The iNet-tek iNet-1 PCB is a PCB found in various generic 10.1" 1024x600
A10 based tablets such as the Point of View Protab2 XXL and the
Cherry M1007.

This patch has been tested on both rev2 and rev5 of this board / these
tablets.

It comes with a rtl8188cus usb wifi connected to ehci1, focal ft5406ee8
touchscreen connected to i2c2 addr 0x38, bosch bma 250 accelerometer
connected to i2c1 addr 0x18 and the usual connectors: headphone,
mini hdmi, power-barrel, mini-usb and a micro-sd slot.

The inet9f-rev03 pcb is specially designed for gaming tablets, such as
the qware tb-g100 tablet.

These 7" tablets feature a dpad, firebuttons and 2 joysticks on the sides
of the screen.

Besides this they have the usual connectors: power-barrel, mini usb,
mini hdmi, headphone and micro-sd slot.

Cheap allwinner based devices in the q8 enclosure come in many variants,
all sharing the case and a number of other basic features.

They differ in the display, touchscreen, accelerometer and wifi chips
used.

This commit adds 2 dtsi files defining the shared features of all the
q8 tablets. sunxi-q8-common.dtsi defines features shared amongst all
q8 tablets, sun8i-q8-common.dtsi defines features shared amongst all
a23 / a33 based q8 tablets, but not with a13 q8 based tablets.

a13 based tablets use a different card-detect pin for the mmc, and
use uart1 instead of the r_uart for the serial console.

sun7i-a20.dtsi contains a cpufreq operating point at 0.9 volts. The minimum
CPU voltage for the Allwinner A20 SoC, however, is 1.0 volts. Thus, raise
the voltage for the lowest operating point to 1.0 volts in order to stay
within the SoC specifications. It is an undervolted setting that isn't
stable across all SoCs and boards out there.

When loading x86 64bit kernel above 4GiB with patched grub2, got kernel

the new buffer is at 0x46fe000000ULL, decompressor_gzip is using
0xffffffb901ffffff as out_len.  gunzip in lib/zlib_inflate/inflate.c cap
that len to 0x01ffffff and decompress fails later.

We could hit this problem with crashkernel booting that uses kexec loading
kernel above 4GiB.

We have decompress_* support:
    1. inbuf[]/outbuf[] for kernel preboot.
    2. inbuf[]/flush() for initramfs
    3. fill()/flush() for initrd.
This bug only affect kernel preboot path that use outbuf[].

Add __decompress and take real out_buf_len for gunzip instead of guessing
wrong buf size.

Current base address is wrong by 0x04 bytes for AHB bus device as shown
in dmesg:

	tegra-ahb 6000c004.ahb: incorrect AHB base address in DT data - enabling workaround

To correct old DTBs, commit ce7a10b0 ("ARM: 8334/1: amba: tegra-ahb:
detect and correct bogus base address") checks for the low bit of the
base address and removes theses 0x04 bytes at runtime.

This patch fixes the original DTS, so upstream version doesn't need the
workaround of the base address.

As both addresses are valid, this patch doesn't break compatibility.

Tested on tegra20-paz00 (aka ac100).
