When calling efi_dp_find_obj(), we usually want to find the *exact* match
of an object for a given device path. However, I ran into a nasty corner case
where I had the following objects with paths available:
because that path is a full substring of the path we were searching for.
So this patch adapts the device path search logic to always look for exact
matches first. The way we distinguish between those cases is by looking at
whether our caller actually deals with remainders.
As a side effect, the code as is from all I can tell now never does a
substring match anymore, because it always gets called with rem=NULL, so
we always only do exact matches now.

efi_loader: helloworld.c: Explicitly use .rodata for loaded_image_guid
Commit bbf75dd9345d0b ("efi_loader: output load options in helloworld")
introduced a const variable in efi_main() called loaded_image_guid which
got populated from a constant struct.
While you would usually expect a compiler to realize that this variable
should really just be a global pointer to .rodata, gcc disagrees and instead
puts it on the stack. Unfortunately in some implementations of gcc it does
so my calling memcpy() which we do not implement in our hello world
environment.
So let's explicitly move it to a global variable which in turn puts it in
.rodata reliably and gets rid of the memcpy().

binman: Support accessing binman tables at run time
Binman construct images consisting of multiple binary files. These files
sometimes need to know (at run timme) where their peers are located. For
example, SPL may want to know where U-Boot is located in the image, so
that it can jump to U-Boot correctly on boot.
In general the positions where the binaries end up after binman has
finished packing them cannot be known at compile time. One reason for
this is that binman does not know the size of the binaries until
everything is compiled, linked and converted to binaries with objcopy.
To make this work, we add a feature to binman which checks each binary
for symbol names starting with '_binman'. These are then decoded to figure
out which entry and property they refer to. Then binman writes the value
of this symbol into the appropriate binary. With this, the symbol will
have the correct value at run time.
Macros are used to make this easier to use. As an example, this declares
a symbol that will access the 'u-boot-spl' entry to find the 'pos' value
(i.e. the position of SPL in the image):
This converts to a symbol called '_binman_u_boot_spl_prop_pos' in any
binary that includes it. Binman then updates the value in that binary,
ensuring that it can be accessed at runtime with:

ARC: clk: introduce HSDK CGU clock driver
Synopsys HSDK clock controller generates and supplies clocks to various

Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the
dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device
tree sources.
dcache_exists, icache_exists, slc_exists and ioc_exists global
variables in "arch/arc/lib/cache.c" remain uninitialized if
SoC doesn't have corresponding HW.
This happens because we use the next constructions for their
definition and initialization:

int ioc_exists __section(".data");
if (/* condition */)
ioc_exists = 1;

That's quite a non-trivial issue as one may think of it.
The point is we intentionally put those variables in ".data" section
so they might survive relocation (remember we initilaize them very early
before relocation and continue to use after reloaction). While being
non-initialized and not explicitly put in .data section they would end-up
in ".bss" section which by definition is filled with zeroes.
But since we place those variables in .data section we need to care
about their proper initialization ourselves.
