mark 83697fa8b9 Added a field sc_ixfer to the sfas_softc structure to allow the standard 
sfas ixfer() routine to be overridden with a card specific one.
 1997-02-11 03:33:46 +00:00
mark faec60a06c Add a define for the cpu_functions structure member cf_sleep. 1997-02-10 04:01:08 +00:00
mark 700a2e2041 Remove the code force the processor into a sleep mode during idle() and 
instead call the sleep function defined in the cpufunctions structure.
 1997-02-10 03:57:42 +00:00
mark 187f8c7c3d Remove local definitions of macros to push and pull trapframes and instead 
include machine/frame.h to get these definitions.
 1997-02-10 03:50:53 +00:00
mark 60cab4af5d Centralise the definition of the ASM macros used to push and pull and 
trapframe and irqframe structures defined here top and from the stack.

mark 28203348d8 Process the parameters passed in the SYNC_ICACHE sysarch() call and just 
sync the caches for the specified virtual address range.
 1997-02-10 03:19:36 +00:00
mark 5f3ba778ab Define parameters for the arm32_sync_icache() function. 1997-02-10 03:14:22 +00:00
mark 51495d4bf1 Updated to work with the recent changes to the MI DDB code. 1997-02-04 07:15:46 +00:00
mark 6ec73b6227 Removed all the CPU_SA110 conditional compilation. All the cache 
cleaning calls will now be indirected throught the cpu_functions
that will have the correct function pointers for the CPU in use.
All register fixup code following aborts has been removed and
instead a call to the cpu_*abt_fixup() routine is called instead
to provide the correct fixed based on the CPU type and abort mode.
 1997-02-04 07:12:30 +00:00
mark 06f80904ec Set the sc_ixfer function pointer to the default sfas_ixfer() function 
during initialisation if the pointer is NULL.
Use the sc_ixfer function pointer in the sfas softc when doing
immediate polled transfers.
 1997-02-04 06:57:47 +00:00
mark 1715a217cf Removed the SA110 condition compilation and instead test the cputype 
variable to determine what adjustment is required for the trace back PC.
 1997-02-04 06:53:41 +00:00
mark 403608bdbb Add defines for the cpu_functions structure members cf_cache_purgeID and 
cf_context_switch.
 1997-02-04 06:51:34 +00:00
mark e626201c12 Adopt as standard, the instruction sequence for storing the trapframe that 
includes the workaround from the SA110 STM^ bug. This allows one piece of
code to be used to store the trapframe on all CPU types.
 1997-02-04 06:49:08 +00:00
mark f6570e9a78 Update for recent changes. Added options to support ARM6, ARM7 and SA110 
CPUs in a single kernel.

mark c2a184bc45 Fix SA110 CPU ID. 1997-02-04 06:30:57 +00:00
mark 64c714c82c This configuration file is dead now that all ARM6/7 & SA110 CPUs are 
supported in the one kernel.
 1997-02-04 06:29:57 +00:00
mark 2f04af3ab0 This file is no longer needed as the functionally it provided is now 
provided within cpufunc_asm.S
 1997-02-04 06:24:27 +00:00
mark c2a2cba5dd Add Makefile as a dependancy cpufunc.o and cpufunc_asm.o 1997-02-04 06:19:08 +00:00
mark 663277e00c Simplify cpu option checks now that multiple CPU types are supported in a 
single kernel.
 1997-02-04 06:10:48 +00:00
mark f53ea9b979 Only include md_hooks.c if md AND memory_disk_hooks are defined. 
Updated for changes in the cpu specific functions (addition of
cpufunc.c and cpufunc_asm.S and removal of coproc15.S).
 1997-02-04 05:58:55 +00:00
mark ee02ce0401 Major overhaul of handling of CPU/MMU/TLB specific functions. This allows 
different ARM CPUS with different cache architectures for example to be
supported in a single kernel.
        - All CPU/MMU/TLB specific functions are now held as function
          pointers in a cpu_functions structure defined in machine/cpufunc.h
	  All coproc 15 accesses, TLB flushing, cache cleaning/flushing
          and abort correction functions are now defined in this structure.
        - cpufuncs is a global structure that is setup during initarm()
          that holds all the function pointers for the booted CPU.
	- A global variable 'cputype' now defines the probed cputype.
        - All the existing functions for manipulating CPU specific features
          have been replaced with macros defined in machine/cpufunc.h
          that will call the appropriate function in the cpu_functions
          structure.
	- CPU functions are provided for selected CPU types (config options)
          and the appropriate cpu_functions structure is chosen during
          booting, based on the probed CPU type.
	- All the required functions for existing CPU types (ARM6, ARM7 and
          SA110) have been implemented.

mark fd6725ae88 Remove all the old do_mountroot() junk that was built into GENERIC kernels. 
This code has been replaced with the more flexible MI setroot() code.

perry 19d153fc48 Nuke some options GENERIC residue. 1997-02-04 04:57:10 +00:00
perry 0b3a46d6b3 Nuke some GENERIC residue. 1997-02-04 04:31:55 +00:00
mark 7ef8e3bcd9 Fix declaration of the interrupt handler to match new prototype for IRQ 
function pointers.
 1997-02-04 02:23:35 +00:00
mark aab5efa574 Updated to use the new bus space interface code. Use a number of bus 
space handles to describe the task file registers, aux register, 16 bit
data register and 32 bit data register.
The wdc softc structure has been moved to a separate file.
Added support for multiple attachments by separating the core of the
probe and attach functions from the mainbus probe and attach routines.
Added a new wdc flags 32_BIT so that the wd can determine 32 bit xfer
support from the wdc device.
 1997-02-04 02:04:51 +00:00
mark 649a90497e No need to check for CPU_ARM7500 being defined as this option implies 
CPU_ARM7 which has to be checked anyway.
