[U-Boot] [PATCH 00/12] ARM: tegra: Share cboot code with Tegra210

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

Code to support chainloading by nvtboot was introduced along with
Tegar186 support. Since then, support for chainloading U-Boot has been
extended to other Tegra SoC generations. This series of patches makes
this code more widely available so that it can be reused.

Also, the early bootloader responsible for chainloading U-Boot is called
cboot nowadays, so the files and functions are renamed to reflect that.

Patches 1-6 are preparatory changes that guard various bits of code and
header includes with a Kconfig symbol, which makes it easier to support
Tegra186 and earlier generations from a larger body of code.

Patch 7 makes the save_boot_params() prototype more generic so that it
can be reused on 64-bit ARM platforms.

Patch 8 is the bulk of the series and moves the nvtboot code to a more
central location and renames it.

Patches 9-12 build on top of this to extend the cboot functionality with
additional features.
