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

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

ada8affdfe ARC: HSDK: Add platform-specific commands
This patch add support of hsdk platform-specific commands:

hsdk_clock set - set clock from axi_freq, cpu_freq and tun_freq
environment variables/command line arguments

hsdk_clock get - save clock frequencies to axi_freq, cpu_freq
and tun_freq environment variables

hsdk_clock print - show CPU, AXI, DDR and TUNNEL current
clock frequencies.

hsdk_clock print_all - show all currently used clock frequencies.

hsdk_init - setup board HW in one of pre-defined configuration
(hsdk_hs34 / hsdk_hs36 / hsdk_hs36_ccm / hsdk_hs38 /
hsdk_hs38_ccm / hsdk_hs38x2 / hsdk_hs38x3 / hsdk_hs38x4)

hsdk_go - run baremetal application on hsdk configured
by hsdk_init command.

This patch changes default behaviour of 'bootm' command:
now we are able to set number of CPUs to be kicked by setting
'core_mask' environment variable before 'bootm' command run.

4e782b5940 ARC: HSDK: Fixup DW SDIO CIU frequency to 50000000Hz
DW SDIO controller has external CIU clock divider controlled via
register in the SDIO IP. Due to its unexpected default value
(we expected it to divide by 1 but in reality it divides by 8)
SDIO IP uses wrong CIU clock (it should be 100000000Hz but actual
is 12500000Hz) and works unstable (see STAR 9001204800).

So increase SDIO CIU frequency from actual 12500000Hz to 50000000Hz
by switching from the default divisor value (div-by-8) to the
minimum possible value of the divisor (div-by-2) in HSDK platform
code.

2a5062ca9e axs103: Support slave core kick-start on axs103 v1.1 firmware
In axs103 v1.1 procedure to kick-start slave cores has changed quite a bit
compared t previous implementation.

In particular:
 * We used to have a generic START bit for all cores selected by CORE_SEL
   mask. But now we don't touch CORE_SEL at all because we have a dedicated
   START bit for each core:
     bit 0: Core 0 (master)
     bit 1: Core 1 (slave)
 * Now there's no need to select "manual" mode of core start

Additional challenge for us is how to tell which axs103 firmware we're
dealing with. For now we'll rely on ARC core version which was bumped
from 2.1c to 3.0.

0c77092e81 arc: dts: separate single axs10x.dts file
We want to use the same device tree blobs in both Linux and U-Boot for
ARC boards.

Earlier device tree sources in U-Boot were very simplified and hadn't been
updated for quite a long period of time.

So this commit is the first step on the road to unified device tree blobs.

First of all we re-organize device tree sources for AXS10X boards.
As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and
AXC003 cpu tiles respectively we add corresponding device tree source
files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for
cpu tiles and axs101.dts and axs103.dts to represent actual boards.

Also we delete axs10x.dts as it is no longer used.

One more important change - we add timer device to ARC skeleton device
tree sources as both ARC700 and ARCHS cores contain such timer.
We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree
sources as it is referenced via phandle from timer node in common
skeleton.dtsi file.

65fcba1251 arc: Rename AXS101 board to more generic AXS10x
As of now we have 2 flavors of ARC SDP boards:
 1) AXS101 - with ARC770 in ASIC
 2) AXS103 - with ARC HS38 in FPGA

Both options share exactly the same base-board and only differ with
CPU-tiles in use. That means all peripherals are the same (they are
implemented in FPGA on the base-board) and so generic board could be
used for both.

While at it:
 * Recreated defconfigs with savedefconfig
 * In include/configs/axs10x.h numerical sizes replaced with
defines from linux/sizes.h for better readability.

cc8be222d1 arc: Rename ARCangel4 board to nSIM

c7d8db66ff board: axs10x: Flush entire cache after programming reset vector
Now when we have support of IOC (IO-Coherency block) cahce operations
on regions are tuned to not be dummy stubs if IOC was found and enabled
in the core. That makes flush_dcache_range() useless for our purposes
here. And since we do need to flush modified reset vector to at least L2
cache (AKA SLC) so other cores will see it via its L1 instruction cache
we're using always functional flush_dcache_all() here.

8b2eb776b1 arc: implement slave cores kick-start for Linux kernel
With new SMP-enabled CPUs with ARC HS38 cores and corresponding support
in Linux kernel it's required to add basic SMP support in U-Boot.

Currently we assume the one and only core starts execution after
power-on. So most of things in U-Boot is handled in UP mode.

But when U-Boot is used for loading and starting Linux kernel right
before jumping to kernel's entry point U-Boot:
 [1] Sets all slave cores to jump to the same address [kernel's entry
point]
 [2] Really starts all slav cores

In ARC's implemetation of SMP in Linux kernel all cores are supposed to
run the same start-up code. But only core with ID 0 (master core)
processes further while others are looping waiting for master core to
complete some initialization.

That means it's safe to un-pause slave cores and let them execute kernel
- they will wait for master anyway.

while

They are almost the same except data bus width 8-bit in [1] and 16-bit
in [2]. And for proper support of 16-bit data bus we have to pass
NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

f39b2a6e88 axs101: fix dw gmac instantiation for updated dw gmac driver
With accepted change to DW GMAC driver -
92a190aaab (net/designware - switch driver
to phylib usage) we need to update this board because
"designware_initialize" now accepts only 2 parameters instead of 4.
