In U-Boot, the discovery of TA based on its UUID on the TEE bus is
not supported.
This patch only binds the driver associated to the new supported
OP-TEE TA = TA_HWRNG when this driver is enable.

Add driver for OP-TEE based Random Number Generator on ARM SoCs
where hardware entropy sources are not accessible to normal world
and the RNG service is provided by a HWRNG Trusted Application (TA).
This driver is based on the linux driver: char/hw_random/optee-rng.c

To quote the author:
This series adds support for running valgrind against U-Boot's internal
malloc. This allows for much more useful reports to be generated.
Some example output of valgrind run against u-boot/master with this
branch applied may be found at [1]. Note that valgrind gives up around
acpi. This feature still needs a lot of work on suppressions/hints to
filter out the noise properly.

This documents how to get more detailed results from valgrind made possible
by the last two commits.

This annotates malloc and friends so that valgrind can track the heap. To
do this, we need to follow a few rules:
* Call VALGRIND_MALLOCLIKE_BLOCK whenever we malloc something
* Call VALGRIND_FREELIKE_BLOCK whenever we free something (generally after
we have done our bookkeeping)
* Call VALGRIND_RESIZEINPLACE_BLOCK whenever we change the size of an
allocation. We don't record the original request size of a block, and
neither does valgrind. For this reason, we pretend that the old size of
the allocation was for 0 bytes. This marks the whole allocaton as
undefined, so in order to mark all bits correctly, we must make the whole
new allocation defined with VALGRIND_MAKE_MEM_DEFINED. This may cause us
to miss some invalid reads, but there is no way to detect these without
recording the original size of the allocation.
In addition to the above, dlmalloc itself tends to make a lot of accesses
which we know are safe, but which would be unsafe outside of dlmalloc. For
this reason, we provide a suppression file which ignores errors ocurring in
dlmalloc.c

Valgrind uses magic code sequences to define an ABI that the client may use
to request behavior from the host. In particular, this may be used to
inform valgrind about custom allocators, such as the one used in U-Boot.
This adds headers defining these sequences to U-Boot. It also adds a config
option to disable emission of these sequences entirely, in the (likely)
event that the user does not wish to use valgrind. Note that this option is
called NVALGRIND upstream, but was renamed (and inverted) to
CONFIG_VALGRIND. Aside from this and the conversion of a few instances of
VALGRIND_DO_CLIENT_REQUEST_EXPR to STMT, these headers are unmodified.
These headers were copied from valgrind 3.16.1-4 as distributed in Arch
Linux. They are licensed with the bzip2 1.16 license. This appears to be a
BSD license with some clauses from Zlib.

This reverts commit 8d61237edb.
This commit broke environment on literally every board I have access
to, with this revert in place, environment works as it should again.
The problem I observe with this patch is that saved environment in
either SPI NOR or eMMC is never used, the system always falls back
to default environment. The 'saveenv' command does succeed, but then
after reset, the default env is again used.
Furthermore, the commit introduced duplicate code in env_init(), this:
"
if (!prio) {
gd->env_addr = (ulong)&default_environment[0];
gd->env_valid = ENV_INVALID;
return 0;
}
if (ret == -ENOENT) {
gd->env_addr = (ulong)&default_environment[0];
gd->env_valid = ENV_INVALID;
return 0;
}
"
Furthermore, the commit is missing DCO SoB line.
Also note that upstream does not support UltraZed EG board, so
this might have been a patch pulled from downstream which did
depend on some other downstream behavior.

virtio_init() enumerates all the peripherals that are to be materialised
with udevices(UCLASS_VIRIO) and creates particular device instances
(UCLASS_BlK or whatever else) as children.
On the other hand, device_probe() won't be invoked against those resultant
udevices unlike other ordinary device drivers do in the driver model.
This is particularly inconvenient when we want to add "event notification"
callback so that we will be able to automatically create all efi_disk
objects in a later patch.
With this patch applied, "virtio scan" will work in a similar way
to "scsi rescan", "usb start" or others in term of 'probe' semantics.
I didn't add this change to virtio_init() itself because this function
may be called in board_init_r() (indirectly in board_late_init())
before UEFI subsustem is initialized.
