From 8ef38186faea3d9b5e6f0f1242f668cb7e7a3d52 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Mon, 12 Jun 2000 19:57:02 +0000 Subject: Patch from John Cotton , Charles-Antoine Gauthier , and Darlene A. Stewart to add support for a number of very significant things: + BSPs for many variations on the Motorola MBX8xx board series + Cache Manager including initial support for m68040 and PowerPC + Rework of mpc8xx libcpu code so all mpc8xx CPUs now use same code base. + Rework of eth_comm BSP to utiltize above. John reports this works on the 821 and 860 --- c/src/lib/libcpu/powerpc/shared/cpu.h | 27 ++++++++++++--------------- 1 file changed, 12 insertions(+), 15 deletions(-) (limited to 'c/src/lib/libcpu/powerpc/shared/cpu.h') diff --git a/c/src/lib/libcpu/powerpc/shared/cpu.h b/c/src/lib/libcpu/powerpc/shared/cpu.h index 3fe27f5496..374ea6c54c 100644 --- a/c/src/lib/libcpu/powerpc/shared/cpu.h +++ b/c/src/lib/libcpu/powerpc/shared/cpu.h @@ -1,7 +1,7 @@ /* * cpu.h * - * This file contains some powerpc MSR and registers access definitions. + * This file contains some powerpc MSR and registers access definitions. * * It is a stripped down version of linux ppc processor.h file... * @@ -15,10 +15,12 @@ * $Id$ */ -#ifndef __ASM_PPC_PROCESSOR_H -#define __ASM_PPC_PROCESSOR_H +#ifndef __PPC_CPU_H +#define __PPC_CPU_H -#include +#ifdef __cplusplus +extern "C" { +#endif /* Bit encodings for Machine State Register (MSR) */ #define MSR_POW (1<<18) /* Enable Power Management */ @@ -247,16 +249,6 @@ static inline void PPC_Set_timebase_register (unsigned long long tbr) } -#define _CPU_Data_Cache_Block_Flush( _address ) \ - do { register void *__address = (_address); \ - register unsigned32 _zero = 0; \ - asm volatile ( "dcbf %0,%1" : \ - "=r" (_zero), "=r" (__address) : \ - "0" (_zero), "1" (__address) \ - ); \ - } while (0) - - /* * Enable interrupts to the previous level (returned by _CPU_ISR_Disable). * This indicates the end of an RTEMS critical section.
