Check the real-mode? OF property to find out whether we operate in real or virtual mode. In virtual mode we have to do memory mapping. On PowerMacs it is usually false while on pSeries we have found that it is true. The real-mode? property is not available on sparc64.

In the case of non-sequential mappings, ofw_mapmem() could ask Open Firmware to map a memory region with negative length, causing crashes and Undefined Behavior. Add the appropriate check to make the behavior defined.

Make code match comment: make the smallest unit of page allocation from OpenFirmware be 16 pages to avoid fragmentation in the list of mappings returned when the kernel requests it in pmap_bootstrap.
This allows a static buffer to be used when obtaining the existing mappings - very useful on the G5 when random physical pages can't be grabbed because they can't be BAT-mapped.

Change ofw_readin/ofw_copyin to map the entire region before copying, rather than a page at a time. This was creating far too many single-page mappings, and eventually OFW overflowed some internal data structure and refused to map any more. The new algorithm creates far less mappings and fixed a bug where multiple mappings for the same page would be created.
'Twas known this was a problem, but only became urgent when the install CD's mfs_root grew large enough to cause the overflow.

Correctly calculate size of memory to be mapped when copying. Removal of the 256Mb 1:1 BAT mapping exposed this as copying into memory that hadn't been claimed from OpenFirmware.

Only print out an error if returned data size is < 0. A value of 0 happens almost every time at the end of a file when using NFS.

Major rework of how we copy data into kernel space.
We now talk to the memory and mmu instances directly rather than using the OpenFirmware "claim" method.

Mega-patch for OpenFirmware loader support.
- Flesh out ofw_readin routine. - Add OpenFirmware load and exec routines. - Make sure memory allocation for the kernel is done correctly. - Change the way the heap is allocated so as to make it easier to deallocate when we hand over. - Add a command to print memory maps similar to the one for ia64.
With this patch, I can now load and hand over to a kernel on my iMac. There are some problems with OpenFirmware routines failing after the hand over that still need to be addressed.

Bootstrap updates.
- Move some startup code from MD to MI sections - Add a 'copyout' and some copyout-related functions. These will be obsoleted when BTX is available for the 386 and the kernel load area becomes directly addressable. - Add the ability load an arbitrary file as a module, associating and arbitrary type string with it. This can be used eg. for loading splash-screen images etc. - Add KLD module dependancy infrastructure. We know how to look for dependancies inside KLD modules, how to resolve these dependancies and what to do if things go wrong. Only works for a.out at the moment, due to lack of an MI ELF loader. Attach KLD module information to loaded modules as metadata, but don't pass it to the kernel (it can find it itself). - Load a.out KLD modules on a page boundary. Only pad the a.out BSS for the kernel, as it may want to throw symbols away. (We might want to do this for KLD modules too.) - Allow commands to be hidden from the '?' display, to avoid cluttering it with things like 'echo'. Add 'echo'. - Bring the 'prompt' command into line with the parser syntax. - Fix the verbose 'ls'; it was using an uninitialised stack variable. - Add a '-v' flag to 'lsmod' to have it display module metadata as well (not terribly useful for the average user) - Support a 'module searchpath' for required modules. - The bootstrap file on i386 is now called 'loader' to permit the /boot directory to use that name. - Discard the old i386 pread() function, as it's replaced by arch_readin()

Bootloader update.
- Implement a new copyin/readin interface for loading modules. This allows the module loaders to become MI, reducing code duplication. - Simplify the search for an image activator for the loaded kernel. - Use the common module management code for all module metadata. - Add an 'unload' command that throws everything away. - Move the a.out module loader to MI code, add support for a.out kld modules.
