serial-uclass: reset gd->cur_serial_dev to NULL if serial not found
Reset gd->cur_serial_dev pointer to avoid calling non-relocated code
from relocated code if a serial driver is not found and
CONFIG_REQUIRE_SERIAL_CONSOLE is disabled.
Here is detailed explanation of what this patch is trying to fix.
U-boot calls the serial_find_console_or_panic() function twice.
The first console setup occurs before U-boot relocation in
the serial_init(). This stage uses simple FDT parsing and
assigns gd->cur_serial_dev to a "serial" device that lives in
non-relocated code too.
The second console setup after U-boot relocation(from serial_initialize())
may use full live DT (if OF_LIVE enabled) probe sequence with buses,
clocks, resets, etc... And if the console setup fails at this step,
than we should be caught by panic_str("No serial driver found").
But... If we disable CONFIG_REQUIRE_SERIAL_CONSOLE, than we
return from serial_init() with gd->cur_serial_dev pointing
to the "old"(non-relocated) serial device.
And if this area, where "old" serial device is placed, is changed
(e.g. Linux kernel may be relocated at this address), than we will get
an unexpected crash on the next call of printf().

pci: pcie-brcmstb: do not rely on CLKREQ# signal
When the Broadcom STB PCIe controller is initialized, it must be set
into one of three CLKREQ# modes: "none"/"aspm"/"l1ss". The Linux driver,
through today, hard-codes "aspm" since the vast majority of boards using
this driver have a fixed PCIe bus with the CLKREQ# signal wired up.
The Raspberry Pi CM4, however, can be connected to a plethora of PCIe
devices, some of which do not connect the CLKREQ# line (they just leave
it floating). So "aspm" mode is no longer appropriate in all cases. In
Linux, there is a proposed patchset [1] to determine the proper mode.
This doesn't really make sense in U-Boot's case, so we just change the
assumption from "aspm" to "none" (which is always safe).
This patch DOES resolve a real-world crash that occurs when U-Boot is
running on a Raspberry Pi CM4 installed in slot 3 of a Turing Pi 2
cluster board.

- Do not attempt to access the configuration space of a PCIe device if

- Wait for the recommended 100ms after PERST# is deasserted.

This patchset aims to bring two capsule related tasks under the U-Boot
build flow.
The first task is related to generation of capsules. The capsules can be
generated as part of U-Boot build, and this is being achieved through
binman, by adding a capsule entry type. The capsules can be generated by
specifying the capsule parameters as properties under the capsule entry
node.
The other task is the embedding of the public key into the platform's
DTB. The public key is in the form of an EFI Signature List(ESL) file
and is used for capsule authentication. This is being achieved by adding
the signature node containing the capsule public key in the platform's
DTB.
Corresponding changes have also been made to the test setup of the EFI
capsule update feature. The ESL public key file was embedded into the
sandbox platform's test.dtb as part of the test setup, post U-Boot
build. This is now no longer needed as the embedding of the ESL happens
as part of the build.
Secondly, the capsules needed for testing the EFI capsule update feature
were being generated through the invocation of the mkeficapsule tool.

capsules through binman.

blk: Add bounce buffer support to read/write operations
Some devices have limited DMA capabilities and require that the
buffers passed to them fit specific properties. Add new optional
callback which can be used at driver level to indicate whether a
buffer alignment is suitable for the device DMA or not, and
trigger use of generic bounce buffer implementation to help use
of unsuitable buffers at the expense of performance degradation.

Block devices with 4k sectors imply the MBR sectors are also 4k instead
of regular 512B. Avoid hard-coding the 512B sector size and isntead read
the current block device sector size from it, and if the sector size is
larger than 512B, use the block device sector size.

common: bouncebuf: Add missing cast to dma_addr_t
Fix the following warning produced on qemu-x86_64_defconfig:
"
common/bouncebuf.c: In function ‘bounce_buffer_stop’:
common/bouncebuf.c:82:34: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
82 | dma_unmap_single((dma_addr_t)state->bounce_buffer,
| ^
"
The warning is valid, the pointer has to be up-cast first.
