This patchset adds initial support for the Exynos 5515 SoC, along with
support for the Samsung Galaxy Watch FE (codenamed lucky7), which uses
this SoC.

Support for the following is added:
- Bootloader framebuffer
- Both CPU cores
- Memory
- Generic timer
- Watchdog timer
- CMU_TOP, CMU_FSYS, CMU_PERI clock management units
- ChipID

Only the lowest 490MiB and highest 512MiB of memory are used for now.
The 488MiB between the addresses of 0x9ea00000 and 0xbe680000 is excluded
from the memory node due to a bug where if the kernel even knows about
the existence of this memory, one or both cores will lock up and cause
an RCU stall. There are several regions between this addresses which will
lock up the core, so the issue is difficult to bisect, and attempting to
dump memory information on panic will just lock up the second core.

Currently, these device trees support booting the device to an initramfs.

I am getting checkpatch warnings on this patchset advising to check
MAINTAINERS as new files were added, but I assume they can be ignored
as I am not a maintainer.

This patchset depends on [1], [2], and [3], for drivers and device tree
bindings.

You already sent a thread called "Hi there,". One is enough. Please name
cover letters correctly, so it won't get messed in our mailboxes.

Sorry about that. First time using b4 and a mailing list for patch
submissions, and I failed to notice the missing subject.
Will fix in v2 as I have issues Sashiko picked up to fix anyways.
