On the A31s the RTC is by default secured. Thus when u-boot
loads the kernel in non-secure world, the RTC is unavailable. The
SoC has a TrustZone Protection Controller, which can be used to
enable non-secure access to the RTC.
On the A31 the TZPC doesn't seem to do anything, i.e. changes to
its register contents do not affect access to the RTC.

We only ever use syndrome mode for the partitions which contain the SPL,
as that is required for the BROM to be able to read the SPL.
Instead of using some arbritray limit for deciding whether or not to
use syndrome, be smart and check if u-boot-dtb.bin is directly behind
the SPL, if it is not then it is on its own partition and we should not
use syndrome.
Note the reason why we only use syndrome mode for the SPL is because it
comeswith weaker randomization, introducing a risk for more bit errors,
so we want to avoid it when possible.

We eventually want to add full nand support, since it makes no sense

The BROM does not care / use bad page markings, instead it deals with
any bad pages in the first erase-block by simply trying to load "boot0"
from the next erase-block.

partition is bad (tested by erasing the main boot partition).

Auto detect the nand configuration parameters, like the BROM does.
This allows us to get rid of various Kconfig settings, and is
necessary to support generic boards like the mk802 which have seen
many production runs with different nands.
The full blown u-boot/kernel nand driver uses the nand id to determine
this info, for the SPL we do as the BROM does and simply try a few
standard configs.
Note the table only contains configs which are known to actually be used,
rather then all the configs the BROM tries. This means that it may need
to be updated in the future as we add support for nand on more boards.

nand_spl_load_image() always gets called with either CONFIG_SYS_TEXT_BASE

This saves CONFIG_NAND_SUNXI_SPL_ECC_PAGE_SIZE (typically 1k) in

With the unified / cleaned up default display output selection changes,
which were done as part of adding composite video out support, our
example LCD_MODE line in the A13-OLinuxIno defconfigs causes the display
code to setup a LCD console by default, rather then a VGA console.
Given that the LCD console is only useful for people who have hooked up
the exact lcd-panel from the config, while most people will not have any
lcd panel connected to these boards, this is not a good default.
Dropping the LCD_MODE line which was intended as an example fixes this,
