Add support for the Nuvoton NPCM7xx SoC EDAC driver
NPCM7xx ECC datasheet from nuvoton.israel-Poleg:
"Cadence DDR Controller User’s Manual For DDR3 & DDR4 Memories"
Tested: Forcing an ECC error event
Write a value to the xor_check_bits parameter that will trigger
an ECC event once that word is read
For example, to force a single-bit correctable error on bit 0 of
the user-word space shown, write 0x75 into that byte of the
xor_check_bits parameter and then assert fwc (force write check)
bit to 'b1' (mem base: 0xf0824000, xor_check_bits reg addr: 0x178)
$ devmem 0xf0824178 32 0x7501
To force a double-bit un-correctable error for the user-word space,
write 0x03 into that byte of the xor_check_bits parameter
$ devmem 0xf0824178 32 0x301

For security reasons, some configuration needs to run without /dev/mem
but on some occasions, to debug HW for instance, it's still useful to
be able to reboot the system with access to physical memory.
Add a kernel parameter which activates the /dev/mem device only when
'mem.devmem' is enabled.

The ASPEED BMC SoCs have many knobs and switches that are sometimes
design-specific and often defy any approach to unify them under an
existing subsystem.
Add a driver to translate a devicetree table into sysfs entries to
expose bits and fields for manipulation from userspace. This encompasses
concepts from scratch registers to boolean conditions to enable or
disable host interface features.

Work around the shonky behaviour seen with the MAX31785 where we fail
to set the page register in some circumstances.
There's no real elegant way to do this. We can propagate the error up,
but that forces us to retry the operation way up the call tree in any
number of places. It also forces callers to split out pmbus_set_page()
from the pmbus_{read,write}_{byte,word}_data() functions in order to
differentiate between a failure to set the page and a failure to read a
register (that might not exist, in which case an error is anticiptated).

The driver may have overridden the pmbus_read_byte_data() callback, so
make sure we use that to achieve expected behaviour.
This helps in the MAX31785 case where we may need to perform a one-shot
retry of transfers in the face of a failure.

Currently in driver spi-nor there is a line for mx66l51235l.
According to Macronix site there is no such part number.
The chip detected as such is actually mx66l51235f.
According to the datasheet for mx66l51235f,
"The device default is in 24-bit address mode" (section 9-10).
Hence we removed SPI_NOR_4B_OPCODES option with this commit.

The training consists of finding the appropriate read timing delays for
the HCLK dividers 2, 3, 4, and 5 and store the results in the Read Timing
Compensation register. The previous SoC AST2500 and AST2400 were covering
a broader HCLK range [ 1 - 5 ] because the AHB frequency was lower.
The algorithm first reads a golden buffer at low speed and then performs reads
with different clocks and delay cycles settings to find a breaking point.
This selects the default clock frequency for the CEx control register.
The current settings are bit optimistic as we pick the first delay giving
good results. A safer approach would be to determine an interval and
choose the middle value. We might change the approach depending on the
results on other systems.
Only CS0 is taken into account for the moment.

The optimize read algo can choose a 100MHz SPI frequency which might
be a bit too high for dual output IO on some chips, for the W25Q256 on
palmetto for instance. The MX66L1G45G on witherspoon should be fine
though. Also, the second chip of the FMC controller does not get any
optimize settings for reads. Only the first is configured by U-Boot.
To fix these two issues, we introduce a "spi-max-frequency" property
in the device tree which will be used to cap the optimize read
algorithm and we run the algo on the FMC controller chips as well.
By default, the frequency setting is 50MHz.

The algo is based on the one found in the OpenPOWER pflash tool. It
first reads a golden buffer at low speed and then performs reads with
different clocks and delay cycles settings to find the fastest
configuration for the chip.
It can be deactivated at boot time with the kernel parameter :

commit dc5bdb68b5b369d5bc7d1de96fa64cc1737a6320 upstream.
In the past we had a pile of hacks to orchestrate access between fbdev
emulation and native kms clients. We've tried to streamline this, by
always preferring the kms side above fbdev calls when a drm master
exists, because drm master controls access to the display resources.
Unfortunately this breaks existing userspace, specifically Xorg. When
exiting Xorg first restores the console to text mode using the KDSET
ioctl on the vt. This does nothing, because a drm master is still
around. Then it drops the drm master status, which again does nothing,
because logind is keeping additional drm fd open to be able to
orchestrate vt switches. In the past this is the point where fbdev was
restored, as part of the ->lastclose hook on the drm side.
Now to fix this regression we don't want to go back to letting fbdev
restore things whenever it feels like, or to the pile of hacks we've
had before. Instead try and go with a minimal exception to make the
KDSET case work again, and nothing else.
This means that if userspace does a KDSET call when switching between
graphical compositors, there will be some flickering with fbcon
showing up for a bit. But a) that's not a regression and b) userspace
can fix it by improving the vt switching dance - logind should have
all the information it needs.
While pondering all this I'm also wondering wheter we should have a
SWITCH_MASTER ioctl to allow race-free master status handover. But
that's for another day.
v2: Somehow forgot to cc all the fbdev people.
v3: Fix typo Alex spotted.

commit b5b78a6c8d8cb9c307bc6b16a754603424459d6e upstream.
The function kobject_init_and_add alloc memory like:
kobject_init_and_add->kobject_add_varg->kobject_set_name_vargs
->kvasprintf_const->kstrdup_const->kstrdup->kmalloc_track_caller
->kmalloc_slab, in err branch this memory not free. If use
kmemleak, this path maybe catched.
These changes are to add kobject_put in kobject_init_and_add
failed branch, fix potential memleak.

commit 5ae9c378c3d88b40af72f8e8f961808e29f3e70b upstream.
[Why]
Connector property output_bpc is available on DP/eDP only. New IGT tests
would benifit if this property works on HDMI.
[How]
Enable this read-only property on all types of connectors.

commit 75b0cea7bf307f362057cc778efe89af4c615354 upstream.
Like other vectors already patched, this one here allows the root
user to load ACPI tables, which enables arbitrary physical address
writes, which in turn makes it possible to disable lockdown.
Prevents this by checking the lockdown status before allowing a new
ACPI table to be installed. The link in the trailer shows a PoC of
how this might be used.
