configs: update cubieboard2 defconfig This patch updates the Cubieboard2 board defconfig to use newer u-boot and linux versions, along with a few other improvements. The other improvements were mostly backported from the recent Orange Pi defconfig inclusion and are related to image generation. linux-sunxi.org was used as a reference for both linux and u-boot defconfig names. In detail: - Update linux to vanilla upstream -- currently 4.3.3 is the most up-to-date. Although it lacks some features present only in the linux-sunxi 3.4 branch, upstream support appears to be relatively mature and is already being deployed by default by distributions such as Arch Linux ARM. - Update u-boot to vanilla upstream 2015.10. According to linux-sunxi.org, upstream fully supports major functions (except NAND) since 2015.07. - Change image format to zImage and drop custom image generation script in favour of genimage, as pointed out by reviewers in the Orange Pi defconfig submission. This was tested in a Cubieboard2 board with boot from mmc and it boots fine to login prompt. This has not been tested in a Cubieboard (A10) as I don't own any; the version bumps probably apply to it although there are some differences (lack of VFPv4 support, Cortex-A8 instead of Cortex-A7), so I have kept the current Cubieboard defconfig and its scripts. This one has been only build-tested.

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.
