CONFIG_ENV_SIZE = CONFIG_ENV_SECT_SIZE = 128kB but CONFIG_SYS_STACK_SIZE is only 32kB resulting in saveenv causing a stack overflow and crashing U-Boot. Resolve by reducing CONFIG_ENV_SIZE to 4kB
Also fix up CONFIG_SYS_MALLOC_LEN to correctly use environment sector size and add some comments to the memory organisation configuration
