With recent toolchains, the environment sectors were no longer aligned to sector boundaries. The reason was a combination of two bugs: 1) common/environment.c assumed that CONFIG_TQM8xxL would be defined for all TQM8xxL and TQM8xxM boards. But "include/common.h", where this gets defined, is not included here (and cannot be included without causing lots of problems). Added a new #define CFG_USE_PPCENV for all boards which really want to put the environment is a ".ppcenv" section. 2) The linker scripts just include environment.o, silently assuming that the objects in that file are really in the order in which they are coded in the C file, i. e. "environment" first, then "redundand_environment", and "env_size" last. However, current toolchains (GCC-4.x) reorder the objects, causing the environment data not to start on a flash sector boundary: Instead of: we got: 40008000 T environment 40008000 T env_size 4000c000 T redundand_environment 40008004 T redundand_environment 40010000 T env_size 4000c004 T environment Note: this patch fixes just the first part, and cures the alignment problem by making sure that "env_size" gets placed correctly. However, we still have a potential issue because primary and redundant environment sectors are actually swapped, i. e. we have now: 40008000 T redundand_environment 4000c000 T environment 40010000 T env_size This shall be fixed in the next version.
