There used to be blank lines between assignment and check of the
__of_changeset_revert_entries() result, to make the phandle cache
management operations stand out. After the removal of those operations
in commit 90dc0d1ce890419f ("of: Rework and simplify phandle cache to
use a fixed size"), there is no longer a reason to have such a blank
line.
Remove the blank line, to rejoin visibly the status assignement and
check, and to match coding style.

Fix up inconsistent usage of upper and lowercase letters in "Exynos"
name.
"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

"disable-wp" has been removed from all Rockchip eMMC and SDIO dts nodes,
but people still continue to submit new patches with "disable-wp" added
to other nodes then for the SD card slot,
what it was designed for in the first place.
So clarify the "disable-wp" text by adding that this option should
not be used in combination with eMMC or SDIO.

The phandle cache was added to speed up of_find_node_by_phandle() by
avoiding walking the whole DT to find a matching phandle. The
implementation has several shortcomings:
- The cache is designed to work on a linear set of phandle values.
This is true for dtc generated DTs, but not for other cases such as
Power.
- The cache isn't enabled until of_core_init() and a typical system
may see hundreds of calls to of_find_node_by_phandle() before that
point.
- The cache is freed and re-allocated when the number of phandles
changes.
- It takes a raw spinlock around a memory allocation which breaks on
RT.
Change the implementation to a fixed size and use hash_32() as the
cache index. This greatly simplifies the implementation. It avoids
the need for any re-alloc of the cache and taking a reference on nodes
in the cache. We only have a single source of removing cache entries
which is of_detach_node().
Using hash_32() removes any assumption on phandle values improving
the hit rate for non-linear phandle values. The effect on linear values
using hash_32() is about a 10% collision. The chances of thrashing on
colliding values seems to be low.
To compare performance, I used a RK3399 board which is a pretty typical
system. I found that just measuring boot time as done previously is
noisy and may be impacted by other things. Also bringing up secondary
cores causes some issues with measuring, so I booted with 'nr_cpus=1'.
With no caching, calls to of_find_node_by_phandle() take about 20124 us
for 1248 calls. There's an additional 288 calls before time keeping is
up. Using the average time per hit/miss with the cache, we can calculate
these calls to take 690 us (277 hit / 11 miss) with a 128 entry cache
and 13319 us with no cache or an uninitialized cache.
Comparing the 3 implementations the time spent in
of_find_node_by_phandle() is:
no cache: 20124 us (+ 13319 us)
128 entry cache: 5134 us (+ 690 us)
current cache: 819 us (+ 13319 us)
We could move the allocation of the cache earlier to improve the
current cache, but that just further complicates the situation as it
needs to be after slab is up, so we can't do it when unflattening (which
uses memblock).

Even though the generic mmio-sram binding has a list of the sections

This creates warnings at the moment, and we don't really want to cripple

prove to be hard to maintain.
Let's allow additional compatibles for the sections, and then we can have
the vendor-specific bindings to reduce the scope of what's allowed exactly.
