malloc_simple: calloc: don't call memset if malloc failed

2018-08-24T17:20:19+00:00

malloc_simple() can return 0 if out of memory. Don't call memset
from calloc() in this case but rely on the caller checking
the return value.

cmd: Add dtimg command

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

dtimg command allows user to work with Android DTB/DTBO image format.
Such as, getting the address of desired DTB/DTBO file, printing the dump
of the image in U-Boot shell, etc.

This command is needed to provide Android boot with new Android DT image
format further.

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.
