12507a2d22 pci: Map bars with offset and length
Evolve dm_pci_map_bar() to include an offset and length parameter. These
allow a portion of the memory to be mapped and range checks to be
applied.

Passing both the offset and length as zero results in the previous
behaviour and this is used to migrate the previous callers.

The FIU supports single, dual or quad communication interface.
The FIU controller driver provides flash access in UMA(User
Mode Access) mode by using an indirect address/data mechanism.

4de720e98d Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.

The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).

bae4d9fbd9 spi: dw: Actually mask interrupts
The designware spi driver unconditionally uses polling.

The comment to spi_hw_init() also states that the function should disable
interrupts.

According to the DesignWare DW_apb_ssi Databook, value 0xff in IMR enables
all interrupts. Since we want to mask all interrupts write 0x0 instead.

On the canaan k210 board, pressing the reset button twice to reset the
board will run u-boot. If u-boot boots Linux without having SPI interrupts
masked, Linux will hang as soon as interrupts are enabled, because of an
interrupt storm.

Properly masking the SPI interrupts in u-boot allows us to successfully
boot Linux, even after resetting the board.

The Canaan Kendryte K210 SoC DW apb_ssi v4 spi controller is documented
to have a 32 word deep TX and RX FIFO, which spi_hw_init() detects.
However, when the RX FIFO is filled up to 32 entries (RXFLR = 32), an

fifo_len to 31.

fd426b3106 k210: use the board vendor name rather than the marketing name
"kendryte" is the marketing name for the K210 RISC-V SoC produced by
Canaan Inc. Rather than "kendryte,k210", use the usual "canaan,k210"
vendor,SoC compatibility string format in the device tree files and
use the SoC name for file names.
With these changes, the device tree files are more in sync with the
Linux kernel DTS and drivers, making uboot device tree usable by the
kernel.

d56dfc90c7 spi: dw: Fix broken dw_spi_mem_ops()
The driver is currently using sizeof(op->cmd.opcode) in the op_len
calculation. Commit d15de62301 ("spi: spi-mem: allow specifying a
command's extension") changed op->cmd.opcode from one byte to two.

Instead, a new struct member op->cmd.nbytes is supposed to be used.
For regular commands op->cmd.nbytes will be one.

Commit d15de62301 ("spi: spi-mem: allow specifying a command's
extension") did update some drivers that overload the generic mem_ops()
implementation, but forgot to update dw_spi_mem_ops().

Calculating op_len incorrectly causes dw_spi_mem_ops() to misbehave, since
op_len is used to determine how many bytes that should be read/written.

On the canaan k210 board, this causes the probe of the SPI flash to fail.

Fix the op_len calculation in dw_spi_mem_ops(). Doing so results in
working SPI flash on the canaan k210 board.

765afe7fb3 spi: fsl_dspi: add new compatible fsl, ls1021a-v1.0-dspi
The official ls1028a binding of the driver uses the following as
compatibles:
  compatible = "fsl,ls1028a-dspi", "fsl,ls1021a-v1.0-dspi";

Add the missing compatible to the driver and update the device tree.
We can use the fallback "fsl,ls1021a-v1.0-dspi", because the endianness
is determined by the little-endian property and not by the compatible
string itself. Further, we won't need and specific details on the DMA
configuration (which is different on the LS1021A). If it's ever needed,
we can later add the more specific "fsl,ls1028a-dspi" compatible to the
driver.

4f9d25537c spi: zynqmp_gqspi: Fix write issue at low frequencies
With current implementation we are seeing write issues at low frequencies
below 15Mhz. Make below changes to fix the issue.

1. Remove dummy genfifo entry in zynqmp_qspi_chipselect() which was
   incorrectly added in the past

2. Enable and poll for TX_FIFO_Empty after Tx data is filled in FIFO in
   zynqmp_qspi_fill_tx_fifo().

b9cfd8b091 spi: nxp_fspi: Implement errata workaround for LS1028A
Errata ERR050568 description says that "Flash access by FlexSPI AHB
command may not work with platform frequency equal to 300 MHz" on
LS1028A.

By default, smaller length reads(equal to RX FIFO size) are done by IP
bus and larger length reads using AHB bus. For adding errata workaround,
use IP bus to read entire flash contents and disable AHB path when
platform frequency is 300Mhz.

e8751a9387 spi: nxp-fspi: Add support for IP read only
Add support for disabling AHB bus and read entire flash contents via IP
bus only. Please note, this enables IP bus read using a quirk which can
be enabled directly in device-type data or in existence of an errata
where AHB bus may need to be disabled.

4d9958b642 sunxi: gpio: Remove name_to_gpio macro
This clarifies which callers must be updated to complete the DM_GPIO
conversion.

The only remaining caller of name_to_gpio in generic code is inside the
!DM_GPIO block in cmd/gpio.c. DM_GPIO is always selected on sunxi, so
that code cannot be reached. And after this commit, there are only two
remaining implementations of name_to_gpio.

c2e0363571 mtd: cqspi: Fix division by zero
Both dummy.nbytes and dummy.buswidth may be zero. By not checking
the later, it is possible to trigger division by zero and a crash.
This does happen with tiny SPI NOR framework in SPL. Fix this by
adding the check and returning zero dummy bytes in such a case.
