Subject[PATCH 0/3] Add support for Graviton TRNG
Date
AWS Graviton based systems provide an Arm SMC call in the vendor defined
hypervisor region to read random numbers from a HW TRNG and return them to the
guest.

We've observed slower guest boot and especially reboot times due to lack of
entropy and providing access to a TRNG is meant to address this.

Ali Saidi (3):
arm/arm64: Add smccc hypervisor service identifiers
arm64: export acpi_psci_use_hvc
hwrng: Add support for AWS Graviton TRNG
