c618bb0042 rockchip: Setup dwc3_device (for non-dm gadgets)
Setup dwc3_device structure for non-dm gadgets, which is used
in rk3399 platforms.

dwc3_device would have basic regbase, dr_mode, high speed
and 16-bit UTMI+ etc.

66b3ccc8f7 tools: checkpatch: Restore 'debug' and 'printf' to logFunctions list
The 'debug' and 'printf' functions were previously added to the list of
logFunctions in commit 0cab42110d ("checkpatch.pl: Add 'debug' to
the list of logFunctions") and commit 397bfd4642 ("checkpatch.pl:
Add 'printf' to logFunctions") but these additions were lost when newer
versions of checkpatch were pulled in from the upstream Linux
kernel version.

This restores them so that you don't end up in a situation where
checkpatch will give a warning for "quoted string split across lines"
which you cannot fix without getting a warning for "line over 80
characters" instead.

6b7ebff001 usb: dwc3: Add phy interface for dwc3_uboot
U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
  call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
  call dwc3_uboot_init in core.

The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.

So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.

This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.

This change used Linux phy.h enum list, to make proper code
compatibility.

- Add ENV_xxx_REDUND options that depend on their primary option and
  SYS_REDUNDAND_ENVIRONMENT
- On a number of PowerPC platforms, use SPL_ENV_ADDR not CONFIG_ENV_ADDR
  for the pre-main-U-Boot environment location.
- On ENV_IS_IN_SPI_FLASH, check not for CONFIG_ENV_ADDR being set but
  rather it being non-zero, as it will now be zero by default.
- Rework the env_offset absolute in env/embedded.o to not use
  CONFIG_ENV_OFFSET as it was the only use of ENV_OFFSET within
  ENV_IS_IN_FLASH.
- Migrate all platforms.

Pull request for UEFI sub-system for efi-2020-01-rc4

Fix errors due to unaligned memory access:
* disable UEFI except for ARMv8, ARMv7, ARM11
* enable unaligned access support on ARM11

Remove an unused function.

38064ee04c efi_loader: enable EFI_LOADER on arm1136 and arm1176
With an implementation for allow_unaligned() available for arm1136 and
arm1176 UEFI can be supported on these architectures.

d47a774680 arm: arm11: allow unaligned memory access
The UEFI spec mandates that unaligned memory access should be enabled if
supported by the CPU architecture.

This patch implements the function unaligned_access() to set the enable
unaligned data support flag and to clear the aligned flag in the system
control register (SCTLR). It is called when UEFI related commands like
bootefi are invoked.

b20bb09b21 efi_loader: restrict EFI_LOADER to armv7 and armv8 on ARM
fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().

UEFI on ARM requires that unaligned memory access is enabled.

* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
  U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
  which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
  For none of the other cpus in arch/arm/cpu/ we have implemented a
  similar function.
* ARMv8 allows unaligned access.

Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.

Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.
