Process Environment for MPC8265A (603e) ...


The following patch implements the memory protection for the PowerPC architecture. The patch was generated against the ecos repository from July 4th 2003.

Attached there is also a file BUILD.txt that describes the build environment and configuration we used. Note that there is a small error in the repository version of clock.cxx. Apart from that, everything builds without errors or warnings.

Note, that the patch also contains changes that do not directly belong to the memory protection, but were hard to separate.

These changes are: 
	(*) warnings about const/non-const issues, 
	(*) syntactical problems we had with the mempools and the roundup macro.

best regards,
