Re: [U-Boot] [PATCH] lib: uuid: Improve randomness of uuid values on RANDOM_UUID=y

Hi Lukasz, Thanks to Roman, we found a potential regression in this solution. Particularly when gen_rand_uuid() is called in a loop, get_timer(0) might return the same value, leading to the same seed value being passed to srand(), leading to the same uuid value being generated for several

[U-Boot] [PATCH] lib: uuid: Improve randomness of uuid values on RANDOM_UUID=y

The random uuid values (enabled via CONFIG_RANDOM_UUID=y) on our platform are always the same. Below is consistent on each cold boot: => ### reach U-Boot prompt => setenv uuid_gpt_misc => gpt verify mmc 1 $partitions Verify GPT: success! => print uuid_gpt_misc
