Embedded Open Modular Architecture/EOMA68/EEPROM Data Format
< Embedded Open Modular Architecture | EOMA68(Redirected from Embedded Open Modular Architecture/EOMA-68/EEPROM Data Format)
assuming agreement on the DIDS layout, below is a proposed definition for the two pages we currently know we must have:
- a device ID page
- a device tree page
To standardize the process of identifying a chassis (or any hardware device, for that matter?) and the components/devices on the chassis which can not be discovered reliably through probing.
Define two DIDS conforming pages, one for identification information and the other for device tree information, and assign them Page Identifiers (PID).
- Name: Device Identification
- PID: 0x01
Page data layout
==== ================2 Device type (assigned centrally) 2 Device revision 4 Vendor ID (assigned centrally) 4 Product ID (vendor generated, registered centrally) N Manufacturer cstring N Product cstring N Serial number cstring* Name: Device tree * PID: 0x02 Page data consists of a standard “dtb” blob as generated by a device tree compiler (dtc) compliant with the Device Tree standard defined at http://devicetree.org
