Currently generic-asm-offsets.h and asm-offsets.h are generated based
on U-Boot proper config options. The same asm-offsets headers are used
for building U-Boot SPL/TPL, which causes potential offset mismatch if
U-Boot proper has different config options from U-Boot SPL/TPL.

This commit adds:
  spl/include/generated/(generic-)asm-offsets.h
  tpl/include/generated/(generic-)asm-offsets.h

spl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_SPL=y, and included when building SPL.

tpl/include/generated/(generic-)asm-offsets.h is generated if
CONFIG_TPL=y, and included when building TPL.

They are created before Kbuild descends into SPL/TPL object directories
and builds $(obj)/dts/dt-platdata.o because $(obj)/dts/dt-platdata.c
includes a bunch of headers.

Prepend -I$(obj)/include to $(UBOOTINCLUDE) so (generic-)asm-offsets.h
is searched in {spl,tpl}/include/generated/.

Assert reset before deassert in dwc2_reset;
this patch solve issues when the DWC2 registers are already
initialized with value incompatible with host mode.

Force a hardware reset of the IP reset all the DWC2 registers at
default value, the host driver start with a clean state
(Core Soft reset doen in dwc_otg_core_reset is not enought
 to reset all register).

The error can occurs in U-Boot when DWC2 device gadget driver
force device mode (called by ums or dfu command, before to execute
the usb start command).

Power on/off the PHYs to enable power to the USB ports, fixing USB support
on Khadas VIM3/VIM3L boards.

The G12A USB complex has at least 2 USB2 PHYs, but one is muxed between the
DWC2 and DWC3 controller and the other one directly connected to the DWC3
controller. The USB3+PCIe combo PHY is muxed between the DWC3 controller
and a DW-PCIE controller.
All PHYs are optional, but it's type (usb2/usb3) and position are important
to determine it's capabilities, thus they are stored in a fixed size
array and the phy-name determines it's position, it's position determining
it's type and functionnalities.
This is why we need to loop over the array to power on all the DT provided
PHYs.

Here we introduce new development platfrom for ARC: HSDK 4xD.
That's pretty much the same base-board as in HSDK but with
very recent quad-core ARC HS47D in the ASIC.

Thus we try to re-use existing code as much as possible while
inevitably add some pieces needed for the new ASIC.

Also we drop selection of bounce buffers on AXS10x
as there's no use of them any longer.

At this point LLVM-7 is rather old.  Switch over to LLVM-10 to enable
some amount of CI coverage with newer compilers.

As u-boot doesn't support the metadata_csum feature, writing to a
filesystem with this feature enabled will fail, as expected. However,
during the process, a journal state check is performed, which could
result in:
  - a fs recovery if the fs wasn't umounted properly
  - the fs being marked dirty

Both these cases result in a superblock change, leading to a mismatch
between the superblock checksum and its contents. Therefore, Linux will
consider the filesystem heavily corrupted and will require e2fsck to be
run manually to boot.

By bypassing the journal state check, this patch ensures the superblock
won't be corrupted if the filesystem has metadata_csum feature enabled.

We have a board with several revisions. The older ones use a nor flash
with 64k erase size, while the newer have a flash with 4k sectors. The
environment size is 8k.

Currently, we have to put a column containing 0x10000 (64k) in
fw_env.config in order for it to work on the older boards. But that
ends up wasting quite a lot of time on the newer boards that could
just erase the 8k occupied by the environment - strace says the 64k
erase takes 0.405 seconds. With this patch, as expected, that's about
an 8-fold better, at 0.043 seconds.

Having different fw_env.config files for the different revisions is
highly impractical, and the correct information is already available
right at our fingertips. So use the erasesize returned by the
MEMGETINFO ioctl when the fourth and fifth columns (sector size and
#sectors, respectively) are absent or contain 0, a case where the
logic previously used to use the environment size as erase size (and
consequently computed ENVSECTORS(dev) as 1).

As I'm only testing this on a NOR flash, I'm only changing the logic
for that case, though I think it should be possible for the other
types as well.
