OVP Peripheral Model: ArmSmartLoaderArmLinux



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 ARM based Linux kernel boot: Loads Linux kernel image file and (optional) initial ram disk image into memory. Writes ATAG data into memory. Writes tiny boot code at physical memory base that configures the registers as expected by Linux Kernel and then jumps to boot address (image load address by default).

Limitations

Only supports little endian

Reference

See ARM Linux boot requirements in Linux source tree at documentation/arm/Booting

Location

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



Peripheral Instance Parameters

This model accepts the following parameters:
