currently pawing my way through the mechanics of u-boot environment,
and noticed that a small number of boards support:
$ grep -r PPCENV *
common/env_embedded.c:#if defined(CONFIG_SYS_USE_PPCENV) && \
common/env_embedded.c:# define __PPCENV__ __attribute__
((section(".ppcenv")))
common/env_embedded.c:# define __PPCENV__ /*XXX DO_NOT_DEL_THIS_COMMENT*/
common/env_embedded.c:# define __PPCENV__ __attribute__
((section(".text")))
common/env_embedded.c:env_t redundand_environment __PPCENV__ = {
include/configs/TQM823M.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM855L.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM866M.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM850L.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM860M.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM850M.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM862M.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM862L.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/inka4x0.h:#define CONFIG_SYS_USE_PPCENV /*
Environment embedded in sect .ppcenv */
include/configs/TQM855M.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM860L.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/configs/TQM823L.h:#define CONFIG_SYS_USE_PPCENV
/* Environment embedded in sect .ppcenv */
include/env_default.h:env_t environment __PPCENV__ = {
$
what is the rationale for that small selection of boards to put
their environment in a separate section? if i keep reading, i'm sure
it will become obvious.
