0c1413f6d7 test: bootdev: Do not require USB to compile test
This test will block compilation of the entire test suite
on platforms without USB support. Make the extern
"usb_started" conditional on USB host or gadget and
define a dummy flag if neither is enabled.

Fix shell error:

It seems for os_x_before for some reason DARWIN_MAJOR_VERSION and
DARWIN_MINOR_VERSION are empty. To fix this set DARWIN_MAJOR_VERSION

from the fdt after receiving the same from the EFI memory map fails due

007ae5d108 lmb: Default to not-LMB_USE_MAX_REGIONS
The LMB code allows for picking a hard limit on the number of regions it
can know of, or to dynamically allocate these regions. The reason for
this choice is to allow for the compiler to perform a size optimization
in the common case. This optimization however, is very small, ranging
from 196 bytes to 15 bytes saved, or in some cases, being larger. Now
that we also have more regions covered by LMB (in order to protect
various parts of our self at run time), the default of 8 is also much
easier to hit and leads to non-obvious error messages (which imply that
an area is protected, not that we're out of areas to add to the list).

Switch to the dynamic use as the default.

Marek: - Fix missing ~ in GENMASK(a, b), use clrsetbits_le32 instead
       - Do not modify r8a77970-cpg-mssr.c much, drop enum r8a77970_clk_types
         which is now part of common clock types in rcar-gen3-cpg.h instead

4dbbc3f373 clk: renesas: Switch to new SD clock handling
The old SD handling code was huge and could not handle all the details
which showed up on R-Car Gen3 SoCs meanwhile. It is time to switch to
another design. Have SDnH a separate clock, use the existing divider
clocks and move the errata handling from the clock driver to the SDHI
driver where it belongs.

Based on Linux series by Wolfram Sang, commit bb6d3fa98a41 ("clk:
renesas: rcar-gen3: Switch to new SD clock handling") and commit

Marek: - Add rcar_clk_* prefix to all functions
       - Fix missing ~ in GENMASK(a, b), use clrsetbits_le32 instead
       - Use DIV_ROUND_CLOSEST, else if parent clock = 199999992 and
         rate = 200000000, the divider would be 0 and table lookup
	 would fail.
       - Turn rcar_clk_get_table_val into signed integer, so it can
         return 0 as a valid value and negative values as errors.
       - Make the code operate on correct clock and add comment
         which explains the reasoning behind it.
       - Rebase on changes to
         clk: renesas: Introduce and use rcar_clk_get_rate64_div_table function

c287c184ae clk: renesas: Handle E3/D3 RPCSRC clock
The RPCSRC clock divider on R-Car D3 is very similar to the one on R-Car
E3, but uses a different pre-divider for the PLL0 parent.  Add a new
macro to describe it, reusing the existing clock type for R-Car E3.

As both E3/D3 RPCSRC clock divider are different from the rest of R-Car
Gen3, keep the original implementation from Linux.

a1ec0bbc28 clk: renesas: Introduce and use rcar_clk_get_rate64_div_table function
Introduce new helper function to handle clock type that uses
clk_div_table struct. Based vaguely on Linux code. Make use
of clk_div_table in RPC clocks handling.

The E3/D3 RPCSRC need to be handled differently and will be addressed in
subsequence patch.

Marek: - Squash patches to avoid adding unused code:
         clk: renesas: Make use of clk_div_table in RPC clocks handling
         clk: renesas: Introduce rcar_clk_get_rate64_div_table function
       - Move the new code to the beginning of clk-rcar-gen3 to avoid
         tables mixed with code
       - Use rcar_ prefix for get_table_div function
       - Get rid of custom macros, use GENMASK. Use custom field_get
         implementation as the generic FIELD_GET does not support
	 constant mask and u32_get_bits requires higher optimization level
       - Pass in the register bit mask instead of width/shift combination
       - Turn rcar_clk_get_rate64_div_table into s64, as it can return -EINVAL
