d28c5920cd include: linux: io: define devm_ioremap on board with ioremap
The macro devm_ioremap is only defined for configuration
that doesn't have ioremap. But this macro may also be
defined on configuration with ioremap.
This patch remove the condition for the macro devm_ioremap,
so it's always defined.

9db29b300f mtd: nand: provide several helpers to do common NAND operations
Linux commit 97d90da8a88 ("mtd: nand: provide several helpers
to do common NAND operations")

This is part of the process of removing direct calls to ->cmdfunc()
outside of the core in order to introduce a better interface to execute
NAND operations.

Here we provide several helpers and make use of them to remove all
direct calls to ->cmdfunc(). This way, we can easily modify those
helpers to make use of the new ->exec_op() interface when available.

Linux commit 28b8b26b308 ("mtd: add get/set of_node/flash_node helpers")

We are going to begin using the mtd->dev.of_node field for MTD device
nodes, so let's add helpers for it. Also, we'll be making some
conversions on spi_nor (and nand_chip eventually) too, so get that ready
with their own helpers.

7fd9f31c6b usb: dwc2: fix gadget disconnect
This fixes a disconnect issue detected with fastboot command, when using
dwc2 driver.
- On u-boot side:
uboot>$ fastboot 0
- On USB host PC side, few seconds after
PC>$ fastboot reboot # Get stuck, uboot target never reboots

By enabling DEBUG_ISR logs, the bus suspend interrupt is seen before the
PC command has been issued. When the USB bus suspend occurs, there's a HACK
that disables the fastboot (composite driver). Here is the call stack
upon USB bus suspend:
- dwc2_handle_usb_suspend_intr()
  - dev->driver->disconnect()
    - composite_disconnect()
      - reset_config()
        - f->disable()
          - fastboot_disable()
            - usb_ep_disable(f_fb->out_ep);
            - usb_ep_disable(f_fb->in_ep);
            .. other disable calls.

When the resume interrupt happens, everything has been disabled, then
nothing happens. fastboot command gets stuck on HOST side.

Remove original HACK, that disconnects the composite driver upon
USB bus suspend. Implement disconnect detection instead:
- check GINTSTS OTG interrupt
- read GOTGINT register
- check GOTGINT, SesEndDet bit (e.g. session end)
This is inspired by what is implemented currently in Linux dwc2 driver.

d73d9fb7e2 fastboot: add support for 'getvar platform'
Our R-Car3 Android userspace relies on the output of 'fastboot
getvar platform' and U-Boot currently is not able to handle it:

host $> fastboot getvar platform
getvar:platform FAILED (remote: Variable not implemented)
finished. total time: 0.001s

We either have the option of adding 'fastboot.platform' variable
to the default/saved environment as a workaround or add proper
'fastboot getvar platform' support in U-Boot via this patch.
In the latter case, other platforms can benefit from it too.

Note that R-Car3 already exports 'platform' environment variable via
v2019.01 commit 00e4b57e9e ("ARM: rmobile: Set environment variable
containing CPU type").

6fe7dd3327 stm32mp1: add stusb1600 support for DK1 and DK2 board
The DK1 and DK2 boards use the USB Type-C controller STUSB1600.
This patch updates:
- the device tree to add the I2C node in the DT
- the board stm32mp1 to probe this I2C device and use this controller
  to check cable detection.
- the DWC2 driver to support a new dt property
  "u-boot,force-b-session-valid" which forces B session and
  device mode; it is a workaround because the VBUS sensing and
  ID detection isn't available with stusb1600.

e09c1a1331 timer: dw-apb: Add missing 64bit up-conversion
The generic timer count is an incrementing 64bit value and a timer driver
must return an incrementing 64bit value. The DW APB timer only provides a
32bit timer counting down, thus the result must be inverted and converted
to a 64bit value. The current implementation is however missing the 64bit
up-conversion and this results in random timer roll-overs, which in turn
triggers random timeouts throughout the codebase.

This patch adds the missing 64bit up-conversion to fix the issue.

2c494e62c3 arm: dts: Stratix10: Add QSPI node
Merge qspi dts node from Linux.
Commit 0cb140d07fc75fb (arm64: dts: stratix10: Add QSPI support for Stratix10)

Add -u-boot.dtsi files for non Linux dts properties and
update properties for Uboot.
- add u-boot,dm-pre-reloc
- add alias for spi0
- change compatible for flash
- support quad read and quad write
- change maximum frequency to 100MHz

Tested on Stratix 10 SoC devkit.
SOCFPGA_STRATIX10 # sf probe 0:0
SF: Detected mt25qu02g with page size 256 Bytes, erase size 64 KiB, total 256 MiB

456d45261b ddr: altera: Stratix10: Add ECC memory scrubbing
Scrub memory content if ECC is enabled and it is not
from warm reset boot.

Enable icache and dcache before scrub memory
and use "DC ZVA" instruction to clear memory
to zeros. This instruction writes a cache line
at a time and it can prevent false ECC error
trigger if write cache line partially.

62e6278d1e arm: dts: Stratix10: Modify stratix10 socdk memory node
The stratix10 socdk ships with 4GB of memory.  Modify the
device tree to represent this.  Note that to access 4GB of
memory in Stratix 10, due to the IO space from 2GB to 4GB,
we use the fact that the DDR controller ignores upper address
bits outside of the configured DRAM's size.  This means that
, the 4GB DRAM is mapped to memory every 4GB.

For an 8GB memory, you can either live with the 2GB IO space,
and loose access to that memory from the processor, or use
the same trick:

Loose 2GB of memory:
        memory {
                device_type = "memory";
                /* 8GB */
		/* first 2GB */
                reg = <0 0x00000000 0 0x80000000>,
		/* last 4GB */
                      <1 0x00000000 1 0x00000000>;
                u-boot,dm-pre-reloc;
        };

or to map it all:
        memory {
                device_type = "memory";
                /* 8GB */
		/* first 2GB */
                reg = <0 0x00000000 0 0x80000000>,
		/* next 6GB */
                      <2 0x80000000 1 0x80000000>;
                u-boot,dm-pre-reloc;
        };

6cd7134e73 ddr: altera: Stratix10: Add multi-banks DRAM size check
Stratix 10 maps dram from 0 to 128GB.  There is a 2GB hole
in the memory for peripherals and other IO from 2GB to 4GB.
However the dram controller ignores upper address bits for
smaller dram configurations.  Example: a 4GB dram
maps to multiple locations, every 4GB on the address.

c5de2b7eae arm: socfpga: implement proper peripheral reset
This commit removes ad-hoc reset handling for peripheral resets from SPL
for socfpga gen5.

This is done because as U-Boot drivers support reset handling by now.
