4b56446002 rockchip: px30: make watchdog and tsadc trigger a first global reset
By default, the PX30 is configured for watchdog and tsadc to trigger a
second global reset which is a more permissive reset than first global
reset.

From TRM part 1 "2.3 System Reset Solution":
glb_srstn_1 will reset the all logic, and
glb_srstn_2 will reset the all logic except GRF, SGRF and all GPIOs.

This enforces that the watchdog and tsadc trigger glb_srstn_1 as
similarly done for RK3399 in U-Boot (in SDRAM driver for some reason?),
TF-A and Coreboot.

2383e8f4ae usb: gadget: dwc2_udc_otg: implement pullup()
Pullup is used by the usb framework in order to do software-controlled
usb_gadget_connect() and usb_gadget_disconnect().

Implement pullup() for dwc2 using the SOFT_DISCONNECT bit in the dctl
register:
* when pullup is on, clear SOFT_DISCONNECT
* when pullup is off, set SOFT_DISCONNECT

This is especially useful when a gadget disconnection is initiated but
no board_usb_cleanup() is called.

66b5847b30 usb: gadget: fastboot: detach usb just before rebooting
The patch fixes the following error when updating a BSH SMM S2 board:
3:72>Start Cmd:FB[-t 8000]: ucmd nand write ${loadaddr} nanddtb ${filesize}
3:72>Okay (0.023s)
3:72>Start Cmd:FB: reboot
3:72>Fail Bulk(R):LIBUSB_ERROR_IO(0s)

The "fastboot reboot" command detaches the USB when it still needs to be
used. So let's detach the USB just before the reset.

5454dea313 usb: hub: allow to increase HUB_DEBOUNCE_TIMEOUT
Add a new CONFIG_USB_HUB_DEBOUNCE_TIMEOUT to increase the
HUB_DEBOUNCE_TIMEOUT value, for example to 2s because some usb device
needs around 1.5s or more to make the hub port status to be
connected steadily after being powered off and powered on.

This 2s value is aligned with Linux driver and avoids to configure
"usb_pgood_delay" as a workaround for connection timeout on
some USB device; normally the env variable "usb_pgood_delay" is used
to delay the first query after power ON and thus the device answer,
but this variable not used to increase the connection timeout delay.

87c9e117bf Merge branch '2023-01-12-further-assorted-general-updates'
- Bring in a number of assorted updates, some of which have been waiting
  around for a bit.  Make silent console really be silent, get rid of
  gpio_hog_probe_all, add RNG for imx6, make net/fm use fs_loader, get
  rid of a bad __weak usage and set distro_bootpart_uuid in another case.

48b3ecbedf gpio: Get rid of gpio_hog_probe_all()
The gpio_hog_probe_all() functionality can be perfectly well replaced by
DM_FLAG_PROBE_AFTER_BIND DM flag, which would trigger .probe() callback
of each GPIO hog driver instance after .bind() and thus configure the
hogged GPIO accordingly.

942918f2ac dm: fix probing of all devices that have u-boot, dm-pre-reloc in SPL/TPL
Currently, dm_probe_devices checks that the flags of the device contains
DM_FLAG_PRE_RELOC. However DM_FLAG_PRE_RELOC is a driver - and not a
device - flag. This means that the check in pre_reloc_only mode would
always fail.

Instead, what was aimed to be checked is that either the driver of the
device has the flag set, or that the device has the u-boot,dm-pre-reloc
Device Tree property set.

So let's fix the check to allow u-boot,dm-pre-reloc devices to be
probed.

d0ba0ca45a distro_bootcmd: Set distro_bootpart_uuid for block devices
The assignment of block device nodes in Linux is not deterministic by
default, i.e. a newly added eMMC controller or other block device can
change the assignment of /dev/mmcblkN (or other block device node like
e.g. /dev/sdXy) and prevent the system from picking the correct block
device for root filesystem in case the root filesystem is specified on
kernel command line using 'root=/dev/mmcblkNpM' (or 'root=/dev/sdXy'
etc.).

One way out is to derive PARTUUID in U-Boot, which is unique identifier
of a partition, and pass that as root=PARTUUID=<partuuid> to Linux via
kernel command line. Linux would then find the partition using PARTUUID,
no matter on which block device the partition resides and which node was
assigned to that block device.

Derive the PARTUUID before scanning for extlinux presence and assign it
into distro_bootpart_uuid environment variable, which can then be used
in extlinux.conf kernel command line specifier.

Note that it is not possible to do this in scan_dev_for_extlinux script
because this script is called from scan_dev_for_boot script, which is
called for both block devices as well as UBI volumes, and we can not
derive PARTUUID for UBI volumes.

ea3d28ec31 Revert "time: add weak annotation to timer_read_counter declaration"
This reverts commit 65ba7add0d.

A weak extern is a nasty sight to behold: If the symbol is never
defined, on ARM, the linker will replace the function call with a NOP.
This behavior isn't well documented but there are at least some hints
to it [1].

When timer_read_counter() is not defined, this obviously does the wrong
thing here and it does so silently.  The consequence is that a board
without timer_read_counter() will sleep for random amounts and generally
have erratic get_ticks() values.

Drop the __weak annotation of the extern so a linker error is raised
when timer_read_counter() is not defined.  This is okay, the original
reason for the reverted change - breaking the sandbox build - no longer
applies.

Final sidenote:  This was the only weak extern in the entire tree at
this time as far as I can tell.  I guess we should avoid introduction of
them again as they are obviously a very big footgun.

e4f0cc5ddf net: fm: Add firmware name parameter
In order to read the firmware from the filesystem, we need a file name.
Read the firmware name from the device tree, using the firmware-name
property. This property is commonly used in Linux to determine the
correct name to use (and can be seen in several device trees in U-Boot).
