60c08dd771 arc: Remove common.h usage
We can remove common.h from most cases of the code here, and only a few
places need an additional header instead.

35b65dd8ef reset: Remove addr parameter from reset_cpu()
Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to.  This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value.  Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.

Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g.  COLD vs WARM resets).  As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).

To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely.  Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

This transformation was done with the following coccinelle patch:

    @@
    expression argvalue;
    @@
    - reset_cpu(argvalue)
    + reset_cpu()

    @@
    identifier argname;
    type argtype;
    @@
    - reset_cpu(argtype argname)
    + reset_cpu(void)
    { ... }

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

c77bbc2215 ARC: rework setting of ARC CPU specific compiler options
It's a very rare if at all existing occasion when ARC CPU template
is used as is w/o any changes - in the end it's a beauty and competitive
advantage of ARC cores to be tailored for a particular use-case - and
so it doesn't make a lot of sense to offer template-based "-mcpu" selection.
Given for each and every platform we end-up adding quite a few more flags
it's logical to move "-mcpu" selection to platform's definition as well
which we exactly do here.

3f6b4ea225 arc: emsdp: docs: Prefer Degilent over Opella-XD
Back in the day on early board samples built-in Digilent JTAG probe
was not functional so we used externally attached Ashling Opella-XD
probe. But now with production units everything works as expected and
so we anybody may enjoy readily avaialble built-in JTAG probe so
we specify Digilent oprion on MDB's command line example.

968b98bc27 arc: emsdp: Add more platform-specific compiler options
Even though EM SDP is FPGA-based board and different FPGA
images (known as .bit-files) are awailable for the board still
there's a common subset of options we may rely on for all configs.

These are:
 * Normalizer
 * Swap instructions
 * Simple multiplier
 * Barrel-shifter
 * Floating-point unit
 * Shorter instructions (code density)

This among other improvements allows to compile code with
64-bit divisions, see [1].

We do real CPU clock measurement with help of built-in
counters. Thus we may accommodate different real clock values
that appear in different FPA images instead of relying on
something hard-coded in the .dtb.

And while at it make make SDIO base address define
look similar to others with casting to "(void *)".
