serial: Add serial driver for Intel MID
Add a specific serial driver for Intel MID platforms.
It has special fractional divider which can be programmed via UART_PS,
UART_MUL, and UART_DIV registers.
The UART clock is calculated as
UART clock = XTAL * UART_MUL / UART_DIV
The baudrate is calculated as
baud rate = UART clock / UART_PS / DLAB
Initialize fractional divider correctly for Intel Edison platform.
For backward compatibility we have to set initial DLAB value to 16
and speed to 115200 baud, where initial frequency is 29491200Hz, and
XTAL frequency is 38.4MHz.

ARMv8: add GOT sections to the list of sections copied
Recent Linux distributions (e.g. Debian 9) include cross-compilers for
AArch64, but only for the aarch64-linux-gnu triplet only. It can thus
be expected that users will attempt to use the system cross-compiler
(instead of an aarch64-elf variant) to compile U-Boot for their ARMv8
target systems.
One key differences between an aarch64-linux-gnu and an aarch64-elf
compiler are the default settings regarding position-independent: with
the aarch64-linux-gnu compiler, the default will create and use the
global offset table.
This change-set adjusts the list of sections copied on ARMv8 to include
the GOT sections. With this added, the list matches the previous setup
for AArch32 closely.
Note that this is not an 'academic' issue, but was in fact encountered

early failure of the SPL stage during FDT setup.

mtd: sunxi: Change U-Boot offset
The default U-Boot offset for the Allwinner SoCs was set to 32kB.
This was probably to try to maintain some compatibility with the current
image that we build for the MMC where the U-Boot binary is also located at
a 32kB offset.
However, this causes a number of issues. The first one is that it prevents
us from using a backup SPL entirely, which is troublesome in case where the
first would be corrupt (especially on MLC which have a higher number of
bitflips).
We also cannot use the original MMC image on the NAND, because we need to
prepare the SPL image to include the ECCs and randomizer settings, which
reduces the interest of setting it at that particular offset.
It also prevents us from upgrading and flashing the U-Boot and SPLs
independantly, since it's very likely that it will fall in the same erase
block.
Since that default wasn't used by any board, change it for 8MB, which will
be in an erase block of its own, all the erase blocks being multiple of
two. The highest erase block size we encountered is 4MB, which means that
in this particular setup, the first and second erase blocks will be for the
SPL and its backup, and the third for U-Boot.

tools: sunxi: Add spl image builder
This program generates raw SPL images that can be flashed on the NAND with
the ECC and randomizer properly set up.
This has been copied (and tweaked to find the right headers) from the
sunxi-tools (https://github.com/linux-sunxi/sunxi-tools) upstream
repository, commit 1c3a6ca5.

nand: sunxi: Fix modulo by zero error
When trying to autodetect the ECC and randomization configurations, the
driver starts with a randomization disabled and no seeds.
In this case, the number of seeds is obviously 0, and the randomize boolean
is set to false.
However, the logic that retrieves the seed for a given page offset will
blindly use the number of seeds, without testing if the randomization is
enabled, basically doing a modulo by 0.
As it turns out, the libgcc in the common toolchain returns 0 here, which
was our expected value in such a case, and why we would not detect it.
However, U-Boot's libgcc will for some reason return from the function
instead, resulting in an error to load the U-Boot binary in the SPL.

Remove various unused interrupt related code
With d53ecad92f06 some unused interrupt related code was removed.
However all of these options are currently unused. Rather than migrate
some of these options to Kconfig we just remove the code in question.
The only related code changes here are that in some cases we use
CONFIG_STACKSIZE in non-IRQ related context. In these cases we rename
and move the value local to the code in question.

Makefile: Provide an option to select SPL or TPL
At present we have SPL_ which can be used in Makefiles to select between
normal and SPL CONFIGs like this:
obj-$(CONFIG_$(SPL_)DM) += core/
When TPL is being built, SPL_ has the value 'SPL' which is generally a
good idea since they tend to follow each other. But in extreme situations
we may want to distinugish between SPL and TPL. For example we may not
want to enable CONFIG_DM with TPL.
Add a new SPL_TPL_ variable which is set to either empty (for U-Boot
proper), 'SPL' or 'TPL'. This may prove useful with TPL-specific options.
