3c8ee337eb arm64: zynqmp: Add reset-on-timeout for all boards and modify default timeout value
This patch adds reset-on-timeout to FPD WDT which will trigger an
interrupt to PMU when watchdog expiry happens and PMU takes the
necessary action. If this property is not enabled, reason will not be
known when watchdog expiry happens.
This patch also modifies the default timeout to 60 seconds. Reason is
that if u-boot enables WDT, it will set the timeout to 10 seconds and
this is not enough to boot till Linux and start the WDT application in
Linux. 60 seconds is the maximum safest value to boot till Linux and
start the WDT application.

Users need to change this timeout value to fit their needs.

24124abe06 arm64: zynqmp: Add support for generic QSPI boot
This patch is enabling support for SPL QSPI boot.

First of all it is necessary to generate atf-spi.ub which is different
format than atf-uboot.ub (this can be made as legacy image too)

ADDR=`arm-xilinx-linux-gnueabi-readelf -a bl31.elf | grep "Entry point
address" | cut -d ':' -f 2 | sed -e 's/^[ \t]*//'`
aarch64-linux-gnu-objcopy -O binary bl31.elf bl31.bin
./tools/mkimage -f auto -A arm64 -T firmware -C none -O u-boot -a $ADDR
-e $ADDR -n "atf1" -E -b arch/arm/dts/zynqmp-zcu102.dtb -d bl31.bin
atf-uboot.ub
./tools/mkimage -A arm64 -T firmware -C none -O u-boot -a $ADDR -e $ADDR
-n "atf-for-qspi" -E -d bl31.bin atf-spi.ub

This patch is using this QSPI layout with offsets:
0 boot.bin
512k atf-ub
640k u-boot.bin
1280k u-boot.img

Which corresponding by writing these images(read from MMC)
mmcinfo
sf probe
load mmc 0 10000000 boot.bin
sf erase 0 +$filesize
sf write 10000000 0 $filesize
load mmc 0 10000000 atf-spi.ub
sf erase 0x80000 +$filesize
sf write 10000000 0x80000 $filesize
load mmc 0 10000000 u-boot.bin
sf erase 0xa0000 +$filesize
sf write 10000000 0xa0000 $filesize
load mmc 0 10000000 u-boot.img
sf erase 0x140000 +$filesize
sf write 10000000 0x140000 $filesize

For testing u-boot running in EL3 you can break atf-spi.ub like this:
sf probe
sf erase 0x80000 +4

Then u-boot.img is executed.

110d06b2e3 arm64: zynqmp: Add SMMU support for SATA IP
AXI master interface in CEVA AHCI controller requires two unique
Write/Read ID tags per port. This is because, ahci controller uses
different AXI ID[3:0] bits for identifying non-data transfers(like
reading descriptors, updating PRD tables, etc) and data transfers
(like sending/receiving FIS).To make SMMU work with SATA we need to
add correct SMMU stream id for SATA. SMMU stream id for SATA is
determined based on the AXI ID[1:0] as shown below

	SATA SMMU ID =  <TBU number>, 0011, 00, 00, AXI ID[1:0]
	Note: SATA in  ZynqMp uses TBU1 so TBU number = 0x1, so
	      SMMU ID = 001, 0011, 00, 00, AXI ID[1:0]

Since we have four different AXI ID[3:0] (2 for port0 & 2 for port1
as said above) we get four different SMMU stream id's combinations
for SATA. These AXI ID can be configured using PAXIC register.
In this patch we assumed the below AXI ID values

 Read ID/ Write ID for Non-Data Port0 transfers = 0
 Read ID/ Write ID for Data Port0 transfers = 1
 Read ID/ Write ID for Non-Data Port1 transfers = 2
 Read ID/ Write ID for Data Port1 transfers = 3

Based on the above values,SMMU stream ID's for SATA will be 0x4c0 &
0x4c1 for PORT0, 0x4c2 & 0x4c3 for PORT1. These values needed to be
added to iommus dts property. This patch does the same.

6db82e0956 arm64: zynqmp: Fix broken architected timer interrupt trigger
Extract from Linux mainline patch:
The ARM architected timer specification mandates that the interrupt
associated with each timer is level triggered (which corresponds to
the "counter >= comparator" condition).

A number of DTs are being remarkably creative, declaring the interrupt
to be edge triggered. A quick look at the TRM for the corresponding ARM
CPUs clearly shows that this is wrong, and I've corrected those.
For non-ARM designs (and in the absence of a publicly available TRM),
I've made them active low as well, which can't be completely wrong
as the GIC cannot disinguish between level low and level high.

The respective maintainers are of course welcome to prove me wrong.

While I was at it, I took the liberty to fix a couple of related issue,
such as some spurious affinity bits on ThunderX, and their complete
absence on ls1043a (both of which seem to be related to copy-pasting
from other DTs).

Changed min-residence to 10ms(was 100 ms) for cpu-sleep-0.
Tried lower values 5ms and 8ms and it worked fine with Debug Off.
But to accommodate PM Debug On case, 10 ms is required. With this
change, low power idle state is into effect more frequently.
Measured boot time with PM debugs On and Off. No change observed
compared to 100ms value.
