From a804b5ce2d84dca6f9e145003e588876adf2c71f Mon Sep 17 00:00:00 2001 From: Guilherme Maciel Ferreira Date: Sun, 1 Dec 2013 12:43:11 -0700 Subject: Add dumpimage, a tool to extract data from U-Boot images Given a multi-file image created through the mkimage's -d option: $ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \ multi.img Image Name: x86 Created: Thu Jul 25 10:29:13 2013 Image Type: Intel x86 Linux Multi-File Image (gzip compressed) Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB It is possible to perform the innverse operation -- extracting any file from the image -- by using the dumpimage's -i option: $ dumpimage -i multi.img -p 2 System.map Although it's feasible to retrieve "data files" from image through scripting, the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose is cumbersome and unreliable -- once you must keep track of file sizes inside the image. Furthermore, extracting data files using "dumpimage" tool is faster than through scripting.

In this mode, a single differential clock is supplied to the DIFF_SYSCLK_P/N inputs to the processor, which in turn is used to supply clocks to the sysclock, ddrclock and usbclock. So, both ddrclock and syclock are driven by same differential sysclock in single-source clocking mode whereas in normal clocking mode, generally separate DDRCLK and SYSCLK pins provides reference clock for sysclock and ddrclock DDR_REFCLK_SEL rcw bit is used to determine DDR clock source -If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in normal clocking mode by DDR_Reference clock -If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in single source clocking mode by DIFF_SYSCLK Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.
