clarifies how we decide of a tree is valid or not. We say that all
bindings must either be in the specification (link provided) or in our
device-tree-bindings directory. We say that most of these come from the
Linux Kernel and as such some design decisions are made for us already,
but that in most cases we wish to retain compatibility.

Enable CONFIG_OF_BOARD_SETUP as it is needed for Beaglebone

in case the phy latches on to a different address.

On beaglebone black, it can so happen that PHY address
is not latched correctly on reset and board boots with
PHY responding to a different address than that
programmed in device-tree. For example, see this report:
https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J
Workaround this by fixing up device-tree passed to kernel
by using the PHY address detected in hardware.
Beaglebone itself uses only one ethernet port and its DT
currently uses phy_id (obsoleted). But the function has
been written to handle multiple ports and phy_id as well
as phy-handle to make the function more generically useful.

On some boards using TI CPSW, it may be possible that
PHY address was not latched correctly, and the actual
address that the phy responds on is different from that
set in device-tree. For example, see this problem report
on beaglebone black:
https://groups.google.com/d/msg/beagleboard/9mctrG26Mc8/1FuI_i5KW10J
Add support to check for this condition and use the
detected phy address when its safe to do so.
Also, add a public API that exposes the phy address of
a given slave. This can be used to update device-tree that
is passed to Linux kernel.

The SPL loaders assume that the CONFIG_SYS_TEXT_BASE memory location
is available and can be corrupted by loading ie. uImage or fitImage
headers there. Sometimes it could be beneficial to load the headers
elsewhere, ie. if CONFIG_SYS_TEXT_BASE is not yet writable while we
still want to parse the image headers in some local onchip memory to
ie. extract firmware from that image.
Add the possibility to override the location where the headers get
loaded by introducing new function, spl_get_load_buffer() which takes
two arguments -- offset from the CONFIG_SYS_TEXT_BASE and size of the
data that are to be loaded there -- and returns a valid buffer address
or hangs the system. The default behavior is the same as before, add
the offset to CONFIG_SYS_TEXT_BASE and return that address. User can
override the weak spl_get_load_buffer() function though.

In sandbox, longjmp returns to itself in an endless loop because
os_longjmp() calls into longjmp() which is provided by U-Boot which
again calls os_longjmp().
Setjmp on the other hand must not return because otherwise the
return freees up stack elements that we need during longjmp().
The only straight forward fix that doesn't involve nasty hacks I
could find is to directly link against the system setjmp/longjmp
implementations. That means we just provide the compiler with
hints that the symbol will be available and actually fill them
out with versions from libc.

At present map_sysmem() maps an address into the sandbox RAM buffer,
return a pointer, while map_to_sysmem() goes the other way.
The mapping is currently just 1:1 since a case was not found where a more
flexible mapping was needed. PCI does have a separate and more complex
mapping, but uses its own mechanism.
However this arrange cannot handle one important case, which is where a
test declares a stack variable and passes a pointer to it into a U-Boot
function which uses map_to_sysmem() to turn it into a address. Since the
pointer is not inside emulated DRAM, this will fail.
Add a mapping feature which can handle any such pointer, mapping it to a
simple tag value which can be passed around in U-Boot as an address.
