This copies the cpu_call64() function to memory address and then jumps to
it. This seems to work correctly even when called from SPL, which is
running from SPI flash.
Drop the copy as it is not needed.

We don't need to commit the SPI-flash MTRR change immediately, since it is
now done in the board_init_f_r(). Also this causes chromebook_link64 to
hang, presumably since we are still running from CAR (Cache-as-RAM) in
SPL. Coral handles this OK, perhaps since it is running from a different
memory area, but it has no effect on Coral anyway.
Drop the extra mtrr_commit() in the SPL implementation.

This function is used by U-Boot proper. It does not set up MTRRs when SPL
is enabled, but we do want this done when it is called from SPL. In fact
it is confusing to use the same function from SPL, since there are quite
a few conditions there.
All init_cache_f_r() really does is commit the MTRRs and set up the cache.
Do this in the SPL's version of this function instead.

Use the binman symbols for this, to avoid hard-coding the value. We could

The original function was only called once, before relocation. The new
one is called again after relocation. This was not the intent of the
original call. Fix this by renaming and updating the calling logic.

When running the EFI app, we need to exit boot services before jumping
to Linux.
At some point it may be possible to jump to Linux and pass on the system
table, and:
* install the device-tree as configuration table
* use LoadImage() to load the kernel image (e.g. from memory)
* start the image with StartImage()
This should allow the Linux efistub to be used. For now, this is not

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.
With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.
