rockchip: sdhci: Fix RK3399 eMMC PHY power cycling

The Rockchip RK3399 eMMC PHY has to be power-cycled while changing its
clock speed to some higher speeds. This is dependent on the desired
SDHCI clock speed, and it looks like the PHY should be powered off while
setting the SDHCI clock in these cases.

Commit ac804143cfd1 ("mmc: rockchip_sdhci: add phy and clock config for
rk3399") attempts to do this in the set_ios_post() hook by setting the
SDHCI clock once more while the PHY is turned off/on as necessary, as
the SDHCI framework does not provide a way to override how it sets its
clock. However, the commit breaks reinitializing the eMMC on a few
boards including chromebook_kevin and reportedly ROCKPro64.

This patch reworks the power cycling to utilize the SDHCI framework
slightly better (using the set_control_reg() hook to power off the PHY
and set_ios_post() hook to power it back on) which happens to fix the

Merge branch '2022-03-09-events-subsystem' into next

To quote the author:
It is a common need in U-Boot to have one subsystem notify another
when something happens. An example is reading a partition table when a
new block device is set up.

It is also common to add weak functions and 'hook' functions to modify
how U-Boot works. See for example ft_board_setup() and the like.

U-Boot would benefit from a generic mechanism to handle these cases,
with the ability to hook into various 'events' in a
subsystem-independent and transparent way.

This series provides a way to create and dispatch events, with a way of
registering a 'spy' which watches for events of different types. This
allows 'hook' functions to be created in a generic way.

It also includes a script to list the hooks in an image, which is a bit
easier to debug than weak functions, as well as an 'event' command to
do the same from within U-Boot.

These 'static' events can be used to replace hooks like misc_init_f(),
for example. Also included is basic support for 'dynamic' events, where
a spy can be registered at runtime. The need for this is still being
figured out.

sunxi: boards: Enable SPI flash support in U-Boot proper

Some sunxi boards ship with SPI flash, which allows booting through the
BootROM. We cover this functionality by a separate SPL "mini" driver.
Separately we have a proper DM_SPI driver for U-Boot proper, which
provides access to the SPI flash through the "sf" command. That allows
to update the firmware on the SPI flash, also to store the environment
there.

However only very few boards actually enable support for U-Boot proper,
even though that would work and the SPL part is configured.

Use the cleaned up configuration scheme to enable SPI flash on those
boards which mention a SPI flash in their .dts, or which use the SPL SPI
support.

Out of the box this would enable storing the environment on the SPI
flash, and allows people to read or write the flash from U-Boot, for
instance to update the SPI flash when booted via an SD card.

For this to actually work there must be a "spi0" alias in the DT, which
most boards are missing. But this should be addressed separately.

also want to support using the environment there, so we need to become
a bit more flexible.

Change the environment priority function to take the boot source into
account. When booted from eMMC or SD card, we use FAT or MMC, if
configured, as before.
If we are booted from SPI flash, we try to use the environment from
there, if possible. The same is true for NAND flash booting, although
this is somewhat theoretical right now (as untested).

This way we can use the same image for SD and SPI flash booting, which

U-Boot (including SPL and other blobs) is loaded from the beginning of
SPI flash, so move the environment location as far back as possible, to
not create unnecessary limits. As those offsets are shared with (now
mostly unused) raw MMC environment, we should respect the common one
megabyte limit, which also makes sense on SPI flash.

So limit the environment for those raw locations to 64KB, and place it
just below 1MB (@960KB).

Those values are currently unused, unless someone forcibly enables the
raw MMC environment. In this case it would break as of now, as the
