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.

cef443c166 arm: davinci: remove leftover code for dm* SoCs
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.

Switch from using the high priority DMSC transmit message queue used
by the secure R5 MCU island boot context to the low priority message
queue. While the change in priority is irrelevant for the current boot
architecture it however gives us access to a deeper message queue that
will allow us to buffer more messages. This is an important aspect when
sending several messages without requesting and waiting for a response
in a row which is a communication scheme used during core shutdown for
example. See AM654 TISCI User Guide for additional details.

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.

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.

72c347ced8 ARM: socfpga: Add support for selecting bridges in bridge command
Add optional "mask" argument to the SoCFPGA bridge command, to select
which bridges should be enabled/disabled. This allows the user to avoid
enabling bridges which are not connected into the FPGA fabric. Default
behavior is to enable/disable all bridges.

ba2cfcee88 ARM: socfpga: Fully unmap the FPGA bridges from L3 space
Instead of just putting the bridges into reset, fully remove the bridges
from the L3 main bridge space when disabling them by clearing bits in
NIC-301 remap register. Moreover, only touch the 3 LSbits in brgmodrst
register as the rest of the bits are undefined.

c1d4b464c8 ARM: socfpga: Disable bridges in SPL unless booting from FPGA
Disable bridges between L3 Main switch and FPGA unless booting
from FPGA and keep them disabled to prevent glitches and possible
hangs of the L3 Main switch.

The current version of the code could have enabled the bridges
between the L3 Main switch and FPGA for a short period of time
in board_init_f() in case the FPGA was programmed and then again
disable them at the end of board_init_f(). Replace this with a
code which only sets up the handoff registers and let the user
enable the bridges later on.

b85d155199 arm: dts: add missing vexpress device trees
Add the device trees for

* vexpress_ca5x2_defconfig
* vexpress_ca9x4_defconfig
* vexpress_ca15_tc2_defconfig

as available in Linux 5.1 rc5.

We are using the vexpress_ca15_tc2_defconfig and vexpress_ca9x4_defconfig
for Travis testing via QEMU.

The UEFI base Embedded Base Boot Requirements Specification (EBBR) requires
that an embedded board either provides a device tree or an ACPI table.

All block devices are meant to be moved to the driver model. On ARM this
requires a device tree.

c8aac24629 arm: lpc32xx: Fix timer initialization
The match controller register is not cleared during
initialization. However, some bits of this register may reset the TC if
tnMRx match it.

As we can't make any assumption about how U-Boot is launched by the first
stage bootloader (such as S1L) clearing this register ensure that the
timers work as expected.
