c5edefb7f7 x86: Update device tree for Chromium OS verified boot
The standard image generated by U-Boot on x86 is u-boot.rom. Add a
separate image called image.bin for verified boot. This supports
verification in TPL of which SPL/U-Boot to start, then jumping to the
correct one, with SPL setting up the SDRAM and U-Boot proper providing
the user interface if needed.

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.

ba932bc846 ARM: dts: renesas: Add RZ/A1 GR-Peach board
Add board code and DTs for Renesas RZ/A1 SoC-based GR-Peach,
which is a cheap development platform with RZ/A1H SoC. The
DTs are imported from Linux 5.0.11, commit d5a2675b207d .

Currently supported are UART, ethernet and RPC SPI. The board
can be booted from RPC SPI by writing the u-boot.bin binary
to the beginning of the SPI NOR, e.g. using the "sf" command.
The board can also be booted via JTAG by setting text base to
0x20020000, loading u-boot.bin there via JTAG and executing it
from that address.

add4967124 arch: armv8: Provide a way to disable cache maintenance ops
On AM654 SoC(arm64) which is IO coherent and has L3 Cache, cache
maintenance operations being done to support non-coherent platforms
causes issues.

For example, here is how U-Boot prepares/handles a buffer to receive
data from a device (DMA Write). This may vary slightly depending on the
driver framework:

	Start DMA to write to destination buffer
	Wait for DMA to be done (dma_receive()/dma_memcpy())
	Invalidate destination buffer (invalidate_dcache_range())
	Read from destination buffer

The invalidate after the DMA is needed in order to read latest data from
memory that’s updated by DMA write. Also, in case random prefetch has
pulled in buffer data during the “wait for DMA” before the DMA has
written to it. This works well for non-coherent architectures.

In case of coherent architecture with L3 cache, DMA write would directly
update L3 cache contents (assuming cacheline is present in L3) without
updating the DDR memory. So invalidate after “wait for DMA” in above
sequence would discard latest data and read will cause stale data to be
fetched from DDR. Therefore invalidate after “wait for DMA” is not
always correct on coherent architecture.

Therefore, provide a Kconfig option to disable cache maintenance ops on
coherent architectures. This has added benefit of improving the
performance of DMA transfers as we no longer need to invalidate/flush
individual cache lines(especially for buffer thats several KBs in size).

In order to facilitate use of same Kconfig across different
architecture, I have added the symbol to top level arch/Kconfig file.
Patch currently disables cache maintenance ops for arm64 only.
flush_dcache_all() and invalidate_dcache_all() are exclusively used
during enabling/disabling dcache and hence are not disabled.

7225a27ffa delete Kbuild "select" of long-dead SPL_DISABLE_OF_CONTROL
>From way back in 2015:

  commit dffb86e468
  Author: Masahiro Yamada <yamada.masahiro@socionext.com>
  Date:   Wed Aug 12 07:31:54 2015 +0900

    of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL

    As we discussed a couple of times, negative CONFIG options make our
    life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
    and here is another one.

    Now, there are three boards enabling OF_CONTROL on SPL:
     - socfpga_arria5_defconfig
     - socfpga_cyclone5_defconfig
     - socfpga_socrates_defconfig

    This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
    CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
    the logic.

The support for DaVinci DM* SoCs has been dropped a while ago. There's
still a lot of leftover code in mach-davinci though. Entirely remove
certain files and modify the common code to no longer reference
unsupported chips.

Note: all DaVinci platforms supported in u-boot now define SOC_DA8XX
but not all define SOC_DA850 (e.g. omapl138). We can safely remove
all ifdefs for the former, but let's leave the ones for the latter.

Currently mach-mt7620 contains only support for mt7628. To avoid confusion,
rename mach-mt7620 to mach-mtmips, which means MediaTek MIPS platforms.
MT7620 and MT7628 should be distinguished by SOC_MT7620 and SOC_MT7628
because they do not share the same lowlevel codes.

Dependencies of four drivers are changed to SOC_MT7628 as these drivers
are only used by MT7628.

6943cc9732 arch: mips: Update initrd_start and initrd_end
Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which
represents the start of kseg0 and represents a virtual address. Meaning
that the initrd_start and initrd_end point somewhere kseg0.
When these parameters are passed to linux kernel through DT
they are pointing somewhere in kseg0 which is a virtual address but linux
kernel expects the addresses to be physical addresses(in kuseg) because
it is converting the physical address to a virtual one.

Therefore update the uboot to pass the physical address of initrd_start
and initrd_end by converting them using the function virt_to_phys before
setting up the DT.

539f0242f3 arm: mvebu: turris_omnia: add RESET button handling
There is a Factory RESET button on the back side of the Turris Omnia
router. When user presses this button before powering the device up and
keeps it pressed, the microcontroller prevents the main CPU from booting
and counts how long the RESET button is being pressed (and indicates
this by lighting up front LEDs).

The idea behind this is that the user can boot the device into several
Factory RESET modes.

This patch adds support for U-Boot to read into which Factory RESET mode
the user booted the device. The value is an integer stored into the
omnia_reset environment variable. It is 0 if the button was not pressed
at all during power up, otherwise it is the number identifying the
Factory RESET mode.

This patch also changes bootcmd to a special hardcoded value if Factory
RESET button was pressed during device powerup. This special bootcmd
value sets the colors of all the LEDs on the front panel to green and
then tries to load the rescue image from the SPI flash memory and boot
it.

e05b4a4fa8 rockchip: dts: rk3399: Create initial rk3399-u-boot.dtsi
u-boot,dm-pre-reloc is required for SDMMC booted rk3399 boards and
which is U-Boot specific devicetrees binding.

Move it on global rk3399-u-boot.dtsi file and rest of the U-Boot
bindings will move it future based on the requirement.

This would help to sync the devicetrees from Linux whenever required
instead of adding specific nodes.

Booting this board failed as the initial console isn't found since
commit c402e81702 ("dts: arm: socfpga: merge gen5 devicetrees from linux")

The uart0 devicetree entry was missing "clock-frequency = <100000000>:"
since that commit

c5f4b80575 ARM: socfpga: Remove socfpga_sdram_apply_static_cfg()
The usage of socfpga_sdram_apply_static_cfg() seems rather dubious and
is confirmed to lead to a rare system hang when enabling bridges. This
patch removes the socfpga_sdram_apply_static_cfg() altogether, because
it's use seems unjustified and problematic.

The socfpga_sdram_apply_static_cfg() triggers write to SDRAM staticcfg
register to set the applycfg bit, which according to old vendor U-Boot
sources can only be written when there is no traffic between the SDRAM
controller and the rest of the system. Empirical measurements confirm
this, setting the applycfg bit when there is traffic between the SDRAM
controller and CPU leads to the SDRAM controller accesses being blocked
shortly after.

Altera originally solved this by moving the entire code which sets the
staticcfg register to OCRAM [1]. The commit message claims that the
applycfg bit needs to be set after write to fpgaportrst register. This
is however inverted by Altera shortly after in [2], where the order
becomes the exact opposite of what commit message [1] claims to be the
required order. The explanation points to a possible problem in AMP
use-case, where the FPGA might be sending transactions through the F2S
bridge.

However, the AMP is only the tip of the iceberg here. Any of the other
L2, L3 or L4 masters can trigger transactions to the SDRAM. It becomes
rather non-trivial to guarantee there are no transactions to the SDRAM
controller.

The SoCFPGA SDRAM driver always writes the applycfg bit in SPL. Thus,
writing the applycfg again in bridge enable code seems redundant and
can presumably be dropped.
