This is indeed a bug, then. To give you an example - in
"include/configs/TQM5200.h" we have:
#define CONFIG_ENV_SIZE 0x4000 /* 16 k - keep small for fast
booting */
...
#define CONFIG_ENV_SECT_SIZE 0x40000
This works fine - CRC computation covers only the 16 k as set in
CONFIG_ENV_SIZE.
It seems you really have a bug there, which should be fixed.
Best regards,
Wolfgang Denk
