Alexey Brodkin 0ce3963a62 cubieboard2: Accommodate U-Boot environment on SD-card ... According to current "include/configs/sunxi-common.h" U-Boot environment is stored on SD-card with offset 544 kB and its size is limited as 128 kB. Given memory layout of sunxi boards: 1. SPL 2. U-Boot 3. U-Boot environment 4. Partitions (see http://linux-sunxi.org/Bootable_SD_card#SD_Card_Layout for details) we need to make sure the first real partition starts at least with 544+128 kB offset. Adding a small safety gap let's put the first partition with offset 1MB from the beginning of SD-card. Otherwise current setup gets broken as soon as one saves U-Boot environment with "saveenv" which basically overwrites FAT partition with zImage and board no longer boots into Linux kernel.
