ARM: stm32: Add IWDG handling into PSCI suspend code
In case the IWDG is enabled by either U-Boot or Linux, the IWDG can never
be disabled again. That includes low power states, which means that if the
IWDG is enabled, the SoC would reset itself after a while in suspend via
the IWDG. This is not desired behavior.
It is possible to enable IWDG pre-timeout IRQ which is routed into the EXTI,
and use that IRQ to wake the CPU up before the IWDG timeout is reached and
reset is triggered. This pre-timeout IRQ can be used to reload the WDT and
then suspend the CPU again every once in a while.
Implement this functionality for both IWDG1 and IWDG2 by reading out all
the unmasked IRQs, comparing the list with currently pending IRQs in GICv3:
- If any IRQ is pending and it is NOT IWDG1 or IWDG2 pre-timeout IRQ,
wake up and let OS handle the IRQs
- If IWDG1 or IWDG2 IRQ is pending and no other IRQ is pending,
ping the respective IWDG and suspend again
This does not seem to have any adverse impact on power consumption in suspend.

we end up always running the full init. The reason is 'tpm init'
returns -EBUSY if the tpm is already open, while 'tpm autostart' handles
ths gracefully and continues with the initialization. It's worth noting
that this won't affect the device functionality at all since
retriggering the startup sequence and selftests has no side effects.

For a TPM device to be operational we need to initialize it and
perform its startup sequence. The 'tpm init' command currently calls
tpm_init() which ends up calling the ->open() per-device callback and
performs the initial hardware configuration as well as requesting
locality 0 for the caller. There no code that currently calls
tpm_init() without following up with a tpm_startup() and tpm_self_test_full()
or tpm_continue_self_test().
So let's add a 'tpm autostart' command and call tpm_auto_start() which
leaves the device in an operational state.
It's worth noting that calling tpm_init() only, doesn't allow a someone
to use the TPM since the startup sequence is mandatory. We always
repeat the pattern of calling
- tpm_init()
- tpm_startup()
- tpm_self_test_full() or tpm_continue_self_test()

In case RX error occurs, and the RD_RFE bit is set, the descriptor
is never returned back to the queue. Make sh_eth_recv_start return
zero length in this case so that the descriptor can be released
and pushed back to the list. Also return the more appropriate
-EAGAIN instead of -EINVAL if the descriptor is not ready yet.

U-Boot writes to RX packets when constructing replies.
This can cause stale cached data to be written to RX
buffer while we're receiving a packet. This causes RX
packet corruption because we invalidate the cache right
before processing the packet. Invalidate packet buffer
cache when preparing RX descriptor as well. This seems
to fix RX packet drops with high RX traffic.
While at it flush the descriptors right before enabling
RX/TX in sh_eth_tx_desc_init/sh_eth_rx_desc_init callbacks
when they are ready instead of flushing after allocation.

mtd: spi: renesas: Add 4 bytes address mode support
This patch adds 4-byte address mode support. Because traditional access
based on FIFO/shift register, it's complex to specify information like
opcode, address length, dummy bytes etc to flash. Replace the traditional
access by spi-mem layer which is essential to make 4-byte address mode
support possible.
