d53b2cfe08 docs: fix wrong proftool usage
Guide shows incorrect usage of proftool, which is confusing. If proftool
is used w/o '-o' argument it complains like following

$ ./sandbox/tools/proftool -m sandbox/System.map -t trace dump-ftrace > trace.dat
Must provide trace data, System.map file and output file
Usage: proftool [-cmtv] <cmd> <profdata>

s/>/-o/ fixes it and proftool outputs decoded data to trace.dat

4d03f476a7 arm: mach-k3: Workaround errata ID i2331
Errata doc: https://www.ti.com/lit/pdf/sprz457
Errata ID i2331 CPSW: Device lockup when reading CPSW registers

Details: A device lockup can occur during the second read of any CPSW
subsystem register after any MAIN domain power on reset (POR). A MAIN
domain POR occurs using the hardware MCU_PORz signal, or via software
using CTRLMMR_RST_CTRL.SW_MAIN_POR or CTRLMMR_MCU_RST_CTRL.SW_MAIN_POR.
After these resets, the processor and internal bus structures may get
into a state which is only recoverable with full device reset using
MCU_PORz.
Due to this errata, Ethernet boot should not be used on this device.

Workaround(s): To avoid the lockup, a warm reset should be issued after
a MAIN domain POR and before any access to the CPSW registers. The warm
reset realigns internal clocks and prevents the lockup from happening.
Workaround above errata by calling do_reset() in case of cold boot in
order to trigger warm reset. This needs enabling SYSRESET driver in R5
SPL to enable TI SCI reset driver.

bcfb23ec7e pinctrl: mediatek: set R1/R0 in case pullen/pullsel succeeded
Commit dafe0fbfb0 ("pinctrl: mediatek: rewrite mtk_pinconf_set and
related functions") changed the logic deciding to set R0 and R1
registers for V1 devices.

Before:
	/* Also set PUPD/R0/R1 if the pin has them */
	err = mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_PUPD, !pullup);
	if (err != -EINVAL) {
		mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R0, r0);
		mtk_hw_set_value(dev, pin, PINCTRL_PIN_REG_R1, r1);
	}

After:
	/* try pupd_r1_r0 if pullen_pullsel return error */
	err = mtk_pinconf_bias_set_pullen_pullsel(dev, pin, disable, pullup,
						  val);
	if (err)
		return mtk_pinconf_bias_set_pupd_r1_r0(dev, pin, disable,
						       pullup, val);

Tracing mtk_pinconf_bias_set_pullen_pullsel shows that the function
always either returns 0 in case of success or -EINVAL in case any error
has occurred. Hence the logic responsible of the decision to program R0
and R1 has been inverted.

This leads to problems on BananaPi R2 (MT7623N) when booting from
SDMMC, it turns out accessing eMMC no longer works since
U-Boot 2022.07:

MT7623> mmc dev 0
Card did not respond to voltage select! : -110

The problem wasn't detected for a long time as both eMMC and SDMMC work
fine if they are used to boot from, and hence R0 and R1 were already
setup by the bootrom and/or preloader.

Fix the logic to restore the originally intended and correct behavior
and also change the descriptive comment accordingly.

28e5e95bf8 arm: mach-k3: am62a7: Enable QoS for DSS
Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by
servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is
done by setting the DSS DMA orderID to 8.

The C7x and VPAC have been overwhelming the DSS's access to the DDR
(when it was accessing via the Non Real-Time (NRT) Queue), primarily
because their functional frequencies, and hence DDR accesses, were
significantly higher than that of DSS. This led the display to flicker
when certain edgeAI models were being run.

With the DSS traffic serviced from the RT queue, the flickering issue
has been found to be mitigated.

The am62a qos files are auto generated from the k3 resource partitioning
tool.

Section-3.1.12, "QoS Programming Guide", in the AM62A TRM[1], provides
more information about the QoS, and section-14.1, "System Interconnect
Registers", provides the register descriptions.

b8ebf24e7f arm: mach-k3: common: don't reconfigure background firewalls
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 the background regions configured by ROM are in such a manner
that they allow all transactions, don't touch the background regions at
all.

Starting from QUP v2.5 the value of oversampling is changed from 32
to 16, keeping the old value on newer platforms results on wrong set
UART IP clock divider, thus the asked baudrate does not correspond to
the actually set with all the consequencies for a user.

The change links the driver to a new Qualcomm GENI SE QUP driver
to get its hardware version and update the oversampling value.

Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched,
since a wanted baudrate can be controlled by setting a modified
CONFIG_DEBUG_UART_CLOCK build time variable.

6f63c296fe board: Add new Broadcom Northstar board
This adds a simple Northstar "BRCMNS" board to be used with
the BCM4708x and BCM5301x chips.

The main intention is to use this with the D-Link DIR-890L
and DIR-885L routers for loading the kernel into RAM from
NAND memory using the BCH-1 ECC and using the separately
submitted SEAMA load command, so we are currently not adding
support for things such as networking.

The DTS file is a multiplatform NorthStar board, designed to
be usable with several NorthStar designs by avoiding any
particulars not related to the operation of U-Boot.

If other board need other ECC for example, they need to
create a separate DTS file and augment the code, but I don't
know if any other users will turn up.

d3d9cd8ee1 arm: Add support for the Broadcom Northstar SoCs
The original Northstar is an ARM SoC series that comprise
BCM4709x and BCM5301x and uses a dual-core Cortex A9, the
global timer and a few other things.

This series should not be confused with North Star Plus
(NSP) which is partly supported by U-Boot already.

The SoC is well supported by the Linux kernel and OpenWrt
as it is used in many routers.

Since we currently don't need any chip-specific quirks
and can get the system up from just the device tree, a
mach-* directory doesn't even need to be added, just
some small Kconfig fragments.

8a5122bfd3 arm: dts: Import device tree for Broadcom Northstar
This brings in the main SoC device tree used by the
Broadcom Northstar chipset, i.e. BCM4709x and BCM5301x.
This is taken from the v6.3 Linux kernel.
