First set of u-boot-atmel features for 2020.04 cycle
This feature set is a patch series from Tudor Ambarus which includes
parsing of the spi flash SFDP parser for SST flashes, and using those
tables to retrieve unique saved per device MAC address. This is then
used as base mac address on the SAMA5D2 Wireless SOM EK board.
The ECC registers in the SDRAM HMC Adapter should always

When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.
This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.
The patch is based on the commit
5e966ccc3c
by Sebastien Colleur, which has been heavily reworked due to U-Boot changes
in the past.

The Rockchip SPI controller's length register only supports 16-bits,
yielding a maximum length of 64KiB (the CTRLR1 register holds "length -
1"). Trying to transfer more than that (e.g., with a large SPI flash
read) will cause the driver to hang.
Now, it seems that while theoretically we should be able to program
CTRLR1 with 0xffff, and get a 64KiB transfer, but that also seems to
cause the core to choke, so stick with a maximum of 64K - 1 bytes --
i.e., 0xffff.
Note, that the size is further divided into 'minus 1' while writing
into CTRLR1.
This change fixed two different read issues,
1. sf read failure when with > 0x10000
2. Boot from SPI flash failed during spi_flash_read call in
common/spl/spl_spi.c

Use debug() instead of printf() to reduce code size and change a bool
return value to the use the 'bool' type. Also drop the global data
declaration since it not actually used. Finally, set the log category.

Use dev_get_driver_data() to obtain the device type. It has the same

Reduce the size of the probe function but putting this code into its own
function.
Also remove the assumption that the PCH is always a parent of the SPI
controller, as this is not the case APL platforms. Use driver model to
find the PCH instead.

It is annoying to have some of the init code in a different part of the
file. Move ich_init_controller() to just above probe() to keep things
together.

We don't normally need this on x86 unless the size of SPI flash devices is
larger than 16MB. This can be enabled by particular SoCs as needed, since
it adds to code size.
Drop the default enabling of this option on x86.

These drivers are not needed on all platforms. While they are small, it
is useful in TPL to drop then. Add Kconfig control to allow this.

Update this uclass to support the needs of the Apollo Lake ITSS. It

Move the uclass into a separate directory so that sandbox can use it too.
Add a new Kconfig to control it and enable this on x86.

Add a sandbox driver and PCI-device emulator for p2sb. Also add a test

The Primary-to-Sideband bus (P2SB) is used to access various peripherals
through memory-mapped I/O in a large chunk of PCI space. The space is
segmented into different channels and peripherals are accessed by
device-specific means within those channels. Devices should be added in
the device tree as subnodes of the p2sb.
This adds a uclass and enables it for sandbox.

Most of the timer-calibration methods are not needed on recent Intel CPUs
and just increase code size. Add an option to use the known-good way to
get the clock frequency in TPL. Size reduction is about 700 bytes.
Note that version 1 of this commit caused bootstage to crash since the CPU
was not identified. This is corrected by changes previously applied to
make sure that the CPU is identified before spl_init() is called, such as

On x86 platforms the timer is reset to 0 when the SoC is reset. Having
this as the timer base is useful since it provides an indication of how
long it takes before U-Boot is running.
When U-Boot sets the timer base to something else, time is lost and we
no-longer have an accurate account of the time since reset. This
particularly affects bootstage.
Change the default to not read the timer base, leaving it at 0. Add an
option for when U-Boot is the secondary bootloader.

Allow this driver to set up an IO address in SPL using an 'early-regs'
property. This allows SPL to use the I2C driver without having to enable
the full PCI stack.
Also split out ofdata_to_platdata in designware driver since this is more
correct, and more convenient for the new logic.
