The Lctech Pi F1C200s (also previously known under the Cherry Pi brand)
is a small development board with the Allwinner F1C200s SoC. This is the
same as the F1C100s, but with 64MB instead of 32MB co-packaged DRAM.
Add a defconfig for this board, enabling the most basic features. This
uses the new 64MB memory map, which avoids the very tight memory map we
use for the 32MB F1C100s board(s).
The devicetree file is already in the tree, courtesy of the previous

cores, we skip the new RISC-V bits for now, as sunxi RISC-V support
is still work in progress.
Among smaller cosmetic changes, this adds a SATA regulator node which we
need in U-Boot to get rid of hard-coded GPIOs.
Also this updates the Allwinner F1C100s DTs, enabling USB support, and
also adds the DTs for two new boards.
As before, this omits the non-backwards compatible changes to the R_INTC
controller, to remain compatible with older kernels.

This clock doesn't seem needed but appears in a phandle list used by
ehci-generic.c to bulk enable it. The phandle list comes from linux,
where it is needed for suspend/resume to work [1].
My tests give the same results with or without this patch, but Marek
Vasut found it weird to declare an empty clk_ops [2].
So I adapted the code from linux 6.1-rc8 so that it hopefully works
if it ever has some user. For now, without real use, it seems to
at least not give any errors when called.

arch/arm/dts/rk3399.dtsi has a node
usb_host0_ehci: usb@fe380000 {
compatible = "generic-ehci";
with clocks:
clocks = <&cru HCLK_HOST0>, <&cru HCLK_HOST0_ARB>,
<&u2phy0>;
The first 2 refer to nodes with class UCLASS_CLK, but &u2phy0
has class UCLASS_PHY.
u2phy0: usb2phy@e450 {
compatible = "rockchip,rk3399-usb2phy";
Since clk_get_bulk() only looks for devices with UCLASS_CLK,
it fails with -ENODEV and then ehci_usb_probe() aborts.
The consequence is peripherals connected to a USB 2 port (e.g. in a
Rock Pi 4 the white port, nearer the edge) not being detected.
They're detected if CONFIG_USB_OHCI_GENERIC is selected in Kconfig,
because ohci_usb_probe() does not abort when one clk_get_by_index()
fails, but then they work in USB 1 mode.
rk3399.dtsi comes from linux and the u2phy0 was added[1] to the clock
list in:
commit b5d1c57299734f5b54035ef2e61706b83041f20c

arm64: dts: rockchip: add u2phy clock for ehci and ohci of rk3399
We found that the suspend process was blocked when it run into
ehci/ohci module due to clk-480m of usb2-phy was disabled.
[...]
Suspend concerns don't apply to U-Boot, and the problem with U-Boot
failing to probe EHCI doesn't apply to linux, because in linux
rockchip_usb2phy_clk480m_register makes u2phy0 a proper clock provider
when called by rockchip_usb2phy_probe().
So I can think of a few alternative solutions:
1- Change ehci_usb_probe() to make it more similar to
ohci_usb_probe(), and survive failure to get one clock. Looks a
little harder, and I don't know whether it could break something if
it ignored a clock that was important for something else than
suspend.
2- Change rk3399.dtsi effectively reverting the linux commit
b5d1c57299734f5b54035ef2e61706b83041f20c. This dealigns the .dtsi
from linux and seems fragile at the next synchronisation.
3- Change the clock list in rk3399-u-boot.dtsi or somewhere else.
This survives .dts* sync but may survive "too much" and miss some
change from linux that we might want.
4- Enable CONFIG_USB_OHCI_GENERIC and use the ports in USB 1 mode.
This would need to be made for all boards using rk3399. In a
simple test reading one file from USB storage it gave 769.5 KiB/s
instead of 20.5 MiB/s with solution 2.
5- Trying to replicate linux and have usb2phy somehow provide a clk,
or have a separate clock device for usb2phy in addition to the phy
device.
This patch tries to implement option 5 as Marek Vasut requested in
December 5th. Options 1 and 3 didn't get through [2][3].
It just registers usb2phy as a clock driver (device_bind_driver()
didn't work but device_bind_driver_to_node() did), without any
specific operations, so that ehci-generic.c finds it and is happy. It
worked in my tests on a Rock Pi 4 B+ (rk3399).

According to the dm_serial_ops documentation, pending() should:

And:
> It is acceptable to return 1 if an indeterminant number

With the current implementation, we have:
* FIFO is full -> pending() returns 0
* FIFO is partially used -> pending() returns 1
* FIFO is empty -> pending() returns 1
This is not the same as what the documentation requires.
Moreover, since [1], arm reset now flushes all console devices
(including serial) before the cpu gets reset.
Because of the flawed logic:
=> reset # user calls reset
flush() is called
_serial_flush() is called
ops->pending(dev, false) # never returns false
# board hangs indefinitely without resetting.
Fix it by using AML_UART_TX_EMPTY instead of AML_UART_TX_FULL.

- cdns: Fix broken retry mechanism on arbitration lost
The ubifsload command is truncating any address above 4GiB as it casts
this address to an u32, instead of using an unsigned long which most of
the other load commands do. Change this to an unsigned long to allow
loading into high memory for boards which use these areas.
Fixes the following error:

In the current implementation, in case of I2C arbitration lost, a retry is
attempted; the message counter and pointer are reset to the original values
and the I2C xfer process is restart from the beginning.
However the message counter and message pointer are respectively
decremented and incremented by one before attempting any transfer, causing
the 1st transfer not to be actually retried (in case of a single transfer,
nothing is actually retried at all).
This patch fixes this: in case of retry, the 1st transfer is also retried.
Tested on a ZynqMP Kria board, with upstream older u-boot, but the involved
file and underlying logic seem basically the same.

K3 devices have some firewalls set up by ROM that we usually remove so
that the development is easy in HS devices.
While removing the firewalls disabling a background region before
disabling the foreground regions keeps the firewall in a state where all
the transactions will be blacklisted until all the regions are disabled.
This causes a race for some other entity trying to access that memory
region before all the firewalls are disabled and causes an exception.
Since there is no guarantee on where the background regions lie based on
ROM configurations or no guarantee if the background regions will allow
all transactions across the memory spaces, iterate the loop twice removing
the foregrounds first and then backgrounds.

As per [1], dfu_alt_info is mentioned to be as semicolon separated
string of information on each alternate and the parsing logic in
the dfu.c is based on this.
Typically, the dfu_alt_info_* is defined in .h files as preprocessor
macros with 'alt' info separated by semicolon.
But when dfu_alt_info_* is added in the environment files(.env)
the script at "scripts/env2string.awk" converts a newline to space.
Thus adding a space character after semicolon. This results in
incorrect parsing in dfu.c which is based on the information that
'alt' info are only semicolon separated.
One option is to add dfu_alt_info_* variable in .env in single line.
But there is possiblity for it to exceed the line length limit.
So update the parsing logic to remove leading space characters
before adding to the dfu list.

Currently, all in-tree .dts files (apart from some under test/ and
tools/), reside in arch/$ARCH/dts. However, in the linux kernel tree,
dts files for arm64 boards, and probably in the not too distant
future [1], arm boards as well, live in subdirectories of that.
For private forks, using a vendor or project subdirectory is also more
convenient to clearly separate private code from upstream - in the
same way that code under board/ is also split and easy to maintain.
In order to prepare for us to follow suit and do the splitting of the
in-tree .dts files, and to make life a little easier for private forks
that already place dts files not directly in arch/$ARCH/dts, change
the $(srctree)/arch/$(ARCH)/dts path to instead refer to the directory of
the .dts file being compiled. This should be a no-op for all existing
cases.
