Remove the definition of CURRENT_PAGEDIR_HOLE and CURRENT_PAGEDIR_BASE

More reworking in initarm().
...
Further cleanup and simply the allocation and mapping of the kernel
pagetables and static data pages.
Removed the page directory page table as it is no longer necessary.
Changed the allocation of the proc0 L1 page table and L2 page table
that maps the page tables to map these pages into kernel virtual
address space.
Updated for pv_addr_t argument changes to pmap_bootstrap().
1998-08-28 02:58:41 +00:00
133f5c93f0
Updated for pmap_bootstrap() argument change. Modify ofw_configmem()
...
to obtains pv_addr_t structures for the proc0 L1 page table and the proc0
pagetable that maps page tables.
Use the virtual address from the pv_addr_t structure for the proc0 L1 page
table when calling pmap_bootstrap rather than relying on a special mapping
at PAGE_DIRS_BASE.
Modify ofw_construct_proc0_addrspace() for similar changes to
ofw_configmem().
Remove the kernel_pde page table in ofw_construct_proc0_addrspace() as it
it now longer needed.

Modify the arguments to pmap_bootstrap() to take a pv_addr_t structure

Simplified serveral parts of the initarm() to make the code clearer and

b75234f009
Add calls to cpu_cache_cleanID() after calling setttb() during initarm().

This is necessary as the memory addresses being used for the cache clean
(if the CPU is a SA110) may have been remapped by the setttb() call and
thus the cache could loose sync with memory.
