help
Enable the emmcboot command for dual-bank boot from eMMC.
This is a legacy boot format used on this board for many years.
It implements a boot system with two image banks and automatic
fallback on boot failures. The boot order depends on a reboot
tracking counter (nrboot):
- If healthy: try Bank1 (newer) first, then Bank0 (stable)
- If degraded (>= 4 failures): try Bank0 first, then Bank1
Requires image_addr and fdt_addr environment variables to be set.

Enable the fbxserial command to read and display device
serial information from eMMC. This includes:
- Device serial number (type, version, manufacturer, date, number)
- MAC address (used to set ethaddr environment variables)
- Bundle information (if present)
The serial info is stored at a fixed offset in the eMMC user area.
Subcommands:
- fbxserial show: display serial info (default)
- fbxserial init: initialize ethaddr from serial info
Use CONFIG_PREBOOT="fbxserial init" to auto-initialize at boot.
