As of now only one mailbox agent is supported by mailbox driver.
On zynqmp platform there are about 7 mailbox agents which can communicate
over same IPI channel to U-Boot. This patch series introduces new
"zynqmp_ipi_dest" driver which adds one to multi-channel mailbox
support.
Following format in device-tree is expected as per latest bindings:
zynqmp-ipi {
compatible = "xlnx,zynqmp-ipi-mailbox";
mbox_1: mailbox@1 {
/* New compatible for child node */
compatible = "xlnx,zynqmp-ipi-dest-mailbox";
...
};
...
mbox_n: mailbox@n {
compatible = "xlnx,zynqmp-ipi-dest-mailbox";
...
}
};
Then mailbox client uses child mailbox node as following:
ipi-dest-1 {
...
mboxes = <mbox_1 0>, <mbox_1 1>;
mbox-names = "tx", "rx";
...
};
New "zynqmp_ipi_dest" driver is for devices with
"xlnx,zynqmp-ipi-dest-mailbox" compatible string. This driver will take care
of mailbox send recv ops and it replaces previous "zynqmp_ipi" driver.
Now "zynqmp_ipi" driver simply binds each child device with "zynqmp_ipi_dest"
driver.
However, its important to maintain backward comaptibility with previous
bindings where child node does not have compatible string. In such case, new
driver isn't probed by U-Boot during boot and system fails to boot. To
resolve this issue firmware-zynqmp.c driver probes all the IPI parent node
driver which binds each child node device with "zynqmp_ipi_dest" driver.
This makes sure corresponding child driver will be
probed when requested using mbox_get_by_name or mbox_get_by_idx
framework calls.
This way multiple mailbox agents are supported in device-tree without breaking
previous binding support.

In case of A/B update systems there should be an option to load the same
binary/binaries to different location and they should work.
Before this patch boot.bin with U-Boot SPL can be added to whatever 32k
offset in SPI and SPL finds u-boot.itb at CONFIG_SYS_SPI_U_BOOT_OFFS
offset. In case of A/B update systems that means that SPL is at different
locations but it still points to the same u-boot.itb which is not correct.
That's why include multiboot value to offset calculation to be able to
point to image from the same base.
It doesn't affect any current system which starts from 0 offset.
This patch also change Kria defconfig which uses A/B setup. Partition
A starts at multiboot 64, partition B at multiboot 496.
And also print message about used SPI offset which is useful for all cases.

- Add PCI fixup for GW73xx-F+
- Fix broken EEPROM read on imx8mn-var-som
Later versions of Colibri iMX7D V1.1B modules use a "new" SoC fusing. The
difference lies in whether we enable the boot ROM to use the eMMC reset
signal. Depending on the SoC fuse, the boot ROM configures this pin as a
GPIO output to drive the reset signal. Our eMMC vs NAND detection
currently only sets that signal to a GPIO without explicitly setting any
direction. Previously, by default, it was set as an input. As the boot ROM
now configures it as an output, we receive a value of zero instead of one,
indicating the absence of the pull-up on eMMC modules.
To fix this, set the SION bit, allowing the reading back of the value
even if it is configured as an output by the boot ROM. It's important to
note that with the new SoC fusing, we now read back what the boot ROM
drives rather than the real value caused by the pull-up resistor. However,
if it were ever driven low, the eMMC would permanently be reset.
In addition, remove hard-coded variant in the eMMC build case as since the
commit 0c39564d02 ("toradex: colibri_imx7: Enable nand/emmc detection
and set boot variant") will anyways always get overridden by the detection
routing in board code.

Initially investigating a Linux network issue causing a lot of drop and
poor network performances on a custom system based on a TQMA6A module
(based on an iMX6Q), [1st link below].
I eventually correlated my observations with a contention at the NIC
level when in concurrency with the graphics pipeline. Troubleshooting
this in the kernel lead to disabling DMA bursts accesses made by the IPU
in order to avoid triggering the QoS at the interconnect level, reducing
from 50 to 10% the drop rate on eth0, [2nd link below]. The solution
worked on my setup but not on others, which still suffered from
abnormally high drop rates even with this "fix".
After looking a while into TQ Systems BSP I figured out a number of
differences in recent U-Boot out-of-tree patches they had in their
repository [3rd link]. Parsing the differences one after the other lead
me to this final solution.
The reset pad of the DDR controller was apparently misconfigured, Bit
18-19 picturing the "DDR select field". The current value b11 is
reserved. The only defined value as of version 6 of the iMX6Q manual was
b00 "DDR3 and LPDDR2 mode". In practice no register difference has been
spotted after changing this configuration but all issues tracked thus
far just vanished. All previous fixes have been proven irrelevant. Just
clearing this field solved all our network issues and the drop rate as
measured by iperf3 felt back to 0%.

USB host interface is not working on some Apalis Toradex carrier
boards with Apalis iMX8 SoM. This is due to USBH_EN pin, which
powers USB peripherals, having a strong pull-down on some boards,
and a weak pull-down on the others. This USBH_EN pin is left
unconfigured, which means it is in its default state at cold boot:
input with a strong pull-up. As a result, carrier boards with a
weak pull-down have this signal high enough to trigger power
delivery to USB peripherals, and opposite - boards with strong
pull-down on USBH_EN have this signal below the threshold needed
to trigger USB power delivery.
This change configures the USBH_EN pin as gpio hog, fixing this
issue for all Apalis carrier boards regardless of pull-down
resistor value.
Also, update apalis-imx8_defconfig via savedefconfig.
