The _REC suffix doesn't add much. Really what we want to know is whether

725c438c62 test: Rename unit-test flags
The UT_TESTF_ macros read as 'unit test test flags' which is not right.
Rename to UTF ('unit test flags').

This has the benefit of being shorter, which helps keep UNIT_TEST()
declarations on a single line.

Give the enum a name and reference it from the UNIT_TEST() macros while
we are here.

bd9ff681bd serial: zynqmp: Fetch baudrate from dtb and update
The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.

To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f31 ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.

The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.

Also add test to cover this new function.

This patch adds UCLASS_SM with the generic API:

- sm_call_write()
- sm_call_read()

These functions operate with struct pt_regs, which describes

36e45f69c4 cmd: dm: allow for selecting uclass and device
The output from "dm tree" or "dm uclass" is a bit annoying
if the number of devices available on the system is huge.
(This is especially true on sandbox when I debug some DM code.)

With this patch, we can specify the uclass name or the device
name that we are interested in in order to limit the output.

For instance,

=> dm uclass usb
uclass 121: usb
0     usb@1 @ 0bcff8b0, seq 1

uclass 124: usb

=> dm tree usb:usb@1
 Class     Index  Probed  Driver                Name

 usb_emul      0  [   ]   usb_sandbox_hub           `-- hub-emul
 usb_emul      1  [   ]   usb_sandbox_flash             |-- flash-stick@0
 usb_emul      2  [   ]   usb_sandbox_flash             |-- flash-stick@1

 usb_emul      4  [   ]   usb_sandbox_keyb              `-- keyb@3

If you want forward-matching against a uclass or udevice name,
you can specify "-e" option.

=> dm uclass -e usb
uclass 15: usb_emul
0     hub-emul @ 0bcffb00, seq 0
1     flash-stick@0 @ 0bcffc30, seq 1

9e644284ab dm: core: Report bootph-pre-ram/sram node as pre-reloc after relocation
Nodes with bootph-pre-sram/ram props are bound in multiple phases:
1. At TPL (bootph-pre-sram) or SPL (bootph-pre-ram) phase
2. At U-Boot proper pre-relocation phase
3. At U-Boot proper normal phase

However the binding and U-Boot Driver Model documentation indicate that
only nodes marked with bootph-all or bootph-some-ram should be bound in
the U-Boot proper pre-relocation phase.

Change ofnode_pre_reloc to report a node with bootph-pre-ram/sram prop
with a pre-reloc status only after U-Boot proper pre-relocation phase.
Also update the ofnode_pre_reloc documentation to closer reflect the
binding and driver model documentation.

This changes behavior of what nodes are bound in the U-Boot proper
pre-relocation phase. Change to bootph-all or add bootph-some-ram prop
to restore prior behavior.

39d383bdac arm_ffa: introduce Arm FF-A support
Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0

The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.

This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.

The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.

All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.

Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.

FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.

The driver exports its operations to be used by upper layers.

Exported operations:

- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap

32dd07ff46 arm_ffa: introduce sandbox FF-A support
Emulate Secure World's FF-A ABIs and allow testing U-Boot FF-A support

Features of the sandbox FF-A support:

- Introduce an FF-A emulator
- Introduce an FF-A device driver for FF-A comms with emulated Secure World
- Provides test methods allowing to read the status of the inspected ABIs

The sandbox FF-A emulator supports only 64-bit direct messaging.

c09bfc666c arm_ffa: introduce Arm FF-A support
Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0

The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.

This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.

The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.

All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.

Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.

FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.

Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).

The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.

The driver exports its operations to be used by upper layers.

Exported operations:

- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap

Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c).
Arm specific methods are implemented in the Arm driver (arm-ffa.c).

For more details please refer to the driver documentation [2].

77224320f0 core: read: fix dev_read_addr_size()
The behaviour of dev_read_addr_size() is surprising as it does not
handle #address-cells and #size-cells but instead hardcodes the values
based on sizeof(fdt_addr_t).

This is different from dev_read_addr_size_index() and
dev_read_addr_size_name() both of which do read the cell sizes from the
device tree.

Since dev_read_addr_size() is only used by a single driver and this
driver is broken when CONFIG_FDT_64BIT does not match the address size
in the device tree, fix the function to behave like all of the other
similarly named functions.  Drop the property name argument as the only
caller passes "reg" and this is the expected property name matching the
other similarly named functions.

a8f2ac2ae6 fdt: Allow more general use of livetree
At present livetree can only be used for the control FDT. It is useful
to be able to use the ofnode API for other FDTs, e.g. those used by
the upcoming configuration editor.

We already have most of the support present, and tests can be marked with
the UT_TESTF_OTHER_FDT flag to use another FDT as a special case. But
with this change, the functionality becomes more generally available.

Plumb in the require support.

9cf39bbe96 fdt: Align the start of the livetree
Ensure that the block of memory used by live tree is aligned according to
the default for structures. This ensures that the root node appears at
the start of the block, so it can be used with free(), rather than being
4 bytes later in some cases.

This corrects a rather obscure bug in unflatten_device_tree().
