From: Stefan Agner stefan.agner@toradex.com
Add support for distro boot. This is especially helpful for external devices. There is a global boot command which scans a predefined list of boot targets: run distro_bootcmd
As well as direct boot commands such as: run bootcmd_mmc0 run bootcmd_usb run bootcmd_dhcp ...
Refer to doc/README.distro fo details.
While at it also re-order boot command macros as well as the CONFIG_EXTRA_ENV_SETTINGS.
