RK3399 is a SoC from Rockchip with dual-core Cortex-A72
and quad-core Cortex-A53 CPU. It supports two USB3.0
type-C ports and two USB2.0 EHCI ports. Other interfaces
are very much like RK3288, the DRAM are 32bit width address
and support address from 0 to 4GB-128MB range.

Some SoCs have a single clock device. Provide a way to find it given its

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.

A couple of commits have modified the am33xx/am437x ddr2/ddr3
initialization path to fix certain issues, but have had the side effect
of causing L3 noc errors during initialization. The two commits are:

69b918 "am33xx,ddr3: fix ddr3 sdram configuration"
fc46ba "arm: am437x: Enable hardware leveling for EMIF"

The EMIF_REG_INITREF_DIS_MASK bit still needs to be set for all
platforms. This delays initialization and refresh until a later stage.
The 500us timer can be programmed for platforms that require it
and for platforms that don't require it. It is currently hardcoded
for 400MHz systems. For systems with a higher memory frequency
this needs to be a larger value, and for systems with a lower
memory frequency this can be a lower value. This can be
considered a separate issue and corrected in a later commit.

On file system backends, there are no relative paths, so we should always

In certain circumstances it comes in handy to be able to boot into a second
U-Boot. But as of now it is not possible to boot a U-Boot binary that is inside
a FIT image, which is problematic for projects that e.g. need to guarantee a
unbroken chain of trust from SOC all the way into the OS, since the FIT signing
mechanism cannot be used.

This patch adds the capability to load such FIT images.

An example .its snippet (utilizing signature verification) might look
like the following:

images {
	firmware@1 {
		description = "2nd stage U-Boot image";
		data = /incbin/("u-boot-dtb.img.gz");
		type = "firmware";
		arch = "arm";
		os = "u-boot";
		compression = "gzip";
		load = <0x8FFFC0>;
		entry = <0x900000>;
		signature@1 {
			algo = "sha256,rsa4096";
			key-name-hint = "key";
		};
	};

A feasible way to communicate certain errors for devices that have no
other way of signalling besides LEDs is to flash these LEDs. For errors
in U-Boot, a script that utilizes the led and sleep commands would be a
practicable way, but currently the sleep command can only delay for an
integral amount of seconds, which is too slow to create an easily
noticeable pattern for flashing LEDs.

Therefore, this patch adds support for fractions (down to .001 seconds)
to the sleep command.

The parsing is kept minimal, simplistic and as robust as possible: After
converting the passed string using simple_strtoul and multiplying it
with 1000, we search for the first dot, convert the three characters
after that into a number (if they are not numbers, we ignore the
fractional part and just use the delay we got from simple_strtoul), and
add this number to the delay.

nand_do_write_ops() determines if it is writing a partial page with the
formula:
	part_pagewr = (column || writelen < (mtd->writesize - 1))

When 'writelen' is exactly 1 byte less than the NAND page size the formula
equates to zero, so the code doesn't process it as a partial write, although
it should.
As a consequence the function remains in the while(1) loop with 'writelen'
becoming 0xffffffff and iterating until the watchdog timeout triggers.

To reproduce the issue on a NAND with 2K page (0x800):
	=> nand erase.part <partition>
	=> nand write $loadaddr <partition> 7ff
