45254edd94 mmc: fsl_esdhc_imx: remove redundant ARCH_MXC
Now original fsl_esdhc.c are split as fsl_esdhc.c and fsl_esdhc_imx.c.
fsl_esdhc_imx.c only cover i.MX SoC. So ARCH_MXC is redundant.

1a7904fdfa mmc: fsl_esdhc_imx: Use esdhc_soc_data flags to set host caps
The Linux driver automatically can detect and enable UHS, HS200, HS400
and HS400_ES automatically without extra flags being placed into the
device tree.

Right now, for U-Boot to use UHS, HS200 or HS400, the extra flags are
needed in the device tree.  Instead, go through the esdhc_soc_data
flags and enable the host caps where applicable to automatically
enable higher speeds.

a163db9fba ddr: marvell: a38x: fix BYTE_HOMOGENEOUS_SPLIT_OUT decision
In commit 3fc92a215b69 ("ddr: marvell: a38x: fix SPLIT_OUT_MIX state
decision") I ported a cleaned up and changed version of patch
  mv_ddr: a380: fix SPLIT_OUT_MIX state decision

In the port we removed checking for BYTE_HOMOGENEOUS_SPLIT_OUT bit,
because:
- the fix seemed to work without it
- the bit was checked for only at one place out of two, while the second
  bit, BYTE_SPLIT_OUT_MIX, was checked for in both cases
- without the removal it didn't work on Allied Telesis' x530 board

We recently had a chance to test on more boards, and it seems that the
change needs to be opposite: instead of removing the check for
BYTE_HOMOGENEOUS_SPLIT_OUT from the first if() statement, the check
needs to be added also to the second one - it needs to be at both
places.

With this change all the Turris Omnia boards I have had available to
test seem to work, I didn't encounter not even one failed DDR training.

As last time, I am noting that I do not understand what this code is
actually doing, I haven't studied the DDR training algorithm and
I suspect that no one will be able to explain it to U-Boot contributors,
so we are left with this blind poking in the code with testing whether
it works on several boards and hoping it doesn't break anything for
anyone :-(.

2a9059aef5 arm: a37xx: pci: Ensure that root port is always on root zero bus
Writing to the PCI_PRIMARY_BUS register of the root port should not change
bus number on which is root port present.

This PCI_PRIMARY_BUS register is used only for correct configuration of
legacy PCI stuff, like forwarding of PCI special cycles between buses.

Aardvark HW does not support PCI special cycles, so it does not have HW
register for PCI_PRIMARY_BUS and therefore it does not matter what is
stored in this register.

So fix this issue and do not use PCI_PRIMARY_BUS register in pci-aardvark.c
driver for moving root bus of the root port.

After this change there is no reason for storing bus number (zero) into
first_busno variable, so remove this variable.

d5daa02d8d usb: xhci: reset endpoint on USB stall
There are devices which cause a USB stall when trying to read strings.
Specifically Arduino Mega R3 stalls when trying to read the product
string.

The stall currently remains unhandled, and subsequent retries submit new
transfers on a stopped endpoint which ultimately cause a crash in
abort_td():
WARN halted endpoint, queueing URB anyway.
XHCI control transfer timed out, aborting...
Unexpected XHCI event TRB, skipping... (3affe040 00000000 13000000 02008401)
BUG at drivers/usb/host/xhci-ring.c:505/abort_td()!

resetting ...

Linux seems to be able to recover from the stall by issuing a
TRB_RESET_EP command.

Introduce reset_ep() which issues a TRB_RESET_EP followed by setting the
transfer ring dequeue pointer via TRB_SET_DEQ. This allows to properly
recover from a USB stall error and continue communicating with the USB
device.

078dfef931 usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mn
The imx8mm and imx8mn appear compatible with imx7d-usb
flags in the OTG driver.  If the dr_mode is defined as
host or peripheral, the device appears to operate correctly,
however the auto host/peripheral detection results in an error.

The solution isn't just adding checks for imx8mm and imx8mn to
the check for imx7, because the USB clock needs to be running
to read from the USBNC_PHY_STATUS_OFFSET register or it will hang.

Marek requested that I not enable the clocks in ehci_usb_of_to_plat,
so I modified that function to return an unknown state if the
device tree does not explicitly state whether it is a host
or a peripheral.

When the driver probes, it looks to see if it's in the unknown
state, and only then will it read the register to auto-detect.

ca99a17e02 nvme: Add shutdown function
Add a function to disable the NVMe controller. This will be used
to let the driver for the NVMe storage integrated on Apple SoCs
shutdown the NVMe controller such we can shutdown the NVMe
IOP controller in a clean way afterwards before handing control
to the OS.

19d9dad39c nvme: Introduce driver ops
The NVMe storage controller integrated on Apple SoCs deviates
from the NVMe standard in two aspects.  It uses a "linear"
submission queue and it integrates an NVMMU that needs to be
programmed for each NVMe command.  Introduce driver ops such
that we can set up the linear submission queue and program the
NVMMU in the driver for this strange beast.

456305ec59 mailbox: apple: Add driver for Apple IOP mailbox
This mailbox driver provides a communication channel with the
Apple IOP controllers found on Apple SoCs.  These IOP controllers
are used to implement various functions such as the System
Manegement Controller (SMC) and NVMe storage.  It allows sending
and receiving a 96-bit message over a single channel.

The header file with the struct used for mailbox messages is taken
straight from Linux.

045474be5e nvme: Split out PCI support
Apple SoCs have an integrated NVMe controller that isn't connected
over a PCIe bus. In preparation for adding support for this NVMe
controller, split out the PCI support into its own file. This file
is selected through a new CONFIG_NVME_PCI Kconfig option, so do
a wholesale replacement of CONFIG_NVME with CONFIG_NVME_PCI.

d6ba787e32 serial: Add RISC-V HTIF console driver
Quite a few RISC-V emulators and ISS (including Spike) have host
transfer interface (HTIF) based console. This patch adds HTIF
based console driver for RISC-V platforms which depends totally
on DT node for HTIF register base address.
