6032292534 rng: stm32: add error concealment sequence
Seed errors can occur when using the hardware RNG. Implement the
sequences to handle them. This avoids irrecoverable RNG state.

Try to conceal seed errors when possible. If, despite the error
concealing tries, a seed error is still present, then return an error.

A clock error does not compromise the hardware block and data can
still be read from RNG_DR. Just warn that the RNG clock is too slow
and clear RNG_SR.

commit 0920ccdf41e3078a4dd2567eb905ea154bc826e6 Linux upstream.

Add support for bxcan (Basic eXtended CAN controller) to STM32F746. The
chip contains three CAN peripherals, CAN1 and CAN2 in dual peripheral
configuration and CAN3 in single peripheral configuration:
- Dual CAN peripheral configuration:
  * CAN1: Primary bxCAN for managing the communication between a secondary
    bxCAN and the 512-byte SRAM memory.
  * CAN2: Secondary bxCAN with no direct access to the SRAM memory.
  This means that the two bxCAN cells share the 512-byte SRAM memory and
  CAN2 can't be used without enabling CAN1.
- Single CAN peripheral configuration:
  * CAN3: Primary bxCAN with dedicated Memory Access Controller unit and
    512-byte SRAM memory.

7cfdacbe80 configs: sifive: enable poweroff command on Unmatched
Powering off the SiFive HiFive Unmatched board is supported both via the
SBI and GPIO sysreset drivers. See device-tree entry

    compatible = "gpio-poweroff".

Enable the poweroff command.

8a0d5f2f51 riscv: andesv5: Prefer using the generic RISC-V timer driver in S-mode
The Andes PLMT driver directly accesses the mtime MMIO region,
indicating its intended use in the M-mode boot stage. However,
since U-Boot proper (S-mode) also uses the PLMT driver, we need
to specifically mark the region as readable through PMPCFGx (or
S/U-mode read-only shared data region for Smepmp) in OpenSBI.

Granting permission for this case doesn't make sense. Instead,
we should use the generic RISC-V timer driver to read the mtime
through the TIME CSR. Therefore, we add the SPL_ANDES_PLMT_TIMER
config, which ensures that the PLMT driver is linked exclusively
against M-mode U-Boot or U-Boot SPL binaries.

e637e455ca riscv: enable CONFIG_DEBUG_UART by default
Most boards don't enable the pre-console buffer. So we will not see any
early messages. OpenSBI 1.3 provides us with the debug console extension
that can fill this gap.

For S-Mode U-Boot enable CONFIG_DEBUG_UART by default.
