de58ac49a5 armv8: psci: skip setup code if we are not EL3
If we are running in EL2 skip PSCI implementation setup. This avoids an
exception if CONFIG_ARMV8_PSCI is set, but u-boot is started by TF-A.

cb14cc8867 armv8: layerscape: get rid of smc_call()
There are two different implementations to do a secure monitor call:
smc_call() and arm_smccc_smc(). The former is defined in fwcall.c and
seems to be an ad-hoc implementation. The latter is imported from linux.

smc_call() is also only available if CONFIG_ARMV8_PSCI is not defined.
This makes it impossible to have both PSCI calls and PSCI implementation
in one u-boot build. The layerscape SoC code decide at runtime via
check_psci() if there is a PSCI support. Therefore, this is a
prerequisite patch to add PSCI implementation support for the layerscape
SoCs.

Note, for the TFA part, this is only compile time tested with
(ls1028ardb_tfa_defconfig).

eb217200ef armv8: include psci_update_dt() unconditionally
psci_update_dt() is also required if CONFIG_ARMV8_PSCI is set, that is,
if u-boot is the PSCI provider.
Guard the check which is intended to call into the PSCI implementation
in the secure firmware, by the proper macro SEC_FIRMWARE_ARMV8_PSCI.

Mark the function as weak because - unfortunately - there is already
a stub of the same function in arch/arm/mach-rmobile/psci-r8a779a0.c
which does not the same as the common one.

881284b36a arm: layerscape: Disable erratum A009007 on LS1021A, LS1043A, and LS1046A
This erratum is reported to cause problems on these processors [1-3].
The problem is usually with the clocking, which is supposed to be
configured by the RCW [4]. However, if it is not set, or if the default
clocking is not correct, then this erratum will cause an SError.
However, according to Ran Wang in [1]:
" ... this erratum is used to pass USB compliance test only, you could
 disable this workaround on your board if you don't any USB issue on
 normal use case, I think it's fine."

So just disable this erratum by default for these processors.

1b0eec3c9f ARM: dts: at91: sama7g5ek: Align the impedance of the QSPI0's HSIO and PCB lines
The impedance of the QSPI PCB lines on the sama7g5ek is 50 Ohms.
Align the output impedance of the QSPI0 HSIOs by setting a medium drive
strength which corresponds to an impedance of 56 Ohms when VDD is in the
3.0V - 3.6V range. The high drive strength setting corresponds to an
output impedance of 42 Ohms on the QSPI0 HSIOs.
This is just a fine tunning. The memory that we have populated on sama7g5ek
works fine even with high drive strength, but it's better to adjust it and
use medium instead, in case some other flashes with higher frequencies are
tested.

8cfac237b9 Merge branch '2022-04-25-initial-implementation-of-stdboot'
To quote the author:
The bootflow feature provide a built-in way for U-Boot to automatically
boot an Operating System without custom scripting and other customisation.
This is called 'standard boot' since it provides a standard way for
U-Boot to boot a distro, without scripting.

It introduces the following concepts:

   - bootdev - a device which can hold a distro
   - bootmeth - a method to scan a bootdev to find bootflows (owned by
                U-Boot)
   - bootflow - a description of how to boot (owned by the distro)

This series provides an implementation of these, enabled to scan for
bootflows from MMC, USB and Ethernet. It supports the existing distro
boot as well as the EFI loader flow (bootefi/bootmgr). It works
similiarly to the existing script-based approach, but is native to
U-Boot.

With this we can boot on a Raspberry Pi 3 with just one command:

   bootflow scan -lb

which means to scan, listing (-l) each bootflow and trying to boot each
one (-b). The final patch shows this.

With a standard way to identify boot devices, booting become easier. It
also should be possible to support U-Boot scripts, for backwards
compatibility only.

...

The design is described in these two documents:

82337bb6b6 binman: Refuse to replace sections for now
Binman interfaces allow attempts to replace any entry in the image with
arbitrary data. When trying to replace sections, the changes in the
section entry's data are not propagated to its child entries. This,
combined with how sections rebuild their contents from its children,
eventually causes the replaced contents to be silently overwritten by
rebuilt contents equivalent to the original data.

Add a simple test for replacing a section that is currently failing due
to this behaviour, and mark it as an expected failure. Also, raise an
error when replacing a section instead of silently pretending it was
replaced.

makes it easier to test replacing these entries as we can write tests
using an existing helper function that relies on extracting the replaced

Add tests that replace leaf entries in FIT subsections with data of
various sizes. Replacing the subsections or the whole FIT section does
not work yet due to the section contents being re-built from unreplaced
subentries' data.

74d3b2311d binman: Create FIT subentries in the FIT section, not its parent
When reading images from a file, each entry's data is read from its
parent section as specified in the Entry.Create() call that created it.
The FIT entry type has been creating its subentries under its parent
(their grandparent), as creating them under the FIT entry resulted in an
error until FIT was converted into a proper section.

FIT subentries have their offsets relative to the FIT section, and
reading those offsets in the parent section results in wrong data. The
subentries rightfully belong under the FIT entries, so create them
there. Add tests checking that we can extract the correct data for a FIT
entry and its subentries.

e736878b08 binman: Remove '/images/' fragment from FIT subentry paths
Binman FIT entry nodes describe their subentries in an 'images' subnode,
same as how they would be written for the mkimage executable. The entry
type initially manually managed its subentries keyed by their node paths
relative to its base node. It was later converted to a proper section
while still keeping the same keys for subentries.

These subentry keys of sections are used as path fragments, so they must
not contain the path separator character '/'. Otherwise, they won't be
addressable by binman extract/replace commands. Change these keys from
the '/images/foo' forms to the subentry node names. Extend the simple
FIT tests to check for this.

e2ce4fb986 binman: Don't reset offset/size if image doesn't allow repacking
When an image has the 'allow-repack' property, binman includes the
original offset and size properties from the image description in the
fdtmap. These are later used as the packing constraints when replacing
entries in an image, so other unconstrained entries can be freely
positioned.

Replacing an entry in an image without 'allow-repack' (and therefore the
original offsets) follows the same logic and results in entries being
merely concatenated. Instead, skip resetting the calculated offsets and
sizes to the missing originals for these images so that every entry is
constrained to its existing offset/size.

Add tests that replace an entry with smaller or equal-sized data, in an
image that doesn't allow repacking. Attempting to do so with bigger-size
data is already an error that is already being tested.

8ee4ec9bf5 binman: Collect bintools for images when replacing entries
Binman entries can use other executables to compute their data, usually
in their ObtainContents() methods. Subclasses of Entry_section would use
bintools in their BuildSectionData() method instead, which is called
from several places including their Pack().

These binary tools are resolved correctly while building an image from a
device-tree description so that they can be used from these methods.
However, this is not being done when replacing entries in an image,
which can result in an error as the Pack() methods attempt to use them.

Collect and resolve entries' bintools also when replacing entries to fix
Pack() errors. Add a way to mock bintool usage in the testing entry type
and tests that check bintools are being resolved for such an entry.

67bf2c8ded binman: Fix unique names having '/.' for images read from files
Binman can embed a copy of the image description into the images it
builds as a fdtmap entry, but it omits the /binman/<image-name> prefix
from the node paths while doing so. When reading an already-built image
file, entries are reconstructed using this fdtmap and their associated
nodes still lack that prefix.

Some entries like fit and vblock create intermediate files whose names
are based on an entry unique name. This name is constructed from their
node's path by concatenating the parents with dots up to the binman
node, e.g. /binman/image/foo/bar becomes 'image.foo.bar'.

However, we don't have this /binman/image prefix when replacing entries
in such an image. The /foo/bar entry we read when doing so erroneously
has the unique name of '/.foo.bar', causing permission errors when the
entry attempts to create files based on that.

Fix the unique-name generation by stopping at the '/' node like how it
stops at the binman node. As the unique names are used as filenames, add
tests that check if they're safe to use as filenames.

For now this requires the 'pxe' command be enabled. Future work may tidy
this up so that it can be used without CONFIG_CMDLINE being enabled.

b8aa463e9b bootstd: mmc: Add a bootdev driver
Add a bootdev driver for MMC. It mostly just calls the bootdev helper
function.

Add a function to obtain the block device for an MMC controller.

Fix up the comment for mmc_get_blk_desc() while we are here.

31aefaf89a bootstd: Add an implementation of distro boot
Add a bootmeth driver which handles distro boot from a disk, so we can
boot a bootflow using this commonly used mechanism.

In effect, this provides the same functionality as the 'sysboot' command
and shares the same code. But the interface into it is via a bootmeth.

For now this requires the 'pxe' command be enabled. Future work may tidy
this up so that it can be used without CONFIG_CMDLINE being enabled.
