contain either value 'down' or 'up', otherwise it will be empty.

Some Bluetooth controllers, like the BCM4345C5 of the Orange Pi 3,
ship with the controller default address.
Add a config option to fix it up so it can function properly.

Orange Pi 3 has 2 GiB of DRAM, that sometime get misdetected
as 4 GiB, due to false negative result from mctl_mem_matches()
when detecting number of column address bits. This leads to
u-boot detecting more address bits than there are and the
boot process hangs shortly after.
In mctl_mem_matches() we need to wait for each write to finish,
separately. Without this, the check is not reliable for some
unknown reason, probably having to do with unpredictable memory
access ordering.
Patch was made with help from André Przywara, who noticed that
my original idea about detection failing due to read-back from
cache without involving DRAM was false, because data cache is
still of at the time of the DRAM size autodetection.

This is useful for boot scripts to be able to decide whether to
boot or not and whether to notify the user of what is wrong.

Device tree is slightly different from Linux kernel one, because of
different ABI for display timings between u-boot and Linux.

- Enable LVDS pins (PD18-PD27)
- De-assert LVDS interface reset line
- Enable sunxi_lcd platform device for A83T
- Really disable all interrupts
- A83T does have only a simple clock gate for TCON0 clock
(no need to select source)
- Lifted some analog circuitry setup magic from the Linux driver

A83T SoC has PLL_DE at pll9. Change the name to make it less
confusing when we'll add DE2 support for A83T.

Shows a menu of items that can be controlled using touch panel.
This is useful for touch based devices like tablets to select
alternative boot options (multi-boot).

We don't have DM support for PMIC/GPIO/regulators, so this needs
to be handled via config options and some custom board initialization
code for now.
