eaf6ea6a1d Migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h
- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
  pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
  set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
  GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
  board config header files.

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.

Use register intstead of static variable to store HSDK init status as
we want to avoid the situation when we reload U-boot via MDB after
previous init is done but HW reset (board reset) isn't done. So
let's store the init status in unused register - CREG_CPU_0_ENTRY
so status will survive after U-boot is reloaded via MDB.

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.

336d4615f8 dm: core: Create a new header file for 'compat' features

One of these is malloc.h which we thus end up including in every file in

which needs to use the system malloc() in some files.

 * 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].
