Commit 72443c7f7d ("mtd: cfi: Add support for status register
polling") added a feature check to determine if status register
is available for certain flash chips. The "lower software bits"
register used to determine this feature is not backward compati-
ble. Older flash chips without this feature has reserved value
0xff. Instead of checking "lower software bits" register, use
CFI primary vendor-specific extended query. Since CFI version
1.4, software features can be read from offset 0x53 according to
document AN201168 from Cypress.

The u-boot.sym file is scanned to find unit test suites for execution. At
present it only finds those whose names start with 'dm' or 'env'. This
code is buried in the bowels of the test code so when adding a new suite
it is not easy to discover why it is ignored by the test framework.
There seems to be no need to make this restriction. Drop it.

At present the test setup is somewhat mixed with the test itself. But if
the test setup fails (which it should not) then the test is actually
invalid. Put all the test buffers and sizes in a struct and separate out
the core code into a function.
This will make it easier to move the code to use the unit test framework.

The kernel gets the ethernet MAC from the ethaddr variable, the omap boards for
devices with USB based eth adapters just set the usbethaddr which doesn't appear
to get passed to the kernel. The same Raspberry Pi code sets both ethaddr and
usbethaddr so lets do that so linux (tested 4.13 and 4.14) get a static rather
than a random MAC address, while not regressing users of usbethaddr.

Depending on your compiler, when compiling the hello world efi binary
with -Os, gcc might think it's a smart idea to replace common patterns
such as memory copies with explicit calls to memcpy().
While that sounds great at first, we don't have any memcpy() available
in our helloworld build target. So let's indicate to gcc that we really
do want to have the code be built as freestanding.

Commit 884bcf6f65 (efi_loader: use proper device-paths for partitions) tried
to introduce the el torito scheme to all partition table types: Spawn
individual disk objects for each partition on a disk.
Unfortunately, that code ended up creating partitions with offset=0 which meant
that anyone accessing these objects gets data from the raw block device instead
of the partition.
Furthermore, all the el torito logic to spawn devices for partitions was
duplicated. So let's merge the two code paths and give partition disk objects
good offsets to work from, so that payloads can actually make use of them.

This is required so that efi_dp_match() will work as expected
when doing memcmp() comparisons. Previously uninitialised memory
would cause it not match nodes when it should have when the signature
type was not GUID.
