Raymond MaoandTom Rini 0708d54a56 mbedtls: remove incorrect attribute type checker
S/MIME Capabilities (OID: 1.2.840.113549.1.9.15) attributes are
expected to be algorithms but neither data nor MS Inderect Data,
thus the checker for data type is incorrect.

This patch fixes a capsule authentication failure with PKCS#7
message that contains S/MIME capabilities, which formed by the EDK2
GenerateCapsule tool.

S/MIME Capabilities are not common attributes in an EFI capsule,
thus this failure cannot be reproduced with the capsules generated
via mkeficapsule.

Tom Rini cf6d4535cc x86: emulation: Disable bloblist for now
As reported by Niklas Sombert, enabling bloblist on these platforms
means that we currently don't pass SMBIOS tables on to later stages. For
the v2025.04 release, disable bloblists as that is sufficient to restore
functionality and we will address the underlying problem for the next
release.

Since commit 61040097a9 ("reset: at91: Add reset driver for basic

the sama5d2 reset controller in sama5d2.dtsi is not handled by

Paul BarkerandJerome Forissier 64b973fc78 cmd: Kconfig: Fix submenu for network commands
The Kconfig parser seems to get confused by the current if conditions
following CMD_NET and displays all network command options directly in
the "Command line interface" menu instead of in a "Network commands"
submenu.

To help out Kconfig we can simplify the if conditions, so that the
definition of CMD_NET is followed immediately by an if/endif block that
contains all network command options. We can also remove nested checks
for CMD_NET or (NET || NET_LWIP).

Ilias ApalodimasandJerome Forissier f93b15e706 net: lwip: Remove error print on failed tx
When an ethernet driver fails to send a frame we print an error in lwIP.
But depending on how often that error is it might significantly delay
transmissions.

For example downloading a big file with the rpi4 spams the console with
'send error: -101', but removing the print makes the file download with
an average speed of ~8.5MiB/s since the packets are retransmitted.

So let's move it to a 'debug' in lwIP and expect ethernet drivers to handle
the failure if it's severe.

Stefan EichenbergerandTom Rini 7ad5436194 board: verdin-am62: remove spl_perform_fixups
spl_perform_fixups is redundant in the current implementation. SPLs call
dram_init during spl_enable_cache in arch/arm/mach-k3/common.c. In
U-Boot, dram_init and dram_init_banksize are automatically called in
init_sequence_f. Therefore, SPLs and U-Boot always determine the correct
RAM size. During Linux boot, fdt_fixup_memory_banks adjusts the RAM size
in the Linux device tree, ensuring correct RAM usage.

dram_init() calls get_ram_size() for the Verdin AM62, which determines
the correct RAM size through read/write operations. However, due to the
K3 bootflow placing ATF in RAM and requiring cache coherence, calling
get_ram_size() with caches enabled prevents ATF boot. Removing this call
restores ATF boot functionality.

This fixes a regression introduced in commit 4164289db8 ("board:
verdin-am62: fix missing memory fixup call") which prevents some of our
Verdin AM62 modules from booting.

Sam EdwardsandHeinrich Schuchardt 408a20e099 efi_loader: Move .dynamic out of .text in EFI
EFI applications need to be relocatable. Ordinarily, this is achieved
through a PE-format .reloc section, but since that requires toolchain
tricks to achieve, U-Boot's EFI applications instead embed ELF-flavored
relocation information and use it for self-relocation; thus, the
.dynamic section needs to be preserved.

Before this patch, it was tacked on to the end of .text, but this was
not proper: A .text section is SHT_PROGBITS, while the .dynamic section
is SHT_DYNAMIC. Attempting to combine them like this creates a section
type mismatch. While GNU ld doesn't seem to complain, LLVM's lld
considers this a fatal linking error.

This patch moves .dynamic out to its own section, so that the output ELF
has the correct types. (They're all mashed together when converting to
binary anyway, so this patch causes no change in the final .efi output.)

Sam EdwardsandHeinrich Schuchardt 214a87757a arm: riscv: efi: Export _start symbol from crt0_*_efi stubs
While the _start label is only intended for use locally to populate the
(hand-written) PE header, the linker script includes ENTRY(_start) which
designates it as the entry point in the output ELF, resulting in linker
warnings under some linkers (e.g. LLVM's lld) due to _start not being a
globally-visible symbol. Since  ELF is only an intermediary build
format, and the aforementioned PE header correctly points to _start, the
ENTRY(_start) directive could easily be removed to silence this warning.

However, since some developers who are debugging EFI by analyzing the
intermediary ELF may appreciate having correct entry-point information,
this patch instead promotes the _start labels to global symbols,
silencing the linker warning and making the intermediary ELF reflect the
true entry point.

This patch doesn't affect the final output binaries in any way.

Marek Vasut 885fd621a3 ram: renesas: dbsc5: Make struct renesas_dbsc5_board_config public
Make struct renesas_dbsc5_board_config {} definition public via
include/dbsc5.h, so this structure can be defined in board files
and passed into the DBSC5 DRAM driver by overriding weak function
dbsc5_get_board_data() on board level.

Marek Vasut 74e2811361 ram: renesas: dbsc5: Add V4H-3/V4H-5/V4H-7 OTP based detection
Add auto-detection and handling of Renesas R-Car V4H-3 and V4H-5
in addition to V4H-7 SoC variants based on OTP fuse programming.
The V4H-3 and V4H-5 variants have reduced DRAM frequency options.

Marek Vasut 9ae94d2aed ram: renesas: dbsc5: Synchronize initialization code to rev.1.10
Update the DRAM initialization code to match DBSC5 initialization code
rev.1.10 , which is currently the latest version available. This makes
DRAM initialization operational on Renesas R-Car V4H R8A779G0 rev.3.0.

Marek Vasut da7662f6bb ram: renesas: dbsc5: Fix DBTR11 calculation
Reinstate missing increment by two in DBTR11 calculation based
on the original DBSC5 initialization code rev.0.80. The original
code did ... ODTLon - (js2[JS2_tODTon_min] - 1) + 1 , which was
incorrectly converted into ODTLon - js2[JS2_tODTon_min], but
should have been converted to ODTLon - js2[JS2_tODTon_min] + 2.
Add the missing +2 .

Marek Vasut 9a106f15fa ram: renesas: dbsc5: Fix JS1 index calculation
The JS1 index is calculated correctly, but the limiter cannot
be the max() function because the index should be lower than
JS1_USABLEC_SPEC_HI and the max() function would unconditionally
override the JS1 index to JS1_USABLEC_SPEC_HI. Use clamp() to
limit the JS1 index instead.

Marek Vasut 15111aeb9c arm64: dts: renesas: Make OTP available in SPL on R8A779G0 V4H
The DBSC5 DRAM controller driver needs access to OTP fuses to discern
Renesas R-Car V4H-3, V4H-5 and V4H-7 SoC variants based on OTP fuse
programming. Make OTP block DT node available in U-Boot SPL DT so the
DBSC5 driver can determine its base address and read out the OTP fuses.

Marek Vasut 92659829aa arm64: renesas: Drop stale R-Car V4H SPL implementation description
The R-Car V4H SPL implementation was originally running on the Cortex-R52
core, but this is no longer the case. Majority of the SPL now runs on the
Cortex-A76 core. Drop the stale description.
