u-boot.git/common/image-android-dt.c, branch master

Create a new boot/ directory

2021-11-12T00:01:56+00:00

Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.

Most files with 'boot' or 'image' in them are moved, except:

- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing

Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

dt_entry_count [1]. Forbid that [2].

common: Add support for Android DT image

2018-08-20T11:21:29+00:00

Android documentation recommends new image format for storing DTB/DTBO
files: [1]. To support that format, this patch adds helper functions for
Android DTB/DTBO format. In image-android-dt.* files you can find helper
functions to work with Android DT image format, such us routines for:
    - printing the dump of image structure
    - getting the address and size of desired dtb/dtbo file

This patch uses dt_table.h file, that was added in commit 643cefa4d848
("Import Android's dt_table.h for DT image format") by Alex Deymo.
