not all flashes support SFDP in 8D-8D-8D mode.

Further, even if you detect the mode of the flash via SFDP, you still
have the problem of actually reading the ID. The Read ID command is not
standardized across flash vendors. Flashes can have different dummy
cycles needed for reading the ID. Some flashes even expect a 4-byte
dummy address with the Read ID command. All this information cannot be

default protocol mode assuming no non-volatile configuration was set.

The hooks and at what points they are executed mimics Linux's spi-nor
framework. One major difference is that Linux puts the struct
spi_nor_fixups in nor->info. This is not possible in U-Boot because the
spi-nor-ids list is shared between spi-nor-core.c and spi-nor-tiny.c.

separate function that lets flashes populate their fixup hooks.

Set up opcode extension and enable/disable DTR mode based on whether the
command is DTR or not.

xSPI flashes can have a 4-byte dummy address associated with some
commands like the Read Status Register command in octal DTR mode. Since
the flash does not support sending the dummy address, we can not use
automatic write completion polling in DTR mode. Further, no write
completion polling makes it impossible to use DAC mode for DTR writes.
In that mode, the controller does not know beforehand how long a write
will be and so it can de-assert Chip Select (CS#) at any time. Once CS#
is de-assert, the flash will go into burning phase. But since the
controller does not do write completion polling, it does not know when
the flash is busy and might send in writes while the flash is not ready.

So, disable write completion polling and make writes go through indirect
mode for DTR writes and let spi-mem take care of polling the SR.

The get_mtd_device_nm() function (code imported from Linux) simply
iterates all registered MTD devices and compares the given name with
all MTDs' names.

With SPI_FLASH_MTD enabled U-Boot registers a SPI-NOR as a MTD device
with name identical to the SPI flash chip name (from SPI ID table). Thus
for a board with multiple same SPI-NORs it registers multiple MTDs, but
all with the same name (such as "s25fl164k"). We do not want to change
this behaviour, since such a change could break existing boot scripts,
which can rely on a hardcoded name.

In order to allow somehow to uniqely select a MTD device, change
get_mtd_device_nm() function as such:
- if first character of name is '/', try interpreting it as OF path
- otherwise compare the name with MTDs name and MTDs device name.

In the following example a board has two "s25fl164k" SPI-NORs. They both
have name "s25fl164k", thus cannot be uniquely selected via this name.
With this change, the user can select the second SPI-NOR either with
"spi-nor@1" or "/soc/spi@10600/spi-nor@1".

Example:
  => mtd list
  List of MTD devices:
  * s25fl164k

clk: k210: Rewrite to remove CCF

This is effectively a complete rewrite to remove all dependency on CCF.
The code is now smaller, and so is the binary. It also takes up less memory
at runtime (since we don't have to create 40 udevices). In general, I am
much happier with this driver as much of the complexity and late binding
has been removed.

The k210_*_params structs which were previously used to initialize CCF
clocks are now used as the complete configuration. Since we can write our
own division logic, we can now do away with several "half" clocks which
only existed to provide constant factors of two.

The clock IDs have been renumbered to remove unused clocks. This may not be
the last time they are renumbered, since we have diverged with Linux. There
are also still a few clocks left out which may need to be added back in.

In general, I have tried to leave out behavioral changes. However, there is
a small bugfix regarding ACLK. According to the technical reference manual,
its mux comes *after* its divider (which is present only for PLL0). This
would have required yet another intermediate clock to fix with CCF, but
with the new driver it is just 2 lines of code :)

clk: Allow force setting clock defaults before relocation

Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc
state for SPL only") it has been impossible to set clock defaults before
relocation. This is annoying on boards without SPL, since there is no way
to set clock defaults before U-Boot proper. In particular, the aisram rate
must be changed before relocation on the K210, since U-Boot will hang if we
try and change the rate while we are using aisram.

To get around this, extend the stage parameter to allow force setting
defaults, even if they would be otherwise postponed for later. A device
tree property was decided against because of the concerns in the original
