mpc8xxx_spi: put max_cs to use
Currently, max_cs is write-only; it's just set in
mpc8xxx_spi_ofdata_to_platdata and not otherwise used.
My mpc8309 was always resetting during an "sf probe 0". It turns out
dm_gpio_set_dir_flags() was being called with garbage, since nothing
had initialized priv->gpios[0] - our device tree used "cs-gpios"
rather than "gpios", so gpio_request_list_by_name() had returned 0.
That would have been a lot easier to figure out if the chip select
index was sanity checked, so rename max_cs to cs_count, and reject a
xfer with a too large cs index.

gpio/mpc83xx_spisel_boot.c: gpio driver for SPISEL_BOOT signal
Some SoCs in the mpc83xx family, e.g. mpc8309, have a dedicated spi
chip select, SPISEL_BOOT, that is used by the boot code to boot from
flash.
This chip select will typically be used to select a SPI boot
flash. The SPISEL_BOOT signal is controlled by a single bit in the
SPI_CS register.
Implement a gpio driver for the spi chip select register. This allows a
spi driver capable of using gpios as chip select, to bind a chip select
to SPISEL_BOOT.
It may be a little odd to do this as a GPIO driver, since the signal
is neither GP or I, but it is quite convenient to present it to the
spi driver that way. The alternative it to teach mpc8xxx_spi to handle
the SPISEL_BOOT signal itself (that is how it's done in the linux
kernel, see commit
69b921acae8a)

gpio: mpc8xxx: don't do RMW on gpdat register when setting value
The driver correctly handles reading back the value of an output gpio
by reading from the shadow register for output, and from gpdat for
inputs.
Unfortunately, when setting the value of some gpio, we do a RMW cycle
on the gpdat register without taking the shadow register into account,
thus accidentally setting other output gpios (at least those whose
value cannot be read back) to 0 at the same time.
When changing a gpio from input to output, we still need to make sure
it initially has the requested value. So, the procedure is
- update the shadow register
- compute the new gpdir register
- write the bitwise and of the shadow and new gpdir register to gpdat
- write the new gpdir register

gpio: mpc8xxx: don't modify gpdat when setting gpio as input
Since some chips don't support reading back the value of output gpios
from the gpdat register, we should not do a RMW cycle (i.e., the
clrbits_be32) on the gpdat register when setting a gpio as input, as
that might accidentally change the value of some other (still
configured as output) gpio.
The extra indirection through mpc8xxx_gpio_set_in() does not help
readability, so just fold the gpdir update into
mpc8xxx_gpio_direction_input().

Some config symbols are found in *almost* every _defconfig file for
Allwinner boards, because those options are actually a platform choice,
and not a per-board decision.
Some of these options are older, some have recently been added.
Move those options to be set for all Allwinner boards in their
respective Kconfig files.
The rationales are as follows:
- NR_DRAM_BANKS: All Allwinner SoC map DRAM at one contiguous region of
address space only, starting at 1 GB. So it's always one bank.
- SPL_{DOS,EFI}_PARTITION: The Allwinner SPL does only support raw MMC
accesses, we don't care about filesystems or partitions in there, so
there is no need to define those symbols at all.
- USE_PREBOOT: We start USB early when a keyboard is configured, using the
preboot env variable, so we need to set this variable.
- SYS_RELOC_GD_ENV_ADDR: We don't specify any ENV_ADDR, so need this
symbol to be set (according to
8d8ee47e03e).
- SYS_USB_EVENT_POLL_VIA_INT_QUEUE: According to commit
eab9433aa55428,
specifying this reduces the latency of the USB keyboard handling, so
this was formerly enabled in config headers for all Allwinner boards.

The Allwinner H6 SoC uses a quite different memory map, also changes the

which hardcodes these values so far.
Using the just introduced helper functions to determine base address
and SPI controller generation, we can cover some of these differences
easily.
The clock setup is different, so requires some explicit code changes
there (reset and clock gate in one register at a different address).
Also we need to change the pinmux function to use a different set of
pins that the H6 uses for SPI0.
Eventually we can enable the H6 to use SPI booting in Kconfig.

The H6 SoCs is the newest SoC so far, but is sufficiently different to

controller always at address 0x1c05000, and the new generation one at

the old address, and the H6 uses a completely different address.
So split off the base address from the respective SPI registers, by
changing the #defines to just contain offsets.
The base address is provided by a function, so it can easily be extended
later when support for those SoCs materialises.
This does not change the code size (since the toolchain is clever enough
to optimise this properly), also does not bring any functional change at

riscv: Introduce a new config for SBI v0.1
We now have SBI v0.2 which is more scalable and extendable to handle
future needs for RISC-V supervisor interfaces.
Introduce a new config and move all SBI v0.1 code under that config.
This allows to implement the new replacement SBI extensions cleanly
and remove v0.1 extensions easily in future. Currently, the config
is enabled by default. Once all M-mode software, with v0.1, is no
longer in use, this config option and all relevant code can be easily
removed.

riscv: Add SBI v0.2 extension definitions
Few v0.1 SBI calls are being replaced by new SBI calls that follows
v0.2 calling convention.
This patch just defines these new extensions.

riscv: Add basic support for SBI v0.2
The SBI v0.2 introduces a base extension which is backward compatible
with v0.1. Implement all helper functions and minimum required SBI
calls from v0.2 for now. All other base extension function will be
added later as per need.
As v0.2 calling convention is backward compatible with v0.1, remove
the v0.1 helper functions and just use v0.2 calling convention.
Add a new Kconfig options CONFIG_SBI for the new SBI v0.2 codes, and
let CONFIG_SBI_IPI depend on it.

riscv: Mark existing SBI as v0.1 SBI
As per the new SBI specification, current SBI implementation version
is defined as 0.1 and will be removed/replaced in future. Each of the
function call in 0.1 is defined as a separate extension which makes
easier to replace them one at a time.
Rename existing implementation to reflect that. This patch is just
a preparatory patch for SBI v0.2 and doesn't introduce any functional
changes.

riscv: Avoid calling sbi_clear_ipi()
There is no need for S-mode U-Boot to call sbi_clear_ipi() as it
can be cleared directly from S-mode. This saves some cycles.
