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.

[Peter: extend description, add padding to u-boot partition instead]

53c1dadbcc 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.

2257e36a57 cubieboard: mkcubiecard: use the right command for checking user privilege
On some shell environments the EUID variable, which checks the
user id, is not defined. Use `id -u` instead.

This patch mutes the following error:

./board/cubietech/cubieboard/mkcubiecard.sh: 31: [: -ne: unexpected operator
