This adds initial support for two SoC families that have been under
review for a while. In both cases, the origonal idea was to have a
minimally functional version, but we ended up leaving out the clk drivers
that are still under review and will be merged through the corresponding
subsystem tree.
The Nuvoton NPCM8xx is a 64-bit Baseboard Management Controller and
based on the 32-bit NPCM7xx family but is now getting added to
arch/arm64 as well.
Sunplus SP7021, also known as Plus1, is a general-purpose
System-in-Package design based on the 32-bit Cortex-A7 SoC
on the main chip, plus an I/O chip and memory in the same

This branch includes the usual updates to defconfig files, enabling
additional driver support for the supported platforms.
There is also a global refresh for all of them that reorders the
lines according to the 'savedefconfig' output, but without removing
lines that are no longer part of the refresh.
I went through the most common removed lines to also address them
while making sure to catch renamed options and add them back
under the new name.
The boardfile deprecation branch is based on top of this to avoid
conflicts against removing the unused boardfile configs from the
generic defconfig files.

As usual, the bulk of the changes for the SoC tree are devicetree file
updates, and most of these changes are for 64-bit embedded machines.
As before, there are a ton of style cleanups, and additional hardware
support for existing machines.
Looking only at the new SoC, the notable additions are:
- A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
Each SoC comes with a corresponding reference board.
- The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
i.MX8 embedded SoCs, now using Cortex-A55 cores and the
Ethos-U65 NPU.
- Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
of Arm based Laptop SoCs, and its automotive cousin, the
SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
laptop that also gets added here in addition to the reference
boards.
- Allwinner H616, a newer version of the H6 SoC, targeted at
Set-top-box applications. It comes with dts files for the
Orange Pi zero2 single-board computer and the X96 Mate
set-top-box
- Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip
in the Armada SoC family based on the Cortex-A55 core.
New machines based on previously supported SoCs include:
- Several new machines on NXP i.MX platforms: multiple Toradex
Colibri boards using the "Iris" and "Ixora" carriers,
DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems
TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM.
- Google Chameleon v3 FPGA board based on Intel Arria10 and
Stratix 10 Software Virtual platform, both in the SoCFPGA
platform.
- Two new wireless devices based on Broadcom SoCs:
The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point
- Improved Chromebook support for both the Mediatek and Qualcomm
SoC families brought added machines: Acer Chromebook 514 (MT8192),
Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based
machines including the Lenovo IdeaPad Chromebook Duet 3.
- Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
- Finally, there are a few development board on other chips:
PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308)
DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm
SDM660)

ARM: findbit: fix overflowing offset
ARM: 9216/1: Fix MAX_DMA_ADDRESS overflow
When offset is larger than the size of the bit array, we should not
attempt to access the array as we can perform an access beyond the
end of the array. Fix this by changing the pre-condition.
Using "cmp r2, r1; bhs ..." covers us for the size == 0 case, since
this will always take the branch when r1 is zero, irrespective of
the value of r2. This means we can fix this bug without adding any
additional code!

Commit 26f09e9b3a06 ("mm/memblock: add memblock memory allocation apis")
added a check to determine whether arm_dma_zone_size is exceeding the
amount of kernel virtual address space available between the upper 4GB
virtual address limit and PAGE_OFFSET in order to provide a suitable
definition of MAX_DMA_ADDRESS that should fit within the 32-bit virtual
address space. The quantity used for comparison was off by a missing
trailing 0, leading to MAX_DMA_ADDRESS to be overflowing a 32-bit
quantity.
This was caught thanks to CONFIG_DEBUG_VIRTUAL on the bcm2711 platform
where we define a dma_zone_size of 1GB and we have a PAGE_OFFSET value
of 0xc000_0000 (CONFIG_VMSPLIT_3G) leading to MAX_DMA_ADDRESS being
0x1_0000_0000 which overflows the unsigned long type used throughout
__pa() and then __virt_addr_valid(). Because the virtual address passed
to __virt_addr_valid() would now be 0, the function would loudly warn
and flood the kernel log, thus making the platform unable to boot
properly.

Let's make timer-ti-dm selectable for ARCH_K3, and add a separate option
for OMAP_DM_SYSTIMER as there should be no need for it on ARCH_K3.
For older TI SoCs, we are already selecting OMAP_DM_TIMER in
arch/arm/mach-omap*/Kconfig. For mach-omap2, we need to now also select
OMAP_DM_SYSTIMER.

Add basic support for pcb8309. It is similar with pcb8291 with one big
difference that is having 2 SFP cages. Therefore it has 4 network ports.

from this code, so declare them in the header file to avoid
the following sparse warnings:

Laurence reports:
"Kernel >5.18 on Zaurus has a bug where the power management code can't
talk to devices, emitting the following errors:
sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22.
sharpsl-pm sharpsl-pm: Charging Error!
sharpsl-pm sharpsl-pm: Warning: Cannot read main battery!
Looking at the recent changes, I found that commit 31455bbda208 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."
After reviewing the change I conclude that the same fix is needed
for all affected boards.

CONFIG_LEDS was replaced by CONFIG_NEW_LEDS over ten years ago with commit
fa8bbb13ab49 ("ARM: use new LEDS CPU trigger stub to replace old one"),
but some defconfig files still reference it.
Replace it and its sub-options with the corresponding new versions.
Some of these machines may not actually have a new-style LED driver,
and I did not check them individually as most of the machines are
going away soon anyway.

Since commit 1515b186c235 ("ARM: make configuration of userspace
Thumb support an expert option"), CONFIG_THUMB cannot be disabled
unless one turns on CONFIG_EXPERT first.
This is probably for the better, so remove the statements that
turn it off.

CONFIG_DEBUG_INFO is now implicitly selected if one picks one of the
explicit options that could be DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT,
DEBUG_INFO_DWARF4, DEBUG_INFO_DWARF5.
This was actually not what I had in mind when I suggested making
it a 'choice' statement, but it's too late to change again now,
and the Kconfig logic is more sensible in the new form.
Change any defconfig file that had CONFIG_DEBUG_INFO enabled
but did not pick DWARF4 or DWARF5 explicitly to now pick the toolchain
default.

The default is always 0x0 after commit 39c3e304567a ("ARM: 8984/1:
Kconfig: set default ZBOOT_ROM_TEXT/BSS value to 0x0"), so any
defconfig file that has these two lines can now drop them to reduce
the diff against the 'make savedefconfig' version.

A lot of Kconfig options have changed over the years, and we tend
to not do a blind 'make defconfig' to refresh the files, to ensure
we catch options that should not have gone away.
I used some a bit of scripting to only rework the bits where an
option moved around in any of the defconfig files, without also
dropping any of the other lines, to make it clearer which options
we no longer have.

This adds support for booting secondary cores, SPM, SMD-RPM and RPM
power-domain support for the MSM8909 platform.
It drops an unnecessary print in icc-bwmon, corrects SA8540P entries in
socinfo and a Kconfig build dependency for QCOM_RPMPD.
Lastly it continues to clean up up the Devicetree bindings for the
Qualcomm drivers.

When running under OP-TEE, the L2 cache is configured by OP-TEE and the
sam platform code does not allow any modification yet. Setup a dummy
.write_sec() callback to avoid triggering exceptions when Linux tries
to modify the L2 cache configuration.

Merge the new SoC support from Tomer Maimon:
"This patchset adds initial support for the Nuvoton
Arbel NPCM8XX Board Management controller (BMC) SoC family.
The Nuvoton Arbel NPCM8XX SoC is a fourth-generation BMC.
The NPCM8XX computing subsystem comprises a quadcore ARM
Cortex A35 ARM-V8 architecture.
This patchset adds minimal architecture and drivers such as:
Clocksource, Clock, Reset, and WD.
Some of the Arbel NPCM8XX peripherals are based on Poleg NPCM7XX.
This patchset was tested on the Arbel NPCM8XX evaluation board."
I'm leaving out the clk controller driver, which is still under
review.

The LED controller node is disabled because the leds-turris-omnia driver
does not support setting the LED blinking to be controlled by the MCU.
The patches for that have now been sent [1], so let's enable the node.

The marvell PHY driver changes the LED[0] pin function to "On - 1000
Mbps Link, Off - Else".
Turris Omnia expects that the function is "On - Link, Blink - Activity,
Off - No link".
Use the `marvell,reg-init` DT property to change the function.
In the future, once netdev trigger will support HW offloading, we will
be able to have this configured via the combination of PHY driver and
leds-turris-omnia driver.

- The code relies on rc_pci_fixup being called, which only happens
when CONFIG_PCI_QUIRKS is enabled, so add that to Kconfig. Omitting
this causes a booting failure with a non-obvious cause.
- Update rc_pci_fixup to set the class properly, copying the
more modern style from other places
- Correct the rc_pci_fixup comment
This patch just re-applies commit 1dc831bf53fd ("ARM: Kirkwood: Update
PCI-E fixup") for all other Marvell ARM platforms which have same buggy
PCIe controller and do not use pci-mvebu.c controller driver yet.
Long-term goal for these Marvell ARM platforms should be conversion to
pci-mvebu.c controller driver and removal of these fixups in arch code.

The sys_clk frequency is 165.625MHz. The register reference of the
Generic Clock controller lists the CPU clock as 600MHz, the DDR clock as
300MHz and the SYS clock as 162.5MHz. This is wrong. It was first
noticed during the fan driver development and it was measured and
verified via the CLK_MON output of the SoC which can be configured to
output sys_clk/64.
The core PLL settings (which drives the SYS clock) seems to be as
follows:
DIVF = 52
DIVQ = 3
DIVR = 1
With a refernce clock of 25MHz, this means we have a post divider clock
Fpfd = Fref / (DIVR + 1) = 25MHz / (1 + 1) = 12.5MHz
The resulting VCO frequency is then
Fvco = Fpfd * (DIVF + 1) * 2 = 12.5MHz * (52 + 1) * 2 = 1325MHz
And the output frequency is
Fout = Fvco / 2^DIVQ = 1325MHz / 2^3 = 165.625Mhz
This all adds up to the constrains of the PLL:
10MHz <= Fpfd <= 200MHz
20MHz <= Fout <= 1000MHz
1000MHz <= Fvco <= 2000MHz

The remoteproc configuration in qcom-msm8974.dtsi is incomplete because
it lacks the regulator supplies that should be added in the board DT
files. Some of the msm8974 boards are currently missing the regulator
supplies and should have the remoteprocs disabled to avoid making use
of the incomplete configuration.
This also fixes dtbs_check warnings after moving "qcom,msm8974-mss-pil"
to DT schema, which rightfully complains that the -supply properties
are missing for some boards:
