5602330df0 ARM: rmobile: Add recovery SPL for R-Car Gen3
Build an SPL which can be started via SCIF download mode on R-Car Gen3
and allows loading and executing U-Boot uImage with the next stage code.
This is also useful for starting e.g. ATF BL2, which inits the hardware
and returns to the U-Boot SPL, which can then load e.g. U-Boot proper.

The H3, M3-W, M3-N SoCs have plenty of SRAM for storing the U-Boot SPL
while the payload, e.g. ATF BL2, executes, so there is no problem here.

However, E3 and D3 have much less SRAM, hence the loader uses a trick
where it copies itself beyond the area used by BL2 and executes from
there. That area is 32kiB large and not enough to hold U-Boot SPL, BSS,
stack and malloc area, so the later two are placed at +0x4000 offset
from start of SRAM, another area not used by ATF BL2. To make things
even more complicated, the SCIF loader cannot load to the upper 32kiB
of the SRAM directly, hence the copying approach.

ff3bb0c435 mpc83xx: Get rid of CONFIG_83XX_CLKIN
MPC83xx uses CONFIG_83XX_CLKIN instead of CONFIG_SYS_CLK_FREQ to set the

* replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ
* set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all
  MPC83xx config files

0f06f57c28 mpc83xx: Replace CONFIG_83XX_CLKIN in calculations
CONFIG_SYS_CLK_FREQ is the standard way to set the system clock
frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose.
Hence, the obvious way is to replace CONFIG_83XX_CLKIN with
CONFIG_SYS_CLK_FREQ.

A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing
CONFIG_SYS_NS16550_CLK. This makes it harder to replace
CONFIG_83XX_CLKIN.

But the value of the multiplicator can be read from the SPMR register.

Hence, replace the static calculations with a call to a new get_bus_freq
function, as other architectures do.

26f8e0d7f2 arm: sunxi: h6: fix reset using r_wdog
Some H6 boards have a watchdog which didn't make the SoC
reboot properly.

Reason is still unknown but several people have test it.
Chen-Yu Tsai :
Pine H64 = H6 V200-AWIN H6448BA 7782 => OK
OrangePi Lite 2 = H6 V200-AWIN H8068BA 61C2 => KO

Martin Ayotte :
Pine H64 = H8069BA 6892 => OK
OrangePi 3 = HA047BA 69W2 => KO
OrangePi One Plus = H7310BA 6842 => KO
OrangePi Lite2 = H6448BA 6662 => KO

Clément Péron:
Beelink GS1 = H6 V200-AWIN H7309BA 6842 => KO

After the series of result, Icenowy try to reach Allwinner about this
issue but they seems not interested to investigate it.

As we don't have the ARIS coproc to do power management and watchdogis
the only solution to reset the board.

So, Change from watchdog to R_watchdog to allow a reboot on all H6
boards.

not scanned, so the UART node is missing (and others).

I'm not adding this property in an *u-boot.dtsi file, since there is
none matching the generic rules for all files including this dtsi
file. So to not miss any of the boards using this dtsi file, I'm
adding it to this file directly, which makes the Linux merge a less
easy unforunately.

a0aba8a2eb CONFIG_SYS_[DI]CACHE_OFF: convert to Kconfig
CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig
parameters; only for the ARC architecture. This patch turns these two
parameters into Kconfig items everywhere else they are found.

All of the include/configs/* and defconfig changes in this patch are
for arm machines only. The Kconfig changes for arc, nds32, riscv,
and xtensa have been included since these symbols are found in code
under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined
include/configs/* or defconfigs for these architectures exist which
include these symbols.

These results have been confirmed with tools/moveconfig.py.

b7b4af0e35 CONFIG_SYS_[ID]CACHE_OFF: unify the 'any' case
According to De Morgan's Law[1]:
	!(A && B) = !A || !B
	!(A || B) = !A && !B

There are 5 places in the code where we find:
	#if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
and 4 places in the code where we find:
	#if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF))

In words, the construct:
	!defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
	"is the [DI]CACHE on?"
and the construct:
	defined(CONFIG_SYS_[DI]CACHE_OFF)
means:
	"is the [DI]CACHE off?"

Therefore
	!(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF))
means:
	"the opposite of 'are they both off?'"
in other words:
	"are either or both on?"
and:
	(!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)
means:
	"are either or both on?"

As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for
consistency.

commit c5de2b7eae ("arm: socfpga: implement proper peripheral reset")

socfpga gen5 SPL since the reset driver now handles resets. However,
commit c1d4b464c8 ("ARM: socfpga: Disable bridges in SPL unless booting from FPGA")
has re-added this ad-hoc reset code, so that all peripherals were now
again enabled instead of letting the drivers enable them by request.

While at it, remove this function for gen5 as it should not be used.

  Card did not respond to voltage select!

It may be because the existing driver can't support gpio
card detection. So, change the pinctrl functionality from
RK_FUNC_GPIO to RK_FUNC_1 like other rk3399 dts does via
sdmmc_cd pin.

It depends on the following kernel patch which adds the header to the
flat Image. Gzip compressed Image (Image.gz) support is not enabled with
this patch.

https://patchwork.kernel.org/patch/10925543/

Tested on HiFive Unleashed and QEMU.

83f71ef558 net: phy: micrel: Use correct skew values on KSZ9021
Commit ff7bd212cb ("net: phy: micrel: fix divisor value for KSZ9031
phy skew") fixed the skew value divisor for the KSZ9031, but left the
code using the same divisor for the KSZ9021, which is incorrect.

The preceding commit c16e69f702 ("net: phy: micrel: add documentation
for Micrel KSZ90x1 binding") added the DTS documentation for the
KSZ90x1, changing it from the equivalent file in the Linux kernel to
correctly state that for this part the skew value is set in 120ps steps,
whereas the Linux documentation and driver continue to this day to use
the incorrect value of 200 that came from the original KSZ9021 datasheet
before it was corrected in revision 1.2 (Feb 2014).

This commit sorts out the resulting confusion in a consistent way by
making the following changes:

- Update the documentation to be clear about what the skew values mean,
in the same was as for the KSZ9031.

- Update the Micrel PHY driver to select the appropriate divisor for
both parts.

- Adjust all the device trees that state skew values for KSZ9021 PHYs to
use values based on 120ps steps instead of 200ps steps. This will result
in the same values being programmed into the skew registers as the
equivalent device trees in the Linux kernel do, where it incorrectly
uses 200ps steps (since that's where all these device trees were copied
from).

997b857ae3 sun50i: a64: Add Olimex A64-Teres-I board initial support
Olimex A64-Teres-I board is a mainboard (the only one so far)
for Olimex Teres-I DIY laptop kit.

Key features:
- Allwinner A64 Cortex-A53
- Mali-400MP2 GPU
- AXP803 PMIC
- 2GB DDR3 RAM
- MicroSD Slot
- 16GB eMMC Flash
- eDP LCD display
- HDMI
- USB Host
- Battery management
- 5V DC power supply
- Certified Open Source Hardware (OSHW)

Works:
- i2C
- MMC/SD
- PWM backlight

Known broken:
- Internal keyboard (seems to be because the keyboard firmware loads a
bootloader first, and then disconnects bootloader and connect real
keyboard). External ones connected to the USB port work fine.

This patch enables support for the A64-Teres-I board to u-boot,
including enabling screen backlight (lacking from Linux device-tree).

Devicetree files in RK3399 platform is synced from Linux, like other
platforms does. Apart from these u-boot in rk3399 would also require
some u-boot specific node like dmc.

dmc node has big chunk of DDR timing parameters which are specific
to specific board, and maintained with rk3399-sdram*.dtsi.

So, create board specific -u-boot.dtsi files and move these sdram dtsi
files accordingly. This would help of maintain u-boot specific changes
separately without touching Linux dts(i) files which indeed easy for
syncing from Linux between releases.

These board specific -u-boot.dtsi can be extendible to add more u-boot
specific nodes or properties in future.

- Sometimes u-boot specific dtsi files are included

  family of rockchip SoC.
- Sometimes u-boot specific dts nodes or properties can use
  config macros from respective rockchip family include/configs
  files, example CONFIG_SPL_PAD_TO.

So, it's better to compile the dtbs based on the respective
rockchip family types rather than rockchip itself to avoid
compilation issues.

This patch organize the existing dtb's based on the rockchip

051c31b7a4 x86: Add support for starting from SPL/TPL
When a previous phase of U-Boot has run we need to adjust the init of
subsequent states to avoid messing up the CPU state.

Add a new version of the start logic for SPL, when it boots from TPL
(start_from tpl.c) and a new version for U-Boot when it boots from SPL.

4eabf1e54b x86: broadwell: Allow SDRAM init from SPL
At present, for broadwell, SDRAM is always set up in U-Boot proper since
the 64-bit mode (which uses SDRAM init in SPL) is not supported.

Update the code to allow SDRAM init in SPL instead so that U-Boot proper
can be loaded into SDRAM and run from there. This allows U-Boot to be
compressed to reduce space, since it is not necessary to run it directly
from flash. It could later allow us to support 64-bit U-Boot on broadwell.
