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.
