bdinfo - print Board Info structure
Usage:
bdinfo
=>
The
bdinfo command (short:
bdi)
prints the information that U-Boot passes about the
board such as memory addresses and sizes, clock frequencies,
MAC address,
etc. This information is mainly needed to be passed to the Linux
kernel.

coninfo - print console devices and information
Usage:
coninfo
=>
The
coninfo command (short:
conin) displays information about the available
console I/O devices.
=> conin
List of available devices:
serial 80000003 SIO stdin stdout stderr
serial1 00000003 .IO
serial0 00000003 .IO
nc 80000003 SIO
=>
The output contains the device name, flags, and the current usage.
For example, the output
serial 80000003 SIO stdin stdout stderr
means that the
serial device is a system device
(flag
'S') which provides input (flag
'I') and output (flag
'O')
functionality and is currently assigned to the 3 standard I/O streams
stdin,
stdout and
stderr.
=> help flinfo
flinfo - print FLASH memory information
Usage:
flinfo
- print information for all FLASH memory banks
flinfo N
- print information for FLASH memory bank # N
=>
The command
flinfo (short:

can be used to get information about the available flash memory (see
Flash Memory Commands below).
=> fli
