the kernel image.
The "second image" defined in the image header is currently not
supported. I haven't found anything that is creating this.
v3 (Rob Herring):
This is based on http://patchwork.ozlabs.org/patch/126797/ with the
following changes:
- Rebased to current mainline
- Moved android image handling to separate functions in
common/image-android.c
- s/u8/char/ in header to fix string function warnings
- Use SPDX identifiers for licenses
- Cleaned-up file source information:
android_image.h is from file include/boot/bootimg.h in repository:
https://android.googlesource.com/platform/bootable/bootloader/legacy
The git commit hash is 4205b865141ff2e255fe1d3bd16de18e217ef06a
usbloader.c would be from the same commit, but it does not appear
to have been used for any actual code.
v4:
- s/andriod/android/
- Use a separate flag ep_found to track if the entry point has been set
rather than using a magic value.
