OVP Peripheral Model: ArmSmartLoaderArm64Linux



Model Specific Information

This page provides introductory usage information for an Imperas OVP peripheral behavioral model. The page is split into sections providing specific information for this peripheral, including any ports for connecting into a platform, registers, other component parts, and configuration options and general information for peripheral modeling with Imperas OVP.

Licensing

Open Source Apache 2.0

Description

Psuedo-peripheral to perform memory initialisation for an Arm64 Linux kernel boot: Loads Linux kernel image file, device tree blob and (optional) initial ram disk image into memory. Writes tiny boot code at physical memory base to configure regs and then jump to the Kernel entry. Modifies the device tree to always use the spin-table enable-method.

Limitations

Only supports little endian

Reference

See ARM Linux boot requirements in Linux source tree at documentation/arm64/booting.txt

Location

The SmartLoaderArm64Linux peripheral model is located in an Imperas/OVP installation at the VLNV: arm.ovpworld.org / peripheral / SmartLoaderArm64Linux / 1.0.
