[U-Boot-Users] [PATCH 5/8] SPARC: Added AMBA PnP Information listing command for LEON3

Thu Mar 13 10:39:25 CET 2008
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 at 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.
