These alternative macros have a workaround for the STM^ bug in revision < 3
StrongARM CPU's that causes incorrect register saving if a cache line fill
is in progress during the STM.
a podulebus.
Make sure the podulebus driver conforms to the Acorn expansion card
specification:
- Probe the podule bus using sync access cycles rather than slow access
cycles.
- Read the podulebus header/ROM using sync access cycles rather than slow
access cycles
Added support the new instructions defined in the ARM V4 Architecture
Reference manual (long multiplies, half word load and stores,
half word/byte signed loads).
Added support for the ARM810 IMB architecture defined SWIs.
Fixed bug in calculating some immediate constants.
Added support for the wfs, rfs, wfc, rfc instructions
Added support for the floating point compare instructions
Added ldf, stf, ldc and stc instructions.
Fixed mis-disassembly of some msr/mrs instructions.
The ldm and stm instructions will modify the direction identifier to
use the stack variations if the base register is r13.
code as video memory must be reserved from main memory for the display.
In addition this adds generic support for using DRAM for video memory
on all machines. All video memory accessing should use the video_memory_t
structure.
Added support for the RC7500 motherboard. The RC7500 support includes a
replacement init_arm() function. This also supports the RC7500 prom debug
monitor for debugging the kernel boot.
dumps now work so call dumpsys() following a panic.
Added support for the SA110. This mainly consists of making sure the data
cache is cleaned when appropriate and that the instruction cache is
kept in sync during the bootstrap and when signal handlers are built on
the stack.
Use a larger UND32 mode stack if we are configured for KGDB.
Remove KERNEL_PT_KSTACK references as these should have died with the
removal of double mapped kstacks eons ago.
Make sure we call doshutdownhooks() if boot is called while we are still
cold.
Cleaned up prototypes declarations.
Sorted out comment indentation.
clean and tlb flush code along with write buffer drains that are
dependant on the definition of CPU_SA110.
The memory reserved for the L1 pagetables is now wired into the memory map
during the pmap_init rather than at L1 pagetable allocation time.
The L1 pages tables are zeroed during initialisation and when they are
released rather than when they are allocated.
When searching for a free L1 page table start search at the page table
after the last one allocated rather than always starting from the first one.
Added some extra DIAGNOSTIC checks for invalidate page index numbers.
Removed some old debugging code that escaped the last clean up.
Idented comments in line with code.
The irq delivery code has been rewritten. On entry to the irq vector the
processor is switched to SVC32 mode so all interrupt routines now run
in SVC32 mode rather than IRQ32 mode. This fixes lots of irq re-enabling
problems.
Interrupt latency times are now vastly improved for high priority interrupts.
Cleaned up calling ast() before returning to USR32 mode (don't need to
mess about with trapframe copying.
Cleaned up all the comments and sorted out their indentation.
Rewritten the soft interrupt delivery code.
Added generic ARM7500 support rather than just RC7500 support.
