0546b1ab06 arm64: zynqmp: Do not duplicate flash partition label property
In kernel 5.4, support has been added for reading MTD devices via
the nvmem API.
For this the mtd devices are registered as read-only NVMEM providers
under sysfs with the same name as the flash partition label property.

So if flash partition label property of multiple flash devices are identical
then the second mtd device fails to get registered as a NVMEM provider.

This patch fixes the issue by having different label property for different
flashes.

12ffe75819 arm64: zynqmp: Add 'no-1-8-v' property for ZynqMP Boards
Modify dts files to add 'no-1-8-v' property for all the ZynqMP boards.
User can remove this property to enable the UHS mode. This is to keep
the same speed (HS) modes across all the stages of the Linux Boot. Due
to power cycling limitation of some of the ZynqMP boards, some SD cards
don't get power cycled and are failing in Linux.

Most of the legacy "gpio-key,wakeup" boolean property is already
replaced with "wakeup-source". However few occurrences of old property

e14ba8a577 arch: Add explicit linker script for u-boot-elf
Commit f4dc714aaa ("arm64: Turn u-boot.bin back into an ELF file after
relocate-rela")
introduce REMAKE_ELF option to recreate u-boot.elf from u-boot ->
u-boot.bin + DT -> u-boot.elf.

The best is to ilustrate it from make V=1 output
  cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
  cp u-boot-dtb.bin u-boot.bin
aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64  u-boot.bin u-boot-elf.o
  aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000

Last command has no explicit linker script passed that's why toolchain
internal linker script is used.
In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed
behavior by commit
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188
which result in situation that program headers has changed from
(xilinx_zynqmp_mini_defconfig)

Program Headers:
  Type           Offset             VirtAddr           PhysAddr
                 FileSiz            MemSiz              Flags  Align

Xilinx tools like XSDB or Bootgen are using program headers for loading ELF
to the right location and by above binutils change ELF is loaded to
incorrect location.

The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf
recreation which is called when REMAKE_ELF is setup.
By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be
able to use by all archs.

7c02bc9649 ARM: tegra: Add NVIDIA Jetson Nano Developer Kit support
The Jetson Nano Developer Kit is a Tegra X1-based development board. It
is similar to Jetson TX1 but it is not pin compatible. It features 4GB
of LPDDR4, a SPI NOR flash for early boot firmware and an SD card slot
used for storage.

HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0
and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI
Ethernet controller provides onboard network connectivity. NVMe support
has also been added. Env save is at the end of QSPI (4MB-8K).

A 40-pin header on the board can be used to extend the capabilities and
exposed interfaces of the Jetson Nano.

a482f32992 mmc: t210: Fix 'bad' SD-card clock when doing 400KHz card detect
According to the HW team, for some reason the normal clock select code
picks what appears to be a perfectly valid 375KHz SD card clock, based
on the CAR clock source and SDMMC1 controller register settings (CAR =
408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register
divisor of 16 = 375KHz). But the resulting SD card clock, as measured by
the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the
values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR
clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on
T210 when the requested clock is <= 400KHz. Note that as far as I can
tell, the other requests for clocks in the Tegra MMC driver result in
valid SD clocks.

As per the T210 TRM, when running at 3.3v, the SDMMC1 tap/trim and
autocal values need to be set to condition the signals correctly before
talking to the SD-card. This is the same as what's being done in CBoot,
but it gets reset when the SDMMC1 HW is soft-reset during SD driver
init, so needs to be repeated here. Also set autocal and tap/trim for
SDMMC3, although no T210 boards use it for SD-card at this time.

e67243f1a3 video: rockchip: Fix vop modes for rk3399
VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.

These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,

RK3288:

vopb_out: port {
	#address-cells = <1>;
	#size-cells = <0>;
	vopb_out_edp: endpoint@0 {
		reg = <0>;
		remote-endpoint = <&edp_in_vopb>;
	};
	vopb_out_hdmi: endpoint@1 {
		reg = <1>;
                remote-endpoint = <&hdmi_in_vopb>;
        };
        vopb_out_lvds: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&lvds_in_vopb>;
        };
        vopb_out_mipi: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi_in_vopb>;
        };
};

RK3399:

vopb_out: port {
         #address-cells = <1>;
         #size-cells = <0>;
         vopb_out_edp: endpoint@0 {
                reg = <0>;
                remote-endpoint = <&edp_in_vopb>;
         };
         vopb_out_mipi: endpoint@1 {
                reg = <1>;
                remote-endpoint = <&mipi_in_vopb>;
         };
         vopb_out_hdmi: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&hdmi_in_vopb>;
         };
         vopb_out_mipi1: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi1_in_vopb>;
         };
         vopb_out_dp: endpoint@4 {
                reg = <4>;
                remote-endpoint = <&dp_in_vopb>;
         };
};

here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.

The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.

Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.

Add the patch for fixing these vop modes for rk3399.

Use DT /aliases node to establish a stable phandle to the configuration

df7f49ca27 ARM: dts: stm32: Repair SDMMC2 operation
The eMMC uses different pinmux for the top four data lines, use such
a pinmux, otherwise it takes a very long time until the test for 8bit
operation times out. And this is the correct pinmux per schematic too.

7dbafe0634 Merge tag 'arc-last-minute-fixes-for-2020.04' of https://gitlab.denx.de/u-boot/custodians/u-boot-arc
This last minute pull-request is intended to fix some drivers
when used on ARC boards. The problem was introduced by
07906b3dad

What happened while doing one pretty simple improvement to make
U-Boot port more flexible and portable (by switching accessors from
assembly-written to plain C version) we implicitly added 2 problems:

 1. Downgraded accessors from being volatile which signalled to
    the compiler that it's now possible to do all kinds of optimizations
    which may easily include merge of subsequent byte reads/writes into
    word operations. Which is OK for accessing mormal memory but
    breaks operation of peripherals if we access its memory-mapped regs
    in such a "creative" manner.
 2. As a part of assembly-written implementation we had compiler barriers
    in form of the following construction 'asm volatile("" : : : "memory")',
    and we dropped it in C implemntation. This in its turn enabled compiler
    to mess with instruction ordering. Guess what it gives us in the end :)

So with all that we had in some corner-cases veeery funny instruction flows
generated. And in particular it broke DW SPI functionality when we were
writing large amount of data. Funny enough our tests which were writing
small amount of data still worked and only by the chance we caught that
breakage and unrolled that quite interesting loop of unexpected
problems.

The road to hell is paved with good intentions. Amen :)

45bd649511 ARC: IO: add MB for __raw_* memory accessors
We add memory barriers for __raw_readX / __raw_writeX accessors same
way as it is done for readX and writeX accessors as lots of U-boot
driver uses __raw_readX / __raw_writeX instead of proper accessor
with barrier.

It will save us from lot's of debugging in the future and it is OK
as U-Boot is not that performance oriented as real run-time
software like OS or user bare-metal app so we may afford being not
super fast as we only being executed once.

We must use compiler barriers in C-version read/write IO accessors
before and after operation (read or write) so it won't be reordered
by compiler.
