From 29318db133d0b2523bda771f76aa50c08842527f Mon Sep 17 00:00:00 2001 From: Chalapathi V Date: Wed, 26 Jun 2024 04:05:24 -0500 Subject: hw/ssi: Add SPI model MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SPI controller device model supports a connection to a single SPI responder. This provide access to SPI seeproms, TPM, flash device and an ADC controller. All SPI function control is mapped into the SPI register space to enable full control by firmware. In this commit SPI configuration component is modelled which contains all SPI configuration and status registers as well as the hold registers for data to be sent or having been received. An existing QEMU SSI framework is used and SSI_BUS is created.
