44103cf331 colibri_imx6: fix RALAT and WALAT values
Running a memtest in U-Boot and Linux shows that some Colibri iMX6
produce bitflips at temperatures above 60°C. This happens because the
RALAT and WALAT values on the Colibri iMX6 are too low. The problems
were introduced by commit 09dbac8174 ("mx6: ddr: Restore ralat/walat
in write level calibration") before the calibration process overwrote
the values and set them to the maximum value. With this commit, we make
sure that the RALAT and WALAT values are set to the maximum values
again. This has been proven to work for years.

55c0144bd3 spi: bcmbca-hsspi: Add driver for newer HSSPI controller
The newer BCMBCA SoCs such as BCM6756, BCM4912 and BCM6855 include an
updated SPI controller that add the capability to allow the driver to
control chip select explicitly. Driver can control and keep cs low
between the transfers natively. Hence the dummy cs workaround or prepend
mode found in the bcm63xx-hsspi driver are no longer needed and this new
driver is much cleaner.

0e144ec38c spi: bcm63xx-hsspi: Add prepend mode support
Due to the controller limitation to keep the chip select low during the
bus idle time between the transfer, a dummy cs workaround was used when
this driver was first upstreamed to the u-boot based on linux kernel
driver. It basically picks the dummy cs as !actual_cs so typically dummy
cs is 1 when most of the case only cs 0 is used in the board design.
Then invert the polarity of both cs and tell the controller to start the
transfers using dummy cs. Assuming both cs are active low before the
inversion, effectively this keeps dummy cs high and actual cs low during
the transfer and workaround the issue.

This workaround requires that dummy cs 1 pin to is set to SPI chip
selection function in the pinmux when the transfer clock is above 25MHz.
The old chips likely have default pinmux set to chip select on the dummy
cs pin so it works but this is not case for the new Broadband BCA chips
and this workaround stop working. This is specifically an issue to
support SPI NAND and SPI NOR flash because these flash devices can
typically run at or above 100MHz.

This patch utilizes the prepend feature of the controller to combine the
multiple transfers in the same message to a single transfer when
possible. This way there is no need to keep clock low between transfers
and solve the issue without any pinmux requirement.

Multiple transfers within a SPI message may be combined into one
transfer if the following are all true:
  * One or more half duplex write transfer in single bit mode
  * Optional full duplex read/write at the end
  * No delay and cs_change between transfers

Most of the SPI device meets this requirements such as SPI NOR, SPI NAND
flash, Broadcom SPI voice card and etc. So this change switches to the
prepend mode as the default mode. For any SPI message that does not meet
the above requirement, we switch to original dummy cs mode but limit the
clock rate to the safe 25MHz.

Currently the driver always sets the controller to dual data bit mode
for both tx and rx data in the profile mode control register even for
single data bit transfer. Luckily the opcode is set correctly according
to SPI transfer data bit width so it does not actually cause issues.

This change fixes the problem by setting tx and rx data bit mode field
correctly according to the actual SPI transfer tx and rx data bit width.

The CN9130 SoC (an ARMADA 8K type) has both a NAND Flash Controller and
a generic local bus controller (Device Bus Controller) that share common
pins.

With a board design that incorporates both a NAND flash and uses
the Device Bus (in our case for an SRAM) accessing the Device Bus device
fails unless the NfArbiterEn bit is set. Setting the bit enables
arbitration between the Device Bus and the NAND flash.

Since there is no obvious downside in enabling this for designs that
don't require arbitration, we always enable it.

9675d92027 riscv: Rename SiFive CLINT to RISC-V ALINT
As the RISC-V ACLINT specification is defined to be backward compatible
with the SiFive CLINT specification, we rename SiFive CLINT to RISC-V
ALINT in the source tree to be future-proof.

7f1a30fdeb riscv: clint: Update the sifive clint ipi driver to support aclint
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.
