This adds support for setting clock rates, which was left out of the
initial CCF expunging. There are several tricky bits here, mostly related
to the PLLS:
* The PLL's bypass is broken. If the PLL is reconfigured, any child clocks
will be stopped.
* PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent
stopping the CPU while we configure PLL0's rate, ACLK is reparented
to IN0 while PLL0 is disabled.
* PLL1 is the parent of the AISRAM clock. This clock cannot be reparented,
so we instead just disallow changing PLL1's rate after relocation (when
we are using the AISRAM).

Now that there no separate PLL driver, we can no longer make the PLL
functions static. By moving the PLL driver in with the rest of the clock
code, we can make these functions static again. We still keep the pll
header for unit testing, but it is pretty reduced.

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 :)

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
commit thread about the overhead of repeatedly parsing the device tree.

At present the AE350 SPL defconfig is using OF_PRIOR_STAGE. The
intention was to use gdb to load device tree before running U-Boot
SPL/proper from RAM. When we switch to OF_SEPARATE we will have to
use our own DT but without "u-boot,dm-spl" in several essential
nodes, SPL does not boot.
Let's add all the required "u-boot,dm-spl" for SPL config.

When using bootefi to boot a EFI binary, u-boot is supposed to
provide networking service for EFI application. Currently, 'pfe stop'
command is called from bootcmd before running bootefi. As a result
network stops working for EFI applications and console is flooded with
"Rx pkt not on expected port" messages.
Implement board_quiesce_devices() for ls1012a boards and call
pfe_command_stop() from it instead of calling 'pfe stop' from
*_bootcmd and bootcmd.

It was noticed that the clock isn't continuously enabled when there is
no link. This is because the 125MHz clock is derived from the internal
PLL which seems to go into some kind of power-down mode every once in a
while. The LS1028A expects a contiuous clock. Thus enable the PLL all
the time.
Also, the RGMII pad voltage is wrong, it was configured to 2.5V (that is
the VDDH regulator). The correct voltage is 1.8V, i.e. the VDDIO
regulator.

- Turris: Fix bootcmd_rescue (Pali)
|
|
One of the points of putting the rescue boot command into default
environment is that user can invoke it without physical access to the
board (without having to press the factory reset button), by running
run bootcmd_rescue
in U-Boot's console.
Therefore we have to ensure that bootcmd_rescue is always set to default
value, regardless of whether the factory reset button was pressed.
Otherwise the variable will be empty for example after upgrade from
previous U-Boot.

This supports Falcon boot support for Microchip SAMA5D3 Xplained,
tested on raw MMC, and on raw NAND.
spl_start_uboot() is has the simplest possible implementation.
It doesn't test the environment because enabling environment support
currently causes the SPL to exceed its maximum size (64 KiB).
It doesn't check the serial for incoming characters either because
this functionality currently doesn't seem to work from the SPL
on this board.
Settings for Falcon boot from at FAT partition are also added to
avoid compile failures when CONFIG_SPL_OS_BOOT is enabled, but this
particular case is currently not functional as adding FAT and
partition support cause the SPL to be too big again.

On J721e and J7200, MCU R5 core (boot master) itself would run Device
Manager (DM) Firmware and interact with TI Foundational Security (TIFS)
firmware to enable DMA and such other Resource Management (RM) services.
So, during R5 SPL stage there is no such RM service available and ti_sci
driver will have to directly interact with TIFS using DM to DMSC
channels to request RM resources.
Therefore add DT binding and driver for the same. This driver will

MCU timer1 is used as the tick timer for MCU R5 SPL, and the
clock-frequency defined in DT appears to be incorrect at the moment.
Actual clock source for the timer is MCU_SYSCLK0 / 4 which is 250MHz.
Earlier setup of 25MHz went unnoticed, as there was a separate issue
with omap-timer, which caused an error to the clock by a factor of 8
with j7 devices. This problem surfaced once the omap-timer was fixed.
