From 2d6441d17e291e3779c117aaf048e74a26834bc0 Mon Sep 17 00:00:00 2001 From: Scott Rifenbark Date: Thu, 11 Nov 2010 10:23:10 -0800 Subject: BSP Guide and BSP Chapter: Sync'ed these two files After moving BSP Guide into its own folder for documentation I discovered a consequence of that. There are two separate bsp.xml files now: one in the poky-ref-manual folder and one in the bsp folder. I had done some good cleanup work in the version in the poky-ref-manual folder. This commit reflects a 'meld' operation where I re-sync'ed the bsp.xml file in the bsp-guide folder to be the same (almost) as the one in the poky-ref-manual folder. There is still one slight difference between the two files due to one's context as a stand-alone manual and the other as a section in a larger book.
