The 5420 clock code still had a data structure in it for the 5250 clock
registers which was used by some of the clock functions. That caused some
clocks to be configured incorrectly, specifically the i2c clock which was
running at about 80KHz instead of about 600KHz as configured by U-Boot.
Also, the registers and bit positions used to set up the SPI bus were not
consistent with U-Boot, and if the bus clock rate were set to 50MHz, a rate
which has historically worked on snow, loading would fail. With these fixes
the clock rate can be set to 50MHz and the device boots as much as is
expected. I haven't yet measured the actual frequency of the bus to verify
that it's now being calculated correctly.

The pinmux code for the exynos5250 was all bundled into a single, large
function which contained a switch statement that would set up the pins for
different peripherals within the SOC. There was also a "flags" parameter, the
meaning of which, if any, depended on which peripheral was being set up.
There are several problems with that approach. First, the code is inefficient
in both time and space. The caller knows which peripheral it wants to set up,
but that information is encoded in a constant which has to be unpacked within
the function before any action can be taken. If there were a function per
peripheral, that information would be implicit. Also, the compiler and linker
are forced to include the entire function with all its cases even if most of
them are never called. If each peripheral was a function, the unused ones
could be garbage collected.
Second, it would be possible to try to set up a peripheral which that function
doesn't know about, so there has to be additional error checking/handling. If
each peripheral had a function, the fact that there was a function to call at
all would imply that the call would be understood.
Third, the flags parameter is fairly opaque, usually doesn't do anything, and
sometimes has to have multiple values embedded in it. By having separate
functions, you can have only the parameters you actually want, give them
names that make sense, and pass in values directly.
Fourth, having one giant function pretends to be a generic, portable API, but
in reality, the only way it's useful is to call it with constants which are
specific to a particular implementation of that API. It's highly unlikely that
a bit of code will need to set up a peripheral but have no idea what that
peripheral actually is.
Call sights for the prior pinmux API have been updated. Also, pinmux
initialization within the i2c driver was moved to be in the board setup code
where it really probably belongs. The function block that implements the I2C
controller may be shared between multiple SOCs (and in fact is), and those
SOCs may have different pinmuxes (which they do).
Other places this same sort of change can be made are the pinmux code for the
5420, and the clock configuration code for both the 5250 and the 5420.

The memset and memcpy functions are assembled as ARM code, likely because
that's the default of the assembler. Without special annotation, the assembler
and linker don't know that those symbols are functions which need special
handling so that ARM/thumb issues are handled properly. This change adds that
annotation which gets those functions working in Coreboot which is compiled as
thumb. Libpayload and depthcharge are compiled as ARM so they don't *need* the
annotation since it just works out in ARM mode, but it's the safe thing to do
in case we change that in the future.
We should explicitly select ARM vs. thumb when assembling assembly files to be
