[U-Boot] [PATCH 1/2] sunxi: A23: Fix some revisions needing a different magic sram poke

[Hans de Goede]

I've had this one a23 tablet which would not boot and I've finally
figured out what the problem is by looking at the released boot0 code,
it seems the magic sram controller poke which we need to do in s_init()
depends on the revision of the a23.

Specifically this change is needed to get the A23 SoC I have with the
following serial to boot: "E6071AB 26Y7".

[U-Boot] [PATCH 2/2] sunxi: Add defconfig and dts for colorfly e708 q1 tablet

[Hans de Goede]

The colorfly e708 q1 is a 7" tablet which is clearly marked as colorfly
e708 q1 on the back. It features a 9:16 800x1280 IPS LCD, A31s SoC,
1GB RAM, 8G NAND, ilitek 2139qt004 touchscreen on i2c-1 addr 0x41,
stk8313 accelerometer on i2c-2 addr 0x22 and a rtl8188etv wifi chip.

The added dts is identical to the dts submitted to the upstream kernel,
note this commit also syncs axp22x.dtsi and sun6i-a31.dtsi with the
upstream kernel as the added dts depends on these.
