Cut out almost all the optional code paths, drastically simplifying the
...
flow of control through this code.
We now always add PCI and PnP headers even for ISA ROMs; there's no harm
in doing so.
UNDI loader is still missing.

init_librm() and prot_call() are now real-mode far calls.
...
install() now calls relocate(), moves the protected-mode code to the new
location, and calls hide_etherboot().

Restructured PCI subsystem to fit the new device model.
...
Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.
Split rarely-used PCI functions out into pciextra.c.
Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.
Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).

Add infrastructure to support access to .data16 (and .text16) variables
...
from protected-mode code.
Set up %ds to point to .data16 in prot_to_real, so that code specified
via REAL_EXEC() and friends can access variables in .data16.
Move most real-mode librm variables from .text16 to .data16.

BSS is now zeroed by libprefix (along with the otherwise non-zeroable
...
portions such as the stack) during the installation process.
init_fns() are called from main(). We need to think about initial
control flow some more.

This should be much more elegant: we use flat real mode for the

highmem data, so decompress16 will be able to unpack blocks bigger
than 64kB.

running the decompresser in 16:16 protected mode using the real-mode
stack. However, there's an even simpler way to do it...

Header rearrangement.
...
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/. Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.
