The following command triggers a segfault in search_dir:
./sandbox/u-boot -c 'host bind 0 ./sandbox/test/fs/3GB.ext4.img ;

The following command triggers a segfault in check_filename:

ext4write host 0 0 /. 0x10'
"." is the first entry in the directory, thus previous_dir is NULL. The
whole previous_dir block in search_dir seems to be a bad copy from
check_filename(...). As the changed data is not written to disk, the
statement is mostly harmless, save the possible NULL-ptr reference.
Typically a file is unlinked by extending the direntlen of the previous
entry. If the entry is the first entry in the directory block, it is
invalidated by setting inode=0.
The inode==0 case is hard to trigger without crafted filesystems. It only
hits if the first entry in a directory block is deleted and later a lookup
for the entry (by name) is done.

Makefile: rm u-boot.cfg dependencies are missing
Prior to the previous patch, a freshly created .u-boot.cfg.cmd may not
correctly represent all dependencies for u-boot.cfg. The previous change
only solved this issue for fresh builds; when performing an incremental
build, the deficient .u-boot.cfg.cmd is already present, so u-boot.cfg
is not rebuilt, and hence .u-boot.cfg.cmd is not rebuilt with the correct
content.
Solve this by explicitly detecting when the dependency file .u-boot.cfg.d
has not been integrated into .u-boot.cfg.cmd, and force u-boot.cfg to be
rebuilt in this case by deleting it first. This is possible since
if_changed_dep will always delete .u-boot.cfg.d when it executes
successfully, so its presence means either that the previous build was
made by a source tree that contained a Makefile that didn't include the
previous patch, or that the build failed part way through executing
if_changed_dep for u-boot.cfg. Forcing a rebuild of u-boot.cfg is required
in the former case, and will cause no additional work in the latter case,
since the file would be rebuilt anyway for the same reason it was being
rebuilt by the previous build.

Makefile: use if_change_dep for u-boot.cfg
cmd_cpp_cfg generates a dependency output, but because it's invoked using
if_changed rather than if_changed_dep, that dependency file is ignored.
This results in Kbuild not knowing about which files u-boot.cfg depends
on, so it may not be rebuilt when required.
A practical result of this is that u-boot.cfg may continue to reference
CONFIG_ options that no longer exist in the source tree, and this can
cause the adhoc config options check to fail.
This change modifies Makefile to use if_changed_dep, which in turn causes
all dependencies to be known to the next make invocation.

image-fit: Fix fit_get_node_from_config semantics
Commit
bac17b78dace ("image-fit: switch ENOLINK to ENOENT") changed
fit_get_node_from_config to return -ENOENT when a property doesn't
exist, but didn't change any of its callers which check return values.
Notably it didn't change boot_get_ramdisk, which leads to U-Boot failing
to boot FIT images which don't include ramdisks with the following
message:
Ramdisk image is corrupt or invalid
It also didn't take into account that by returning -ENOENT to denote the
lack of a property we lost the ability to determine from the return
value of fit_get_node_from_config whether it was the property or the
configuration node that was missing, which may potentially lead callers
to accept invalid FIT images.
Fix this by having fit_get_node_from_config return -EINVAL when the
configuration node isn't found and -ENOENT when the property isn't
found, which seems to make semantic sense. Callers that previously
checked for -ENOLINK are adjusted to check for -ENOENT, which fixes the
breakage introduced by commit
bac17b78dace ("image-fit: switch ENOLINK
to ENOENT").
The only other user of the return fit_get_node_from_config return value,
indirectly, is bootm_find_os which already checked for -ENOENT. From a
read-through of the code I suspect it ought to have been checking for
-ENOLINK prior to
bac17b78dace ("image-fit: switch ENOLINK to ENOENT")
anyway, which would make it right after this patch, but this would be
good to get verified by someone who knows this x86 code or is able to
test it.

bytes of data at once. The register group QSPI_SPI_DATA_REG_3,
QSPI_SPI_DATA_REG_2, QSPI_SPI_DATA_REG_1 and QSPI_SPI_DATA_REG is
treated as a single 128-bit word for shifting data in and out. The bit
at QSPI_SPI_DATA_REG_3[31] position is the first bit to be shifted out
in case of 128 bit transfer mode. Therefore the first byte to be written
to flash should be at QSPI_SPI_DATA_REG_3[31-25] position.
Instead of writing 1 byte at a time when interacting with SPI NOR flash,

MIPS: Fix cache maintenance in relocate_code & simplify
The relocate_code function was handling cache maintenance incorrectly.
It copied U-Boot to its new location, flushed the caches & then
proceeded to apply relocations & jump to the new code without flushing
the caches again. This is problematic as the instruction cache could
potentially have already fetched instructions that hadn't had relocs
applied.
Rework this to perform the flush_cache call using the code in the
original copy of U-Boot, after having applied relocations to the new
copy of U-Boot. The new U-Boot can then be jumped to safely once that
cache flush has been performed.
As part of this, since the old U-Boot is used up until after that cache
flush, complexity around loading values from the GOT using a jump & link
instruction & loads from a table is removed. Instead we can simply load
the needed values with PTR_LA fromt the original GOT.

pci: Flip condition for detecting non-PCI parent devices
In pci_uclass_pre_probe an attempt is made to detect whether the parent
of a device is a PCI device and that the device is thus a bridge. This
was being done by checking whether the parent of the device is of the
UCLASS_ROOT class. This causes problems if the PCI controller is a child
of some other non-PCI node, for example a simple-bus node.
For example, if the device tree contains something like the following
then pci_uclass_pre_probe would incorrectly believe that the PCI
controller is a bridge, with a PCI parent:
/ {
some_child {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <>;

the parent devices class is UCLASS_PCI and treating a device as a bridge
when this is true, making use of device_is_on_pci_bus to perform this
test.
