lcd_dt_simplefb_configure_node is also a good candidate to be converted

lcd_dt_simplefb_configure_node does not honor #address-cells and #size-cells,

This adds a fixed mode hdmi driver for the sunxi platform. The fixed
mode is a relatively safe 1024x768, more complete EDID handling is
currently not provided. Only HDMI is supported today.
This code is enabled when HPD detects an attached monitor.
Current config is such that 8MB is shaved off at the top of the RAM.
This avoids several memory handling issues, most significant is the fact
that on linux on ARM you are not allowed to remap known RAM as IO. A
clued in display driver will be able to recycle this reserved RAM in
future though.
cfbconsole was chosen as it provides the most important functionality: a
working u-boot console, allowing for the debugging of certain issues
without the need for a UART.

As LS1 is a little-endian processor, getting the version ID by

U-Boot has never cared about the type when we get max/min of two

macros synced with the kernel introducing type checks.
Many of references of those macros must be fixed to suppress warnings.
We have two options:
- Use min, max, min3, max3 only when the arguments have the same type
(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
argument

The simple malloc() implementation is used when memory is tight. It provides
a simple buffer with an incrementing pointer.
At present the implementation is inside dlmalloc. Move it into its own file
so that it is easier to find.
Rather than using relocation as a signal that the full malloc() is
available, add a special GD_FLG_FULL_MALLOC_INIT flag. This signals that the
simple malloc() should no longer be used.
In some cases, such as SPL, even the code space used by the full malloc() is
wasteful. Add a CONFIG_SYS_MALLOC_SIMPLE option to provide only the simple
malloc. In this case the full malloc is not available at all. It saves about
1KB of code space and about 0.5KB of data on Thumb 2.

Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in
the board directory and the SDRAM SPD information in the device tree. This
also needs the Intel Management Engine (me.bin) to work. Binary blobs
everywhere: so far we have MRC, ME and microcode.
SDRAM init works by setting up various parameters and calling the MRC. This
in turn does some sort of magic to work out how much memory there is and
the timing parameters to use. It also sets up the DRAM controllers. When
the MRC returns, we use the information it provides to map out the
available memory in U-Boot.
U-Boot normally moves itself to the top of RAM. On x86 the RAM is not
generally contiguous, and anyway some RAM may be above 4GB which doesn't
work in 32-bit mode. So we relocate to the top of the largest block of
RAM we can find below 4GB. Memory above 4GB is accessible with special
functions (see physmem).
It would be possible to build U-Boot in 64-bit mode but this wouldn't
necessarily provide any more memory, since the largest block is often below
4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large
ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit
kernels directly so this does not pose a limitation in that area. Also there
are probably parts of U-Boot that will not work correctly in 64-bit mode.
The MRC is one.
There is some work remaining in this area. Since memory init is very slow
(over 500ms) it is possible to save the parameters in SPI flash to speed it
up next time. Suspend/resume support is not fully implemented, or at least
it is not efficient.
With this patch, link boots to a prompt.
