930a3ddade dm: core: Support accessing core tags
At present tag numbers are only allocated for non-core data, meaning that
the 'core' data, like priv and plat, are accessed through dedicated
functions.

For debugging and consistency it is convenient to use tags for this 'core'
data too. Add support for this, with new tag numbers and functions to
access the pointer and size for each.

Update one of the test drivers so that the uclass-private data can be
tested here.

There is some code duplication with functions like device_alloc_priv() but
this is not addressed for now. At some point, some rationalisation may
help to reduce code size, but more thought it needed on that.

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.

532a5b297c misc: atsha204a: fix i2c address readout from DTS
This patch replaces use fdtdec_get_addr with simpler dev_read_addr().
fdtdec_get_addr doesn't work properly on ZynqMP-based (64bit) system. Although
not confirmed, it could be related to the fact, that quoting the documentation,
"This variant hard-codes the number of cells used to represent the address and
size based on sizeof(fdt_addr_t) and sizeof(fdt_size_t)".

Fix a regression brings by commit 84f8e36f03 ("cmd: bind: allow to
bind driver with driver data")

As example, the following bind command doesn't work:

   bind /soc/usb-otg@49000000 usb_ether

As usb_ether driver has no compatible string, it can't be find by
lists_bind_fdt(). In bind_by_node_path(), which called lists_bind_fdt(),
the driver entry is known, pass it to lists_bind_fdt() to force the driver
entry selection.

For this, add a new parameter struct *driver to lists_bind_fdt().
Fix also all lists_bind_fdt() callers.

e712245d08 sandbox: cros-ec: Add tests for the Chromium OS EC PWM driver
This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple
channels but can only set a duty cycle for each, as the actual EC
doesn't expose any functionality or information other than that. Though
the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.

This emulated PWM device is then used to test the Chromium OS PWM driver
in sandbox. Adding the required device node to the sandbox test
device-tree unfortunately makes it the first PWM device, so this also
touches some other tests to make sure they still use the sandbox PWM.

5b0b43e0e2 x86: qemu: move QFW to its own uclass
We move qfw into its own uclass and split the PIO functions into a
specific driver for that uclass.  The PIO driver is selected in the
qemu-x86 board config (this covers x86 and x86_64).

include/qfw.h is cleaned up and documentation added.

1b9ee2882e pwm: Add a driver for Chrome OS EC PWM
This PWM is used in rk3399-gru-bob and rk3399-gru-kevin to control
the display brightness. We can only change the duty cycle, so on
set_config() we just try to match the duty cycle that dividing duty_ns
by period_ns gives us. To disable, we set the duty cycle to zero while
keeping the old value for when we want to re-enable it.

The cros_ec_set_pwm_duty() function is taken from Depthcharge's
cros_ec_set_bl_pwm_duty() but modified to use the generic pwm type.
The driver itself is very loosely based on rk_pwm.c for the general pwm
driver structure.

The devicetree binding file is from Linux, before it was converted to
YAML at 5df5a577a6b4 ("dt-bindings: pwm: Convert google,cros-ec-pwm.txt
to YAML format") in their repo.

cc469b7086 dm: Rename device_get_by_driver_info_idx()
This function finds a device by its driver_info index. With
of-platdata-inst we do not use driver_info, but instead instantiate
udevice records at build-time.

However the semantics of using the function are the same in each case:
the caller provides an index and gets back a device.

So rename the function to device_get_by_ofplat_idx(), so that it can be
used for both situations. The caller does not really need to worry about
the details.

d1f3abe1e7 dm: i2c: allow disabling driver model in SPL
At present if U-Boot proper uses driver model for I2C, then SPL has to
also. While this is desirable, it places a significant barrier to moving
to driver model in some cases. For example, with a space-constrained SPL
it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves
adjusting some drivers.

This patch introduces a separate Kconfig symbols for enabling DM_I2C and
DM_I2C_GPIO support in SPL.

This will also help to get away from dirty workarounds to
achieve non-DM I2C support for SPL, which is currently used in some
board header files like:

ifdef CONFIG_SPL_BUILD
undef CONFIG_DM_I2C
endif

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.
