The bulk of these changes are an effort to unify Tegra186 builds with

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.

The random uuid values (enabled via CONFIG_RANDOM_UUID=y) on our
platform are always the same. Below is consistent on each cold boot:
=> ### interrupt autoboot
=> env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
...
uuid_gpt_misc=d117f98e-6f2c-d04b-a5b2-331a19f91cb2
=> env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
...
uuid_gpt_misc=ad5ec4b6-2d9f-8544-9417-fe3bd1c9b1b3
=> env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
...

...
uuid_gpt_misc=d4981a2b-0478-544e-9607-7fd3c651068d
=> env default -a; gpt write mmc 1 $partitions; print uuid_gpt_misc
...
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.

When phys_addr_t printf specifier support was first introduced in commit
1eebd14b79 ("vsprintf: Add modifier for phys_addr_t"), it was enabled
only if CONFIG_CMD_NET was selected. Since physical addresses are not
unique to networking support it doesn't make sense to conditionally add
it in those cases only. Move support for it outside of the CMD_NET guard
so that the specifier is always supported.
