The first patch adds support for the IMX7 to load image from SD/MMC similar to
IMX6 and IMX8.
The second patch adds support for Atlas Copco's IXB tool which comes with
IMX7D, 1GB lpddr2 and has most of the interfaces supported by the SoC.
This patch also shows booting IMX7 without a static DCD file which allows
to have a single barebox image on multiple revisions of the same board
(different memory chips).
The _no_ DCD file part is an adaptation for ac-sxb from zii-imx6q-rdu2.

Empty initcall serves no purpose, just drop it if you're leaving
it empty. If you want to add something here, I'd suggest registering
a barebox update (bbu) handler for easy barebox update.

You can use a compressed dtb (__dtb_z with CONFIG_ARM_COMPRESSED_DTB)
to reduce your barebox' size.

You can drop this node and include imx7d-ddrc.dtsi instead. When the driver
is enabled, barebox will then read out the memory size from the DDR controller,
so you can use the same device tree for multiple memory sizes.

dts/ is regularly synchronized with the Linux device trees. We don't accept
patches against this directory. Either
1) upstream your device trees to Linux and wait for them to appear here
2) add your device trees in arch/arm/dts (possibly as dtsi, so you can still
keep the barebox-specific nodes separate)
