MFaltix: Add support for Pre-Boot Virtual Memory (PBVM) to the loader.
PBVM allows us to link the kernel at a fixed virtual address without having to make any assumptions about the physical memory layout. On the SGI Altix 350 for example, there's no usuable physical memory below 192GB. Also, the PBVM allows us to control better where we're going to physically load the kernel and its modules so that we can make sure we load the kernel in memory that's close to the BSP.
The PBVM is managed by a simple page table. The minimum size of the page table is 4KB (EFI page size) and the maximum is currently set to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment one can specify in a linker script. The bottom line is that PBVM is between 64KB and 8GB in size.
The loader maps the PBVM page table at a fixed virtual address and using a single translations. The PBVM itself is also mapped using a single translation for a maximum of 32MB.
While here, increase the heap in the EFI loader from 512KB to 2MB and set the stage for supporting relocatable modules.

Major rework of the ia64 loaders. The two primary objectives are: 1. Make libefi portable by removing ia64 specific code and build it on i386 and amd64 by default to prevent regressions. These changes include fixes and improvements over previous code to establish or improve APIs where none existed or when the amount of kluging was unacceptably high. 2. Increase the amount of sharing between the efi and ski loaders to improve maintainability of the loaders and simplify making changes to the loader-kernel handshaking in the future.
The version of the efi and ski loaders are now both changed to 1.2 as user visible improvements and changes have been made.

Extend struct devdesc with a unit field, called d_unit. Promote the device (kind) specific unit field to the common field. This change allows a future version of libefi to work without requiring anything more than what is defined in struct devdesc and as such makes it possible to compile said version of libefi for different platforms without requiring that those platforms have identical derivatives of struct devdesc.

Remove special casing for running in the simulator from the kernel and instead add platform, firmware and EFI stubs to the loader. The net effect of this change is that besides a special console and disk driver, the kernel has no knowledge of the simulator. This has the following advantages: o Simulator support is much harder to break, o It's easier to make use of more feature complete simulators. This would only need a change in the simulator specific loader, o Running SMP kernels within the simulator. Note that ski at this time does not simulate IPIs, so there's no way to start APs.
The platform, firmware and EFI stubs describe the following hardware: o 4 CPU Itanium, o 128 MB RAM within the 4GB address space, o 64 MB RAM above the 4GB address space.
NOTE: The stubs in the skiloader describe a machine that should in parts be defined by the simulator. Things like processor interrupt block and AP wakeup vector cannot be choosen at random because they require interpretation by the simulator. Currently the simulator is ignorant of this.
This change introduces an unofficial SSC call SSC_SAL_SET_VECTORS which is ignored by the simulator.
Tested with: ski (version 0.943 for linux)

Add a version of the loader which runs under SKI, the HP ia64 simulator. This loader is quite functional and can load and run kernels. The kernels don't quite work right after loading but that should be easily fixable.
