This patch adds an U-Boot command, ambapp, which prints a summary of AMBA Bus Plug & Play information.

AMBA is a bus specified by ARM. AMBA with Plug and Play information is a Gaisler extension to that bus. See www.gaisler.com.

commit 8e2783598c9270a17140930c99b3eb76f892de51 Author: Daniel Hellstrom daniel@gaisler.com Date: Wed Mar 12 21:26:31 2008 +0100

SPARC/LEON3: Added AMBA Bus Plug&Play information print command (ambapp). It can print available cores (type: AHB Master, AHB Slave, APB Slave), their address ranges, IRQ number and version.
