98ef128b56 include/configs: aspeed: Remove hardcoded variables
The hardcoded platform variables such as DRAM base address are not
common to Aspeed SoCs AST24xx/AST25xx/AST26xx. This patch replaces
those hardcoded with macros defined in a newly added header, where
the basic SoC HW information are assigned accordingly.

52956e535e efi_loader: signature: correct a behavior against multiple signatures
Under the current implementation, all the signatures, if any, in
a signed image must be verified before loading it.

Meanwhile, UEFI specification v2.8b section 32.5.3.3 says,
    Multiple signatures are allowed to exist in the binary’s certificate
    table (as per PE/COFF Section “Attribute Certificate Table”). Only
    one hash or signature is required to be present in db in order to pass
    validation, so long as neither the SHA-256 hash of the binary nor any
    present signature is reflected in dbx.

This patch makes the semantics of signature verification compliant with
the specification mentioned above.

313981c2d9 common/board_f: make sure to call fix_fdt() before reserve_fdt()
There may be a chance that board specific fix_fdt() will change the

otherwise global data (gd) will overwrite with FDT blob values.

7c6ca03eae riscv: additional crash information
If an exception occurs, the relocated program counter and return address
are required for an analysis.

With this patch you get:

    => exception undefined

    Unhandled exception: Illegal instruction
    EPC: 0000000080595908 RA: 000000008059c0c6 TVAL: 000000008030c01e
    EPC: 0000000080007908 RA: 000000008000e0c6 reloc adjusted

We can use the relocated addresses to find the involved functions in
u.boot.map:

    .text.do_undefined
                0x0000000080007908        0x8 cmd/built-in.o
    .text.cmd_process

                0x000000008000dfcc                cmd_process

If an exception occurs in an UEFI binary additionally the load addresses of
the UEFI binaries are needed. With this patch:

    => setenv efi_selftest exception
    => bootefi selftest

    Unhandled exception: Illegal instruction
    EPC: 000000008042e18a RA: 000000008042e18a TVAL: 000000008030c01e

f68a6d5835 efi_loader: variable: fix secure state initialization
Under the new file-based variable implementation, the secure state
is always and falsely set to 0 (hence, the secure boot gets disabled)
after the reboot even if PK (and other signature database) has already
been enrolled in the previous boot.

This is because the secure state is set up *before* loading non-volatile
variables' values from saved data.

This patch fixes the order of variable initialization and secure state
initialization.

1115edd846 efi_loader: signature: rework for intermediate certificates support
In this commit, efi_signature_verify(with_sigdb) will be re-implemented
using pcks7_verify_one() in order to support certificates chain, where
the signer's certificate will be signed by an intermediate CA (certificate
authority) and the latter's certificate will also be signed by another CA
and so on.

What we need to do here is to search for certificates in a signature,
build up a chain of certificates and verify one by one. pkcs7_verify_one()
handles most of these steps except the last one.

pkcs7_verify_one() returns, if succeeded, the last certificate to verify,
which can be either a self-signed one or one that should be signed by one
of certificates in "db". Re-worked efi_signature_verify() will take care
of this step.

0658bb29b0 efi_loader: variable: keep temporary buffer during the authentication
This is a bug fix; Setting an authenticated variable may fail due to
a memory corruption in the authentication.

A temporary buffer will, if needed, be allocated to parse a variable's
authentication data, and some portion of buffer, specifically signer's
certificates, will be referenced by efi_signature_verify().

So the buffer should be kept valid until the authentication process
is finished.

82bf7729a2 mtd: rawnand: stm32_fmc2: get resources from parent node
FMC2 EBI support has been added. Common resources (registers base
address and clock) can now be shared between the 2 drivers using
"st,stm32mp1-fmc2-nfc" compatible string. It means that the
common resources should now be found in the parent device when EBI
node is available.

7a6b328841 mtd: rawnand: stm32_fmc2: cosmetic change to use nfc instead of fmc2 where relevant
This patch renames functions and local variables.
This cleanup is done to get all functions starting by stm32_fmc2_nfc
in the FMC2 raw NAND driver when all functions will start by
stm32_fmc2_ebi in the FMC2 EBI driver.

4a470044e1 mtd: rawnand: stm32_fmc2: use FMC2_TIMEOUT_5S for timeouts
FMC2_TIMEOUT_5S will be used each time that we need to wait.
It was seen, during stress tests in an overloaded system,
that we could be close to 1 second, even if we never met this
value. To be safe, FMC2_TIMEOUT_MS is set to 5 seconds.
