b7a0ad16f9 misc: add PolarFire SoC system controller
This driver provides an interface to access the functions of the system
controller on the Microchip PolarFire SoC.
This driver includes functions to use the system controller to read
the device serial number.

896f570d56 Merge patch series "Add support for K3 BIST"
Neha Malcom Francis <n-francis@ti.com> says:

This series implements a driver for the BIST (Built-In Self Test) module
for K3 devices. The BIST driver must ideally support triggering of BIST
tests, both PBIST (Memory BIST) and LBIST (Logic BIST) on a core. Both
tests are destructive in nature. Please see links [1] and [2] for
further information regarding the two.

At boot up, BIST is executed by hardware for the MCU domain
automatically as part of HW POST. So BIST has been checked only for the
MCU domain when U-Boot comes up in the usual U-Boot to Linux boot flow.
To facilitate the use-case where some safe firmware is intended to be
run on a safe core, it is best to have triggered the BIST tests on that
core. As an example, we take triggering the BIST tests on the MAIN R52_x
cores. The triggering patch is kept as DONOTMERGE.

The general procedure for triggering BIST on a core is:
	1. Power on the core under test following a sequence
	2. Trigger the BIST test
	3. Reset the core under test following a sequence

BIST tests are triggered from A72 SPL where the DM (Device Manager
firmware that handles power management) is already up and can perform
these power sequences for us.

Boot logs (with LOG_DEBUG and CONFIG_K3_BIST enabled) and DT node kept (already
merged to ti-k3-dts-next [3]):

commit 1b15483deb3f ("misc: add Qualcomm GENI SE QUP device driver")
introduced support for platform-specific oversampling values, necessary
to configure the UART clocks on all platforms at runtime. However it
relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag,
this is not done consistently during boot.

Instead, take another approach by relying on ofnode_ helpers to read the
serial engine base address and do the read directly. This fixes early
UART on boards with a non-default oversampling rate.

2645bc0e12 arm: layerscape: Add sfp driver
This adds a driver for the Security Fuse Processor (SFP) present on
LS1012A, LS1021A, LS1043A, and LS1046A processors. It holds the
Super-Root Key (SRK), One-Time-Programmable Master Key (OTPMK), and
other "security" related fuses. Similar devices (sharing the same name)
are present on other processors, but for the moment this just supports
the LS2 variants.

The mirror registers are loaded during power-on reset. All mirror
registers must be programmed or read at once. Because of this, `fuse
prog` will program all fuses, even though only one might be specified.
To prevent accidentally burning through all your fuse programming cycles
with something like `fuse prog 0 0 A B C D`, we limit ourselves to one
programming cycle per reset. Fuses are numbered based on their address.
The fuse at 0x1e80200 is 0, the fuse at 0x1e80204 is 1, etc.

The TA_PROG_SFP supply must be enabled when programming fuses, but must
be disabled when reading them. Typically this supply is enabled by
inserting a jumper or by setting a register in the board's FPGA. I've
also added support for using a regulator. This could be helpful for
automatically issuing the FPGA write, or for toggling a GPIO controlling
the supply.

I suggest using the following procedure for programming:

1. Override the fuses you wish to program
   => fuse override 0 2 A B C D
2. Inspect the values and ensure that they are what you expect
   => fuse sense 0 2 4
3. Enable TA_PROG_SFP
4. Issue a program command using OSPR0 as a dummy. Since it contains the
   write-protect bit you will usually want to write it last anyway.
   => fuse prog 0 0 0
5. Disable TA_PROG_SFP
6. Read back the fuses and ensure they are correct
   => fuse read 0 2 4

c8ce7ba87d misc: Add support for nvmem cells
This adds support for "nvmem cells" as seen in Linux. The nvmem device
class in Linux is used for various assorted ROMs and EEPROMs. In this
sense, it is similar to UCLASS_MISC, but also includes
UCLASS_I2C_EEPROM, UCLASS_RTC, and UCLASS_MTD. New drivers corresponding
to a Linux-style nvmem device should be implemented as one of the
previously-mentioned uclasses. The nvmem API acts as a compatibility
layer to adapt the (slightly different) APIs of these uclasses. It also
handles the lookup of nvmem cells.

While nvmem devices can be accessed directly, they are most often used
by reading/writing contiguous values called "cells". Cells typically
hold information like calibration, versions, or configuration (such as
mac addresses).

nvmem devices can specify "cells" in their device tree:

	qfprom: eeprom@700000 {
		#address-cells = <1>;
		#size-cells = <1>;
		reg = <0x00700000 0x100000>;

		/* ... */

		tsens_calibration: calib@404 {
			reg = <0x404 0x10>;
		};
	};

which can then be referenced like:

	tsens {
		/* ... */
		nvmem-cells = <&tsens_calibration>;
		nvmem-cell-names = "calibration";
	};

The tsens driver could then read the calibration value like:

	struct nvmem_cell cal_cell;
	u8 cal[16];
	nvmem_cell_get_by_name(dev, "calibration", &cal_cell);
	nvmem_cell_read(&cal_cell, cal, sizeof(cal));

Because nvmem devices are not all of the same uclass, supported uclasses
must register a nvmem_interface struct. This allows CONFIG_NVMEM to be
enabled without depending on specific uclasses. At the moment,
nvmem_interface is very bare-bones, and assumes that no initialization
is necessary. However, this could be amended in the future.

Although I2C_EEPROM and MISC are quite similar (and could likely be
unified), they present different read/write function signatures. To
abstract over this, NVMEM uses the same read/write signature as Linux.
In particular, short read/writes are not allowed, which is allowed by
MISC.

The functionality implemented by nvmem cells is very similar to that
provided by i2c_eeprom_partition. "fixed-partition"s for eeproms does
not seem to have made its way into Linux or into any device tree other
than sandbox. It is possible that with the introduction of this API it
would be possible to remove it.

467f0c4dc2 misc: atsha204a: Remove duplicate CRC-16 implementation
ATSHA204A uses bit-reversed checksum of standard CRC-16 with polynomial
x^16 + x^15 + x^2 + 1.

This ATSHA204A specific checksum can be calculated just by using common
U-Boot functions bitrev16() and crc16().

So replace custom driver CRC-16 implementation by common U-Boot functions.

Switch the default to hex (0x0) and remove the defconfigs that were
using the default, but as hex before.
