On recent u-boots, the watchdog is turned on / left enabled. The Beaglebone Black rev. C ships with such a u-boot internally so any application booting from it must disable the watchdog. Therefore this change is needed to boot an RTEMS app out-of-the-box on a BBB Rev C - otherwise the user button must be held during boot (to bypass the stock uboot) or the internal uboot must be updated. To allow for a better out-of-the-box experience, we just turn off the watchdog.
This is the README file for libcpu. This directory contains reusable libraries which are CPU dependent but not target board dependent. For example, the PowerPC has an on CPU decrementer register which may be used by all PowerPC BSP's for the Clock and Timer Drivers. Other examples include the caching support for the m68k CPU models and MIPS CPU model exception vectoring routines. This level of support will make it easier for others developing embedded applications on a given CPU.
