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 EPIC unit. - -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 - 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 external - interrupts. - - The routine epic_exception shall be called by - exception vector at location 0x500, i.e., - 603e core external exception vector. - -2. The host system is responsible for configuring - the MPC8240 including Embedded Utilities Memory - Block. All EPIC driver functions require the - content of Embedded Utilities Memory Block - Base Address Register, EUMBBAR, as the first - parameter. - -3. Before EPIC unit of MPC8240 can be used, - initialize EPIC unit by calling epicInit - with the corresponding parameters. - - The initialization shall disable the 603e - core External Exception by calling CoreExtIntDisable( ). - Next, call epicInit( ). Last, enable the 603e core - External Exception by calling CoreExtIntEnable( ). - -4. After EPIC unit has been successfully initialized, - epicIntSourceSet( ) shall be used to register each - external interrupt source. Anytime, an external - interrupt source can be disabled or enabled by - calling corresponding function, epicIntDisable( ), - or epicIntEnable( ). - - Global Timers' resource, base count and frequency, - can be changed by calling epicTmFrequencySet( ) - and epicTmBaseSet( ). - - To stop counting a specific global timer, use - the function, epicTmInhibit while epicTmEnable - can be used to start counting a timer. - -5. To mask a set of external interrupts that are - are certain level below, epicIntPrioritySet( ) - can be used. For example, if the processor's - current task priority register is set to 0x7, - only interrupts of priority 0x8 or higher will - be passed to the processor. - - Be careful when using this function. It may - corrupt the current interrupt pending, selector, - and request registers, resulting an invalid vetor. - - After enabling an interrupt, disable it may also - cause an invalid vector. User may consider using - the spurious vector interrupt service routine to - handle this case. - -6. The EPIC driver routines contains a set - of utilities, Set and Get, for host system - to query and modify the desired EPIC source - registers. - -7. Each external interrupt source shall register - its interrupt service routine. The routine - shall contain all interrupt source specific - processes and keep as short as possible. - - Special customized end of interrupt routine - is optional. If it is needed, it shall contain - the external interrupt source specific end of - interrupt process. - - External interrupt exception vector at 0x500 - shall always call the epicEOI just before - rfi instruction. Refer to the routine, - epic_exception, for a code sample. diff --git a/arch/powerpc/cpu/mpc824x/drivers/epic/epic.h b/arch/powerpc/cpu/mpc824x/drivers/epic/epic.h deleted file mode 100644 index 58f81c5dfd..0000000000 --- a/arch/powerpc/cpu/mpc824x/drivers/epic/epic.h +++ /dev/null @@ -1,163 +0,0 @@ -/********************************************************************* - * mpc8240epic.h - EPIC module of the MPC8240 micro-controller - * - * Copyrigh 1999 Motorola Inc. - * - * Modification History: - * ===================== - * 01a,04Feb99,My Created. - * 15Nov200, robt -modified to use in U-Boot - * -*/ - -#ifndef __INCEPICh -#define __INCEPICh - -#define ULONG unsigned long -#define MAXVEC 20 -#define MAXIRQ 5 /* IRQs */ -#define EPIC_DIRECT_IRQ 0 /* Direct interrupt type */ - -/* EPIC register addresses */ - -#define EPIC_EUMBBAR 0x40000 /* EUMBBAR of EPIC */ -#define EPIC_FEATURES_REG (EPIC_EUMBBAR + 0x01000)/* Feature reporting */ -#define EPIC_GLOBAL_REG (EPIC_EUMBBAR + 0x01020)/* Global config. */ -#define EPIC_INT_CONF_REG (EPIC_EUMBBAR + 0x01030)/* Interrupt config. */ -#define EPIC_VENDOR_ID_REG (EPIC_EUMBBAR + 0x01080)/* Vendor id */ -#define EPIC_PROC_INIT_REG (EPIC_EUMBBAR + 0x01090)/* Processor init. */ -#define EPIC_SPUR_VEC_REG (EPIC_EUMBBAR + 0x010e0)/* Spurious vector */ -#define EPIC_TM_FREQ_REG (EPIC_EUMBBAR + 0x010f0)/* Timer Frequency */ - -#define EPIC_TM0_CUR_COUNT_REG (EPIC_EUMBBAR + 0x01100)/* Gbl TM0 Cur.
