Description

Ultibo QEMU VersatilePB unit

This unit serves to include all units relevant to the QEMU VersatilePB and to register the drivers that are appropriate to the configuration.

This includes standard interfaces such as network, filesystem and storage as well as drivers that are specific to the VersatilePB and may or may not be included by anything else.

The unit also provides a very simple clock device driver for the 24MHz clock included in the Versatile PB System Control registers. This clock is 32bit only, runs at a fixed rate of 24MHz and cannot be stopped or reset.

Additional units can be included anywhere within a program and they will be linked during the compile process. This unit simply provides a convenient way to ensure all relevant units have been included and the standard drivers registered.

Constants


QEMUVersatilePB specific constants NAME_*
VERSATILEPB_CLOCK_DESCRIPTION = 'VersatilePB 24MHz Clock'; Description of 24MHz clock device


Type definitions

None defined

Public variables

Function declarations


Initialization functions 

procedure QEMUVersatilePBInit;
Description: Initialize the QEMUVersatilePB unit and parameters
Note Called only during system startup


QEMUVersatilePB MMCI functions 

function MMCIGetCardDetect(MMC:PMMCDevice):LongWord;
Description: Implementation of MMCDeviceGetCardDetect API for QEMUVPB MMCI
Note Not intended to be called directly by applications, use MMCDeviceGetCardDetect instead.

Not currently used as the VERSATILEPB_SYS_MCI register is not connected in QEMUVPB 


function MMCIGetWriteProtect(MMC:PMMCDevice):LongWord;
Description: Implementation of MMCDeviceGetWriteProtect API for QEMUVPB MMCI
Note Not intended to be called directly by applications, use MMCDeviceGetWriteProtect instead.

Not currently used as the VERSATILEPB_SYS_MCI register is not connected in QEMUVPB


QEMUVersatilePB clock functions 

function VersatilePBClockRead(Clock:PClockDevice):LongWord;
Description: Implementation of ClockDeviceRead API for the 24MHz Clock
Note Not intended to be called directly by applications, use ClockDeviceRead instead. 


function VersatilePBClockRead64(Clock:PClockDevice):Int64;
Description: Implementation of ClockDeviceRead64 API for the 24MHz Clock
Note Not intended to be called directly by applications, use ClockDeviceRead64 instead.
