help
This simulates the interface to a bootloader.
Bootloader environment is just maintained in RAM
and lost when SWUpdate exits.

This is the file described in U-Boot documentation
in the tools directory. It tells where the U-Boot
environment is saved.

string "U-Boot Initial Environment file"
depends on UBOOT
default "/etc/u-boot-initial-env"
help
This is the file with the initial environment delivered
with the bootloader. It is used by SWUpdate if no environment
is found on the storage.

config BOOTLOADER_CBOOT
bool "NVIDIA Tegra Cboot"
depends on HAVE_LIBTEGRABOOT_TOOLS
help
Support for NVIDIA's cboot used on some Tegra platform. Tegra
uses different bootloader, depending on the SOC and on the release
provided by vendor. Some SOCs (associated with some releases) are still
using U-Boot (Jetson Nano, TX, TX2), some of them are using Cboot (Xavier),
and some of them rely on UEFI. This adds support for cboot.

help
Default bootloader interface to use if not explicitly
overridden via configuration or command-line option
at run-time.

Use EFI Boot Guard as default bootloader interface.
Note: Make sure the environment modification shared
library https://github.com/siemens/efibootguard (including
dependencies) is installed on the target system.

config BOOTLOADER_STATIC_LINKED
bool "Bootloader interface static linked"
help
Link statically the interface to the bootloader. In case of distros,
more interfaces are available at the same time and SWUpdate checks
at runtime and loads the interface via dlopen(). This is available
with glibc and dlopen support. For other system, the interface can be linked
statically.

status for, e.g., communicating it to SWUpdate after
a reboot.
