With this change you can not access the env partition from linux therefore you can never use tools like fw_pritnenv/fw_setenv. Can you please change this to a reasonable configuration. I think current setups will require about 1 sector for bootstrap, 1 or 2 sectors for each env, about 4 to 6 sectors for u-boot, another bunch of sectors for linux and maybe some place to store a configuration blob (think of 'Falcon mode' or FDT).
