This RISC-V ACLINT specification [1] defines a set of memory mapped
devices which provide inter-processor interrupts (IPI) and timer
functionalities for each HART on a multi-HART RISC-V platform.
The RISC-V ACLINT specification is defined to be backward compatible
with the SiFive CLINT specification, however the device tree binding
is a new one. This change updates the sifive clint ipi driver to
support ACLINT mswi device, by checking the per-driver data field of
the ACLINT mtimer driver to determine whether a syscon based approach
needs to be taken to get the base address of the ACLINT mswi device.

The main difference between StarFive VisionFive 2 1.2A and 1.3B is gmac.
You can read the PCB version of the current board by
get_pcb_revision_from_eeprom(), and then dynamically configure the
difference of gmac in spl_perform_fixups() according to different PCB
versions, so that one DT and one defconfig can support both 1.2A and
1.3B versions, which is more user-friendly.

StarFive VisionFive 2 has two versions, 1.2A and 1.3B, each version of
DDR capacity includes 2G/4G/8G, a DT can not support multiple
capacities, so the capacity size information is recorded to EEPROM, when
DDR initialization required capacity size information is read from
EEPROM.
If there is no information in EEPROM, it is initialized with the default
size defined in DT.

While testing the ethernet interface on a Variscite symphony carrier
board using an imx8mn SOM with an onboard ADIN1300 PHY (EC hardware
configuration), the ethernet PHY is not detected.
The ADIN1300 datasheet indicate that the "Management interface
active (t4)" state is reached at most 5ms after the reset signal is
deasserted.
The device tree in Variscite custom git repository uses the following
property:
phy-reset-post-delay = <20>;
Add a new MDIO property 'reset-deassert-us' of 20ms to have the same
delay inside the ethphy node. Adding this property fixes the problem
with the PHY detection.
Note that this SOM can also have an Atheros AR8033 PHY. In this case,
a 1ms deassert delay is sufficient. Add a comment to that effect.

Before this change the FR_TXFF (Transmit FIFO full) bit (5 in
HW_UARTDBG_FR) has been used to assess if there is still data pending
to be sent via UART.
This approach is problematic, as it may happen that serial is in the
middle of transmission (so the TX FIFO is NOT full anymore) and this
test returns true infinitely. As a result, for example in _serial_flush()
DM serial function we are locked in endless while().
The fix here is to test explicitly if the TX FIFO is empty.

The DM_SERIAL implicitly requires CONFIG_PL01X_SERIAL, which
allows support for both serial IP block versions (i.e. PL011 and
PL010).
The decision about used IP block is based on the compatible string,
when DM is used.
In the XEA, the OF_PLATDATA is used to allow usage of serial driver in
the SPL (as the size of SPL is crucial). In this case one cannot extract
the type of IP block from .data field (corresponding to compatible) and
it must be explicitly read at probe from dtoc generated, u-boot specific
property.
