mmc: sdhci-cadence: trigger tuning for SD HS mode on SD6HC (v6) PHY
The Cadence SD6HC (SDHCI spec v4.20+) controller uses a soft PHY whose
DLL delay characteristics vary with PVT (Process, Voltage, Temperature)
and board-level trace routing.
A static delay value programmed via device tree for SD High Speed mode is
insufficient because the optimal sampling point varies per board, SD card,
and operating conditions. Runtime calibration is required.
While the SD Physical Layer Specification does not mandate tuning for
SD HS mode (only for UHS-I SDR50/SDR104), the Cadence SD6HC PHY
requires runtime calibration of its receive data delay line to find a
valid sampling window under constrained clock conditions.
The tuning is triggered from the set_ios_post callback because at that
moment hardware has committed the new bus width, clock frequency, and speed
mode to the controller registers. This ensuring the tuning sequence runs
at the correct SD HS operating conditions.
The tuning is gated by a device tree property "cdns,sd-hs-tuning" so
that only boards requiring runtime calibration opt in. When enabled,
the driver performs a 40-tap DLL sweep using CMD19 to find the largest
consecutive passing window, then programs the midpoint into
PHY_DLL_SLAVE_CTRL_REG.
To enable on a board, add to the MMC node in device tree:

In parse_config(), devname is dynamically allocated by sscanf().
When sscanf() fails to fill enough fields (rc < 3), devname is freed and
the loop continues to the next line. However, if the next call to sscanf()
fails to match (rc == 0), devname is not written and still holds the stale
freed pointer. The subsequent free(devname) then operates on
already-freed memory.
Fix this by resetting devname to NULL before each sscanf() call, so
that a non-matching call leaves a NULL pointer and the subsequent
free() becomes a harmless no-op.

usb: Correct dependencies around USB_EMUL
The symbol USB_EMUL is how sandbox has access to USB. It's
implementation however enforces a few other requirements. It must have
SCSI enabled, and in turn that means it must have BLK enabled. Finally,
we should not be using SANDBOX itself as a symbol to decide what to
build or not build here, as SANDBOX is selected for COMPILE_TEST builds
as well and so may not have enabled the sandbox specific USB support.

boot: image-fit.c: check target, not source, for 8-byte alignment when loading FDT
A number of our boards no longer boot with v2026.04, ironically as a
result of the effort to ensure 8-byte alignment of the dtb passed to
the kernel and getting rid of the fdt_high=0xffffffff.
The problem exists when the FIT image does specify a (properly
aligned) load address to use for the fdt. For example, we have
fdt-am335x-boneblack.dtb {
description = "Flattened Device Tree blob";
data = /incbin/(...);
...
load = <0x88000000>;
}
Now, with v2026.04 and depending on just exactly where that data ends
up, in a good case we see
Loading fdt from 0x8a8c6e10 to 0x88000000
Booting using the fdt blob at 0x88000000

Notice how the "Loading fdt from" line still claims to load the fdt to
that 0x88000000 address, but since this "else if" clause looks at the
source address (buf) and comes before the "else if (load != data)"
clause, we end up doing the "allocate another buffer to use as target"
instead of actually copying to 0x88000000, but then the "fdt_high=~0"
logic in boot_relocate_fdt() obviously fails to do an lmb-reservation
of that area, and the boot fails.
When there's no load= property in the fdt node, this should not change
anything. But when there is, it is the alignment of that target which
is relevant, not the alignment of the fdt blob within the FIT
image. With this patch applied, we instead get the expected

Coverity Scan defects are observed in fdtdec_apply_bloblist_dtos(),

Validate the bloblist FDT with fdt_check_full() before calling

blob while keeping the existing flow unchanged.
Also normalize libfdt return codes from this path to errno values,
including the overlay callback path through bloblist_apply_blobs().

Makefile: remove block from conv=block, sync in SPL alignment dd
The line that produces $(SPL_BIN)-align.bin invokes dd with
conv=block,sync but no cbs= operand. The result of dd conv=block
without cbs= is unspecified. GNU coreutils outputs anyway, but
uutils (default in Ubuntu 26.04 LTS) errors out for files with
newlines, including SPL binaries, producing:
dd: conv=block or conv=ubnblock specified without cbs=N
Either the block operand must be removed, or cbs=N must be added.
conv=block is for converting newline-terminated variable-length
records to fixed-length space-padded ones, which is meaningless
for a binary SPL image. The intent of the rule is 4-byte
alignment, which conv=sync alone provides by padding the final
block to bs= bytes with NULs.
During build, u-boot-spl-align.bin errors silently due to '@'.

Backward compatibility is maintained by reading the legacy boolean

legacy values are used transparently, so existing device trees remain
functional without modification.
