[PATCH v5 0/3] sunxi: TOC0 image type support

[Samuel Holland]

This series adds support for the TOC0 image format used by the Allwinner
secure boot ROM (SBROM). This series has been tested on the following
SoCs/boards, with the eFuse burnt to enable secure mode:
 - A50: Ainol Q88 Tablet
 - A64: Pine A64 Plus
 - H5: Orange Pi Zero Plus
 - H6: Pine H64 Model B
 - H616: Orange Pi Zero 2

This time I also tested it on boards that are not switched to secure
mode (with A64, H3, and H5).

Due to both series changing Makefile.spl, the last patch depends on:
https://patchwork.ozlabs.org/project/uboot/list/?series=267136
I have seen no comments on that series, so I assume that it is ready to
merge along with this one.

Changes in v5:
 - Rebased on top of suniv platform additions
 - Took care of additional hardcoded offset in SPL SPI code
 - Dropped controversial Kconfig patch

Changes in v4:
 - Do not select TOOLS_LIBCRYPTO anywhere

Changes in v3:
 - Removed TOOLS_LIBCRYPTO selection for sunxi, since most boards
   do not need it
 - Added __packed to all new "ABI" structs
 - Added entry to MAINTAINERS for sunxi tools
 - Fixed offset of magic passed to memcmp
 - Refactored functions to not return pointers (fixes ambiguous NULL)

Changes in v2:
 - Moved certificate and key item structures out of sunxi_image.h
 - Renamed "main" and "item" variables for clarity
 - Improved error messages, and added a hint about key generation
 - Added a comment explaining the purpose of the various key files
 - Mentioned testing this code on A50 in the commit message
 - Moved SPL header signature checks out of sunxi_image.h
 - Refactored SPL header signature checks to use fewer casts
 - Rebase on top of Icenowy's RISC-V support series
 - Rename Kconfig symbols to include the full image type name
