ad8783cb1c boston: Introduce support for the MIPS Boston development board
This patch introduces support for building U-Boot to run on the MIPS
Boston development board. This is a board built around an FPGA & an
Intel EG20T Platform Controller Hub, used largely as part of the
development of new CPUs and their software support. It is essentially
the successor to the older MIPS Malta board.

TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a
16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can
be used as an input or output without the use of a data-direction
control signal. The I/Os should be high before being used as inputs.
Read the device documentation for more details[1].

This driver is based on pcf857x driver available in Linux v4.7 kernel.
It supports basic reading and writing of gpio pins.

b47ea79219 rockchip: add option to change method of loading u-boot
If we would like to boot from SD card, we have to implement mmc driver
in SPL stage, and get a slightly large SPL binary. Rockchip SoC's
bootrom code has the ability to load spl and u-boot, then boot.

If CONFIG_ROCKCHIP_SPL_BACK_TO_BROM is enabled, the spl will return to
bootrom in board_init_f(), then bootrom loads u-boot binary.

Loading sequence after rework:
bootrom ==> spl ==> bootrom ==> u-boot

6f4e7d3c75 spl: Lightweight UBI and UBI fastmap support
Booting a payload out of NAND FLASH from the SPL is a crux today, as
it requires hard partioned FLASH. Not a brilliant idea with the
reliability of todays NAND FLASH chips.

The upstream UBI + UBI fastmap implementation which is about to
brought to u-boot is too heavy weight for SPLs as it provides way more
functionality than needed for a SPL and does not even fit into the
restricted SPL areas which are loaded from the SoC boot ROM.

So this provides a fast and lightweight implementation of UBI scanning
and UBI fastmap attach. The scan and logical to physical block mapping
code is developed from scratch, while the fastmap implementation is
lifted from the linux kernel source and stripped down to fit the SPL
needs.

The text foot print on the board which I used for development is:

6854	0	0	6854	1abd
drivers/mtd/ubispl/built-in.o

Attaching a NAND chip with 4096 physical eraseblocks (4 blocks are
reserved for the SPL) takes:

In full scan mode:      1172ms
In fastmap mode:          95ms

The code requires quite some storage. The largest and unknown part of
it is the number of fastmap blocks to read. Therefor the data
structure is not put into the BSS. The code requires a pointer to free
memory handed in which is initialized by the UBI attach code itself.

See doc/README.ubispl for further information on how to use it.

This shares the ubi-media.h and crc32 implementation of drivers/mtd/ubi
There is no way to share the fastmap code, as UBISPL only utilizes the
slightly modified functions ubi_attach_fastmap() and ubi_scan_fastmap()
from the original kernel ubi fastmap implementation.

2fbb8462b0 autoboot: remove CONFIG_ZERO_BOOTDELAY_CHECK
As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2
means the autoboot with no delay, with no abort check even if
CONFIG_ZERO_BOOTDELAY_CHECK is defined.

To sum up, the autoboot behaves as follows:

 [1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y
    autoboot with no delay, but you can abort it by key input

 [2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
    autoboot with no delay, with no check for abort

 [3] CONFIG_BOOTDELAY=-1
    disable autoboot

 [4] CONFIG_BOOTDELAY=-2
    autoboot with no delay, with no check for abort

As you notice, [2] and [4] come to the same result, which means we
do not need CONFIG_ZERO_BOOTDELAY_CHECK.  We can control all the
cases only by CONFIG_BOOTDELAY, like this:

 [1] CONFIG_BOOTDELAY=0
    autoboot with no delay, but you can abort it by key input

 [2] CONFIG_BOOTDELAY=-1
    disable autoboot

 [3] CONFIG_BOOTDELAY=-2
    autoboot with no delay, with no check for abort

This commit converts the logic as follow:
  CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
    --> CONFIG_BOOTDELAY=-2

9f823615af Kconfig: Add a new DISTRO_DEFAULTS Kconfig option
DISTRO_DEFAULTS is intended to mirror / replace
include/config_distro_defaults.h.

The intend is for boards which include this file to select this from
their Kconfig files and when moving setting to Kconfig which are #define-ed
in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that
boards which have selected DISTRO_DEFAULTS will keep the same configuration
as before without needing any defconfig file changes.

The initial list of selected things matches all settings recently removed
from config_distro_defaults.h because they have been converted to Kconfig,
with the exception of CMD_ELF and CMD_NET, which have a default of y, if
the default of these ever changes they should be selected by DISTRO_DEFAULTS
too.

For testing and example purposes this commit also converts ARCH_SUNXI
to use DISTRO_DEFAULT instead of selecting everything it needs itself.

3e584b94d2 doc, spl, am335x: update am335x-network
on the shc board we see when booting in net boot mode,
that the ROM bootloader sends "AM335x ROM" as
vendor-class-identifier. U-Boots doc says "DM814x ROM".

So, add the info to the doc, that there is also
"AM335x ROM" possible.
