Currently CONFIG_SPL_TEXT_BASE and CONFIG_SYS_TEXT_BASE addresses are
manually increased by 0x1000 due to .bootpg section. This section has size
of 0x1000 bytes and is manually put by linker script before .text section
(and therefore before base address) when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Due to this fact lot of other config options are manually increased by
0x1000 value to make correct layout. Note that entry point is not on
CONFIG_SPL_TEXT_BASE (image+0x1000) but it is really on address
CONFIG_SPL_TEXT_BASE-0x1000 (means at the start of the image).

Cleanup handling of .bootpg section when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Put .bootpg code directly into .text section and move text base
address to the start of .bootpg code. And finally remove +0x1000 value from
lot of config options. With this removal custom PHDRS is not used anymore,
so remove it too.

After this change entry point would be at CONFIG_SPL_TEXT_BASE and not at

- REMAKE_ELF was already enabled but u-boot file can't be used because

  u-boot.elf which should be used.

- Add support for early relocation when u-boot.bin is loaded to different
  address then CONFIG_SYS_TEXT_BASE

This series introduces ASAN and a basic fuzzing infrastructure that
works with sandbox. The example fuzz test towards the end of the series

series "virtio: Harden and test vring" that needs to be applied for the
final patch in this series.

There is some refactoring to stop using '.' prefixed sections. ELF
defines sections with names that contain anything that isn't
alphanumeric or an underscore as being for system use which means
clang's ASAN instrumentation happily add redzones between the contained
objects. That's not what we want for things like linker lists where the
linker script has carefully placed the sections contiguously. By
renaming the sections, clang sees them as user sections and doesn't add
instrumentation.

ASAN is left disabled by default as there are still some tests that it
triggers on and will need some more investigation to fix. It can be
enabled with CONFIG_ASAN or passing `-a ASAN` to buildman.

Use PSCI device to query Arm SMCCC v1.1 support from secure monitor
and if so, bind drivers for the SMCCC features that monitor supports.

Drivers willing to be bound from Arm SMCCC features discovery can use
macro ARM_SMCCC_FEATURE_DRIVER() to register to smccc feature discovery,
providing target driver name and a callback function that returns
whether or not the SMCCC feature is supported by the system.

during initialization. As per DT binding documentation, some SCMI

given SCMI protocols. It allows SCMI protocols to pass messages
concurrently each other.

devm_scmi_of_get_channel() for SCMI drivers probe sequences to get
a reference to the SCMI channel assigned to its related SCMI protocol.
The function queries the channel reference to its SCMI transport driver
through new scmi agent uclass operator .of_get_channel that uses Device
Tree information from related SCMI agent node.

Operator .of_get_channel returns a reference to the SCMI channel
assigned to SCMI protocol used by the caller device. SCMI transport
drivers that do not support multi-channel are not mandated to register
this operator. When so, API function devm_scmi_of_get_channel() returns
NULL and SCMI transport driver are expected to retrieve by their own
means the reference to the unique SCMI channel, for example using
platform data as these drivers currently do in U-Boot source tree.
