[PATCH] imx8m: ddr_init: Move ddr_init() messages to debug level
by Fabio Estevam 28 Dec '19

28 Dec '19

Currently inside ddr_init() there is a mix of printf() and debug() level messages. Since this type of information is useful for debug purposes, convert all of them to debug level for consistency.

Hi Simon, Been a couple of weeks. I have obtained a SuzyQable and its working well with bob. I can see RxTx from Cr50, AP and EC. On mainline linux from ArchLinuxArm I can see earlyprintk as well.

[PATCH 0/7] Add a random number generator uclass
by Sughosh Ganu 28 Dec '19

28 Dec '19

Add a random number generator(rng) uclass to facilitate adding drivers for rng devices. I plan to add an implementation of the EFI_RNG_PROTOCOL, which would get the random number from the rng uclass -- the protocol would be used by the efi stub for getting a random number for the kaslr feature. The patch series also adds a driver for the rng device found on the stm32mp1 platforms. A dummy rng driver for sandbox has also been added, along with the unit test for the rng uclass.
