1*4882a593SmuzhiyunThis file contains status information for the port of U-Boot to the 2*4882a593SmuzhiyunMotorola mpc74xx series of CPUs. 3*4882a593Smuzhiyun 4*4882a593SmuzhiyunAuthor: Josh Huber <huber@mclx.com> 5*4882a593Smuzhiyun Mission Critical Linux, Inc. 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunCurrently the support for these CPUs is pretty minimal, but enough to 8*4882a593Smuzhiyunget things going. (much like the support for the Galileo Eval Board) 9*4882a593Smuzhiyun 10*4882a593SmuzhiyunThere is a framework in place to enable the L2 cache, and to program 11*4882a593Smuzhiyunthe BATs. Currently, there are still problems with the code which 12*4882a593Smuzhiyunsets up the L2 cache, so it's not enabled. (IMHO, it shouldn't be 13*4882a593Smuzhiyunanyway). Additionally, there is support for enabling the MMU, which 14*4882a593Smuzhiyunwe also don't do. The BATs are programmed just for the benefit of 15*4882a593Smuzhiyunjumping into Linux in a sane configuration. 16*4882a593Smuzhiyun 17*4882a593SmuzhiyunMost of the code was based on other cpus supported by U-Boot. 18*4882a593Smuzhiyun 19*4882a593SmuzhiyunIf you find any errors in the CPU setup code, please send us a note. 20*4882a593Smuzhiyun 21*4882a593SmuzhiyunThanks, 22*4882a593SmuzhiyunJosh 23
