Merge patch series "boot: Support priority for global bootmeths"
Simon Glass <sjg@chromium.org> says:
At present global bootmeths always run first, before all other
bootmeths. Optimisations in the code take advantage of this, putting
them at the end, so they can be used once and then forgotten.
In some cases it is useful to run global bootmeths later in the boot.
For example, the EFI-bootmgr bootmeth may itself scan devices and the
network, so running it first can hold up the boot significantly for
boards not actually relying on EFI-bootmgr to boot.
This series introduces a new field in global bootmeths which indicates
the priority, using the same scheme as is used with bootdev hunters.
Thus it is possible to insert the EFI-bootmgr bootmeth just before the
hunter for network bootdevs is invoked.
Despite the simplicity of the concept and the relatively small series,
this is a fairly significant enhancement. It is also quite tricky to
implement, largely due to the way the original code was written, with
global bootmeths being a small, size-optimised add-on to the original
bootstd implementation.
For now we only allow each global bootmeth to run at most once, but this
implementation is written in a way that we could relax that if needed.
Then the bootmeth itself could decide whether to run at any particular
point in the bootflow iteration.

- phy_select_page(): Switch to a specific page and return previous page

These helpers allow safe access to paged PHY registers by ensuring
proper page selection and restoration,

Continuing from the last series[1], this patch series addresses the requirement
to disable the args file in falcon mode.
The args file is used in falcon mode for loading the device-tree for the kernel.
However in secure falcon mode, the expected payload is a FIT containing a signed
device-tree and kernel image. Thus removing the need to load the extra args
file in the first place. Also, loading the extra file without any authentication
mechanism exposes an attack vector and should therefore be disabled to keep the
boot secure.
This patch set builds on the last few to first optionally allow for loading the

The series also introduces the new SPL_OS_BOOT_SECURE config symbol which

static int spl_<bootmedia>_load_image(...) {

serial: sh: Handle HSCIF RX FIFO overflow
The HSCIF RX FIFO may overflow when data are streaming from remote end
into the HSCIF while U-Boot is still starting up. In that case, HSFSR
bit RDF is set, but HSFDR field R is zero. This confuses .tstc callback
into considering RX FIFO to be empty, which leads to .getc to be never
invoked, even when user attempts to pass more input onto the command
line.
Fix this by considering the RDF flag in serial_rx_fifo_level(), which
is called from .tstc in case of no errors. If RDF flag is set, trigger
the .getc callback and let it clear the RX FIFO.

virito: blk: fix logic to determine block sizes
With commit
c85b8071e7d3 ("virtio: blk: support block sizes exceeding 512
bytes") logic was added to detect the VIRTIO_BLK_F_BLK_SIZE capability and
to copy the block size reported by QEMU to the block device descriptor.
The logical block size can be set when invoking QEMU:
-drive if=none,file=4096.img,format=raw,id=vda \
-device virtio-blk-device,drive=vda,physical_block_size=4096,logical_block_size=4096
In U-Boot the logical block size is shown by command `virtio info`:
=> virtio info
Device 0: QEMU VirtIO Block Device
Type: Hard Disk
Capacity: 1024.0 MB = 1.0 GB (262144 x 4096)
There where two flaws which together hid that the logic was incorrect:
* VIRTIO_BLK_F_BLK_SIZE was missing in the driver capabilities and the bit
was filtered out.
* The result of the call to virtio_has_feature() was negated.
The problem became apparent when using ARM FVP as emulator which does not set
VIRTIO_BLK_F_BLK_SIZE.
