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.

Port from linux patch:

4daa6bb6f7 spi: aspeed: Add ASPEED SPI controller driver
Add ASPEED BMC FMC/SPI memory controller driver with
spi-mem interface for AST2500 and AST2600 platform.

There are three SPI memory controllers embedded in an ASPEED SoC.
- FMC: Named as Firmware Memory Controller. After AC on, MCU ROM
       fetches initial device boot image from FMC chip select(CS) 0.

- SPI1: Play the role of a SPI Master controller. Or, there is a
        dedicated path for HOST(X86) to access its BIOS flash mounted
        under BMC. spi-aspeed-smc.c implements the control sequence when
        SPI1 is a SPI master.

- SPI2: It is a pure SPI flash controller. For most scenarios, flashes
        mounted under it are for pure storage purpose.

ASPEED SPI controller supports 1-1-1, 1-1-2 and 1-1-4 SPI flash mode.
Three types of command mode are supported, normal mode, command
read/write mode and user mode.
- Normal mode: Default mode. After power on, normal read command 03h or
               13h is used to fetch boot image from SPI flash.
               - AST2500: Only 03h command can be used after power on
                          or reset.
               - AST2600: If FMC04[6:4] is set, 13h command is used,
                          otherwise, 03h command.
               The address length is decided by FMC04[2:0].

- Command mode: SPI controller can send command and address
                automatically when CPU read/write the related remapped
                or decoded address area. The command used by this mode
                can be configured by FMC10/14/18[23:16]. Also, the
                address length is decided by FMC04[2:0]. This mode will
                be implemented in the following patch series.

- User mode: It is a traditional and pure SPI operation, where
             SPI transmission is controlled by CPU. It is the main
             mode in this patch.

Each SPI controller in ASPEED SoC has its own decoded address mapping.
Within each SPI controller decoded address, driver can assign a specific
address region for each CS of a SPI controller. The decoded address
cannot overlap to each other. With normal mode and command mode, the
decoded address accessed by the CPU determines which CS is active.
When user mode is adopted, the CS decoded address is a FIFO, CPU can
send/receive any SPI transmission by accessing the related decoded
address for the target CS.

This patch only implements user mode initially. Command read/write
mode will be implemented in the following patches.

This patch adds support for the Rockchip serial flash controller
found on the PX30 SoC. It should work for versions 3-5 of the SFC
IP, however I am only able to test it on v3.

This is adapted from the WIP SPI-MEM driver for the SFC on mainline
Linux. Note that the main difference between this and earlier versions
of the driver is that this one does not support DMA. In testing
the performance difference (performing a dual mode read on a 128Mb
chip) is negligible. DMA, if used, must also be disabled in SPL
mode when using A-TF anyway.

Deadline for DM migration already passed by months

the nondm code.

Note: Look like there is no user for nondm code

383fded70c spi: nxp_fspi: new driver for the FlexSPI controller
This is a port of the kernel's spi-nxp-fspi driver. It uses the new
spi-mem interface and does not expose the more generic spi-xfer
interface. The source was taken from the v5.3-rc3 tag.

The port was straightforward:
 - remove the interrupt handling and the completion by busy polling the
   controller
 - remove locks
 - move the setup of the memory windows into claim_bus()
 - move the setup of the speed into set_speed()
 - port the device tree bindings from the original fspi_probe() to
   ofdata_to_platdata()

There were only some style change fixes, no change in any logic. For
example, there are busy loops where the return code is not handled
correctly, eg. only prints a warning with WARN_ON(). This port
intentionally left most functions unchanged to ease future bugfixes.

This was tested on a custom LS1028A board. Because the LS1028A doesn't
have proper clock framework support, changing the clock speed was not
tested. This also means that it is not possible to change the SPI
speed on LS1028A for now (neither is it possible in the linux driver).

e8ac6ffe04 x86: spi: Don't enable SPI_FLASH_BAR by default
We don't normally need this on x86 unless the size of SPI flash devices is
larger than 16MB. This can be enabled by particular SoCs as needed, since
it adds to code size.

Drop the default enabling of this option on x86.
