The driver routines are not -written for any specific operating system. -They serves the purpose of code sample, and -jump-start for using the MPC8240 DMA controller. - -For the reason of correctness of C language -syntax, these files are compiled by Metaware -C compiler and assembler. - -ENDIAN NOTATION: - -The algorithm is designed for big-endian mode, -software is responsible for byte swapping. - -USAGE: - -1. The host system that is running on MPC8240 - or using MPC8240 as I/O device shall link - the files listed here. The memory location - of driver routines shall take into account of - that driver routines need to run in supervisor - mode and they process DMA controller interrupt. - -2. The host system is responsible for configuring - the MPC8240 including Embedded Utilities Memory - Block. Since the DMA controller on MPC8240 can - be accessed by either local 603e core or the host - that MPC8240 serves as I/O processor through host - PCI configuration, it is important that the local - processor uses EUMBBAR to access its local DMA - controller while the PCI master uses I/O - processor's PCSRBAR to access the DMA controller - on I/O device. - - To qualify whether is EUMBBAR or PCSRBAR, one - additional parameter is requied from the host - system, LOCAL or REMOTE so that the base value - can be correctly interpreted. - -3. If the host system is also using the EPIC unit - on MPC8240, the system can register the - DMA_ISR with the EPIC including other - desired resources. - - If the host system does not using the EPIC unit - on MPC8240, DMA_ISR function can be called for - each desired time interval. - - In both cases, the host system is free to - provide its own interrupt service routine. - -4. To start a direct mode DMA transaction, - use DMA_Bld_Curr with the start parameter - set to 1. - - To start a chaining mode DMA transaction, - the application shall build descriptors - in memory first, next, use DMA_Bld_Desp - with the start parameter set to 1. - -5. DMA_Start function clears, then sets the CS - bit of DMA mode register. - - DMA_Halt function clears the CS bit of DMA - mode register. - - These functions can be used to start and - halt the DMA transaction. - - If the chaining descriptors has been - modified since the last time a DMA - transaction started, use DMA_Chn_Cnt - function to let DMA controller process - the modified descriptor chain without - stopping or disturbing the current DMA - transaction. - - It is the host system's responsibility of - setting up the correct DMA transfer mode - and pass the correct memory address parameters. - -6. It is the host system's responsibility of - queueing the DMA I/O request. The host - system can call the DMA_ISR with its own - desired interrupt service subroutines to - handle each individual interrupt and queued - DMA I/O requests. - -7. The DMA driver routines contains a set - of utilities, Set and Get, for host system - to query and modify the desired DMA registers. diff --git a/cpu/mpc824x/drivers/dma/dma.h b/cpu/mpc824x/drivers/dma/dma.h deleted file mode 100644 index a21be74ad1..0000000000 --- a/cpu/mpc824x/drivers/dma/dma.h +++ /dev/null @@ -1,326 +0,0 @@ -#ifndef DMA_H -#define DMA_H -/******************************************************* - * - * copyright @ Motorola 1999 - * - *******************************************************/ -#define NUM_DMA_REG 7 -#define DMA_MR_REG 0 -#define DMA_SR_REG 1 -#define DMA_CDAR_REG 2 -#define DMA_SAR_REG 3 -#define DMA_DAR_REG 4 -#define DMA_BCR_REG 5 -#define DMA_NDAR_REG 6 - -typedef enum _dmastatus -{ - DMASUCCESS = 0x1000, - DMALMERROR, - DMAPERROR, - DMACHNBUSY, - DMAEOSINT, - DMAEOCAINT, - DMAINVALID, - DMANOEVENT, -} DMAStatus; - -typedef enum _location -{ - LOCAL = 0, /* local processor accesses on board DMA, - local processor's eumbbar is required */ - REMOTE = 1, /* PCI master accesses DMA on I/O board, - I/O processor's pcsrbar is required */ -} LOCATION; - -typedef enum dma_mr_bit -{ - IRQS = 0x00080000, - PDE = 0x00040000, - DAHTS = 0x00030000, - SAHTS = 0x0000c000, - DAHE = 0x00002000, - SAHE = 0x00001000, - PRC = 0x00000c00, - EIE = 0x00000080, - EOTIE = 0x00000040, - DL = 0x00000008, - CTM = 0x00000004, - CC = 0x00000002, - CS = 0x00000001, -} DMA_MR_BIT; - -typedef enum dma_sr_bit -{ - LME = 0x00000080, - PE = 0x00000010, - CB = 0x00000004, - EOSI = 0x00000002, - EOCAI = 0x00000001, -} DMA_SR_BIT; - -/* structure for DMA Mode Register */ -typedef struct _dma_mr -{ - unsigned int reserved0 : 12; - unsigned int irqs : 1; - unsigned int pde : 1; - unsigned int dahts : 2; - unsigned int sahts : 2; - unsigned int dahe : 1; - unsigned int sahe : 1; - unsigned int prc : 2; - unsigned int reserved1 : 1; - unsigned int eie : 1; - unsigned int eotie : 1; - unsigned int reserved2 : 3; - unsigned int dl : 1; - unsigned int ctm : 1; - /* if chaining mode is enabled, any time, user can modify the - * descriptor and does not need to halt the current DMA transaction. - * Set CC bit, enable DMA to process the modified descriptors - * Hardware will clear this bit each time, DMA starts. - */ - unsigned int cc : 1; - /* cs bit has dua role, halt the current DMA transaction and - * (re)start DMA transaction.
