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.

237e5880f8 spi: dw: Add SoC-specific compatible strings
This adds SoC-specific compatible strings to all users of the designware
spi device. This will allow for the correct driver to be selected for each
device. Where it is publicly documented, a compatible string for the
specific device version has also been added. Devices without
publicly-documented device versions include MSCC SoCs, and Arc Socs. All
compatible strings except those for SoCFPGAs and some of the versioned
strings have been taken from Linux.

Since SSI_MAX_XFER_SIZE is determined at runtime, this is not strictly
necessary. However, it is a good cleanup and brings things closer to Linux.

a4aa188948 board_f: Factor out bdinfo bi_mem{start, size} to setup_bdinfo
Move all assignments to gd->bd->bi_mem{start,size} to generic code in
setup_bdinfo.

Xtensa architecture is special in this regard as it defines its own
handling of gd->bd->bi_mem{start,size} fields. In order to avoid defining
a weak SDRAM function, let arch_setup_bdinfo overwrite the generic flags.

For ARC architecture, remove ARCH_EARLY_INIT_R from Kconfig since it is
not needed anymore.

Also, use gd->ram_base to populate bi_memstart to avoid an ifdef.

0914011310 command: Remove the cmd_tbl_t typedef
We should not use typedefs in U-Boot. They cannot be used as forward

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.

ffd4c7c2ec dts: switch spi-flash to jedec, spi-nor compatible
There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

The x86 dts are switched in a separate commit since it depends on a change
in fdtdec.

fae3798ac9 ARC: cache: define CONFIG_SYS_CACHELINE_SIZE as ARCH_DMA_MINALIGN
Even though we don't use CONFIG_SYS_CACHELINE_SIZE in ARC-specific code
it is used a lot in different drivers for alignment purposes.

So we define it and make much more drivers at least compilable for ARC.

7181a6d1cf ARC: Fix iteration in arc_xx_version()
"i" gets incremented before we're entering loop body
and effectively we iterate from 1 to 8 instead of 0 to 7.

This way we:
 a) Skip the first line of struct hs_versions
 b) Go over it and access memory beyond the structure

2acc24fc28 Kconfig: Migrate BOUNCE_BUFFER
The bounce buffer is used by a few drivers (most of the MMC drivers)
to overcome limitations in their respective DMA implementation.

This moves the configuration to Kconfig and makes it user-selectable
(even though it will be a required feature to make those drivers
work): the expected usage is for drivers depending on this to 'select'
it unconditionally from their respective Kconfig (see follow-up
patches).

This commit includes a full migration using moveconfig.py to ensure
that each commit compiles.  To ensure bisectability we update
dependencies of various drivers to now select BOUNCE_BUFFER when needed.

85e529fdfc ARC: Improve identification of ARC cores
1. Try to guess a ARC core template that was used
   i.e. not just name a core family but something more
   menaingful like "ARC HS38", "ARC EM11D" etc.

   We do it checking availability of the key differentiation
   features like:
    - Caches (we actually only check for L1 I$ fpr simplicity)
    - XY-memory
    - DSP extensions etc.

2. Identify ARC subsystems

3. Print core clock frequency
