fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().
UEFI on ARM requires that unaligned memory access is enabled.
* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
For none of the other cpus in arch/arm/cpu/ we have implemented a
similar function.
* ARMv8 allows unaligned access.
Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.
Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.

The loading convention for optee or any other tee on arm64 is as bl32
parameter to the trusted-firmware. So TF-A gets invoked with the TEE as
bl32 and main u-boot as bl33. Once it has done its startup TF-A jumps
into the bl32 for the TEE startup, returns to TF-A and then jumps to bl33.
All of them get passed a devicetree as parameter and all components often
get loaded from a FIT image.
OP-TEE will create additional nodes in that devicetree namely a firmware
node and possibly multiple reserved-memory nodes.
While this devicetree is used in main u-boot, in most cases it won't be
the one passed to the actual kernel. Instead most boot commands will load
a new devicetree from somewhere like mass storage of the network, so if
that happens u-boot should transfer the optee nodes to that new devicetree.
To make that happen introduce optee_copy_fdt_nodes() called from the dt
setup function in image-fdt which after checking for the optee presence
in the u-boot dt will make sure a optee node is present in the kernel dt
and transfer any reserved-memory regions it can find.

But in the early code checking for an already existing carveout this check

so add a check there as well, which makes the function still return
successfully if a matching region is found, even though no-one wants to

(0x0000000015c19d70) have the same representation of device path.
This is not only inconvenient, but also confusing since two different
efi objects are associated with the same device path and
efi_dp_find_obj() will possibly return a wrong result.
Solution:
Each "host" device should be given an additional device path node
of "vendor device path" to make it distinguishable.

The bulk of these changes are an effort to unify Tegra186 builds with
builds of prior 64-bit Tegra generations. On top of that there are
various improvements that allow data (such as the MAC address and boot
arguments) to be passed through from early firmware to the kernel on
boot.
In the UEFI context GUIDs are expected to be rendered in upper case.
The patch uses the formerly unused bit 1 of the parameter str_format
of function uuid_bin_to_str() to indicate if we need upper or lower case
output.
Function uuid_string() in vsprint.c is adjusted to correctly set the bit
depending on the print format code.

uuid_gpt_misc=6d6c9a36-e919-264d-a9ee-bd00379686c7
While the uuids do change on every 'gpt write' command, the values
appear to be taken from the same pool, in the same order.
Assuming U-Boot with RANDOM_UUID=y is deployed on a large number of
devices, all those devices would essentially expose the same UUID,
breaking the assumption of system/RFS/application designers who rely
on UUID as being globally unique (e.g. a database using UUID as key
would alias/mix up entries/records due to duplicated UUID).
The root cause seems to be simply _not_ seeding PRNG before generating
a random value. It turns out this belongs to an established class of
PRNG-specific problems, commonly known as "unseeded randomness", for
which I am able to find below bugs/CVE/CWE:
- https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-0285
("CVE-2015-0285 openssl: handshake with unseeded PRNG")
- https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-9019
("CVE-2015-9019 libxslt: math.random() in xslt uses unseeded
randomness")
- https://cwe.mitre.org/data/definitions/336.html
("CWE-336: Same Seed in Pseudo-Random Number Generator (PRNG)")
The first revision [1] of this patch updated the seed based on the
output of get_timer(), similar to [4].
There are two problems with this approach:
- get_timer() has a poor _ms_ resolution
- when gen_rand_uuid() is called in a loop, get_timer() returns the
same result, leading to the same seed being passed to srand(),
leading to the same uuid being generated for several partitions
with different names
The above drawbacks have been addressed in the second version [2].
In its third revision (current), the patch reworded the description
and summary line to emphasize it is a *fix* rather than an improvement.
Testing [3] consisted of running 'gpt write mmc 1 $partitions' in a
loop on R-Car3 for several minutes, collecting 8844 randomly generated
UUIDS. Two consecutive cold boots are concatenated in the log.
As a result, all uuid values are unique (scripted check).
Thanks to Roman, who reported the issue and provided support in fixing.

The field boot OptionalData in structure _EFI_LOAD_OPTIONS is for binary
data.
When we use `efidebug boot add` we should convert the 5th argument from
UTF-8 to UTF-16 before putting it into the BootXXXX variable.
When printing boot variables with `efidebug boot dump` we should support
the OptionalData being arbitrary binary data. So let's dump the data as
hexadecimal values.
Here is an example session protocol:
=> efidebug boot add 00a1 label1 scsi 0:1 doit1 'my option'
=> efidebug boot add 00a2 label2 scsi 0:1 doit2
=> efidebug boot dump

This function may be called from tracing code, since that code needs to
read the timer and this often requires calling do_div(), which calls
__div64_32(). If this function is instrumented it causes an infinite loop,
since emitting a trace record requests the time, which in turn emits a
trace record, etc.
Update the prototype to prevent instrumentation code being added.
