Samuel Holland 0770ea1178 tools: mkimage: Add Allwinner TOC1 support 
TOC1 is an container format used by Allwinner's boot0 that can hold
multiple images. It supports encryption and signatures, but that
functionality is not implemented, only the basic "non-secure" subset.

A config file is used to provide the list of data files to include. Its
path is passed as the argument to "-d". It contains sections of the
following form:

  [name]
  file = /path/to/file
  addr = 0x12345678

Specific well-known names, such as "dtb", "opensbi", and "u-boot", are
used by the bootloader to distinguish the items inside the image.

Cover-letter:
tools: mkimage: Add Allwinner TOC1 support

The SPL port for the Allwinner D1 RISC-V SoC will probably take a while
longer than porting U-Boot proper, as none of the relevant drivers are
set up for DM in SPL. In the meantime, we are using[1][2] a fork[3] of
Allwinner's boot0 loader, which they also call "spl" in their BSP. boot0
uses this TOC1 image format.

The vendor tools for generating TOC1 images require a binary config file
generated by their FEX compiler. Instead of trying to support that, I
made up a simple human-readable config file format. I didn't see any
existing platform-agnostic parser for multi-image containers in mkimage.

I am sending this as RFC because it is only of temporary/limited use.
It only works with one specific fork of boot0 which was modified to
"behave" (the the original vendor version monkey-patches a custom header
inside the U-Boot image during boot). So it will be obsolete once U-Boot
SPL is ported. And it is Yet Another Image Format. On the other hand, it
does work, and it is currently being used.

# A note on target vs host configuration:
#
# Host tools can be used across multiple targets, or different configurations
# of the same target. Thus, host tools must be able to handle any combination
# of target configurations. To prevent having different variations of the same
# tool, the tool build options may not depend on target configuration.
#
# Some linux distributions package these utilities as u-boot-tools, and it
# would be unmaintainable to have a different tool variation for each
# arch or configuration.
#
# A couple of simple rules:
#
# 1) Do not use target CONFIG_* options to enable or disable features in host
# tools. Only use the configs from tools/Kconfig
# 2) It's okay to use target configs to disable building specific tools.
# That's as long as the features of those tools aren't modified.
#
# Enable all the config-independent tools
