Include config/local/$file in config/$file where it makes sense and
create empty local configs during build if not present.

The NMB protocol code came from legacy Etherboot and was never updated
to work as a gPXE protocol. There has been no demand for this protocol,
so this patch removes it.

I have an unfinished NFSv3 over TCP implementation for gPXE that can be
used as the base for new work, should we want to resurrect this
protocol.

For extremely tight space requirements and specific applications, it is
sometimes desirable to create gPXE images that cannot provide the PXE API
functionality to client programs. Add a configuration header option,
PXE_STACK, that can be removed to remove this stack. Also add PXE_MENU
to control the PXE boot menu, which most uses of gPXE do not need.

Wireless gPXE images are already so large that user-friendliness
seems to trump ROM-size friendliness in this case.

WEP is a highly flawed cryptosystem, barely better than no encryption at all,
but many people still use it. It does have the advantage of being very simple
and small in code size.

[iwmgmt] Add wireless management commands and text for common errors
Add commands `iwstat' (to list 802.11-specific status information for
802.11 devices) and `iwlist' (to scan for available networks and print
a list along with security information).

SRP is the SCSI RDMA Protocol. It allows for a method of SAN booting
whereby the target is responsible for reading and writing data using
Remote DMA directly to the initiator's memory. The software initiator
merely sends and receives SCSI commands; it never has to touch the
actual data.
These commands can be used to activate or deactivate the PXE API (on a
specifiable network interface).
This is currently of limited use, since most image formats will call
shutdown() before booting the image, meaning that the underlying net
device gets shut down during remove_devices() anyway.
[romprefix] Add vendor branding facilities and guidelines
Some hardware vendors have been known to remove all gPXE-related
branding from ROMs that they build. While this is not prohibited by
the GPL, it is a little impolite.
Add a facility for adding branding messages via two #defines
(PRODUCT_NAME and PRODUCT_SHORT_NAME) in config/general.h. This
should accommodate all known OEM-mandated branding requirements.
Vendors with branding requirements that cannot be satisfied by using
PRODUCT_NAME and/or PRODUCT_SHORT_NAME should contact us so that we
can extended this facility as necessary.
[efi] Add EFI image format and basic runtime environment
We have EFI APIs for CPU I/O, PCI I/O, timers, console I/O, user
access and user memory allocation.
EFI executables are created using the vanilla GNU toolchain, with the
EXE header handcrafted in assembly and relocations generated by a
custom efilink utility.
This change allows the time for which shell banners are displayed to
be configured in the config.h file. The ability to access the shell
can also be effectively disabled by setting this timeout to zero.
This commit implements GDB over UDP. Using UDP is more complex than
serial and has required some restructuring.
The GDB stub is now built using one or both of GDBSERIAL and GDBUDP
config.h options.
To enter the debugger, execute the gPXE shell command:
gdbstub <transport> [<options>...]
Where <transport> is "serial" or "udp". For "udp", the name of a
configured network device is required:
gdbstub udp net0
The GDB stub listens on UDP port 43770 by default.
[ELF] Add ability to boot ELF images generated by wraplinux and mkelfImage
Delete ELF as a generic image type. The method for invoking an
ELF-based image (as well as any tables that must be set up to allow it
to boot) will always depend on the specific architecture. core/elf.c
now only provides the elf_load() function, to avoid duplicating
functionality between ELF-based image types.
Add arch/i386/image/elfboot.c, to handle the generic case of 32-bit
x86 ELF images. We don't currently set up any multiboot tables, ELF
notes, etc. This seems to be sufficient for loading kernels generated
using both wraplinux and coreboot's mkelfImage.
Note that while Etherboot 5.4 allowed ELF images to return, we don't.
There is no callback mechanism for the loaded image to shut down gPXE,
which means that we have to shut down before invoking the image. This
means that we lose device state, protection against being trampled on,
etc. It is not safe to continue afterwards.
During development it is often handy to change the config.h options from
their defaults, for example to enable debugging features.
To prevent accidental commits of debugging config.h changes, mdc
suggested having a config-local.h that is excluded from source control.
This file acts as a temporary config.h and can override any of the
defaults.
This commit is an attempt to implement the config-local.h feature.
The config.h file now has the following as its last line:
/* @TRYSOURCE config-local.h */
The @TRYSOURCE directive causes config-local.h to be included at that
point in the file. If config-local.h does not exist, no error will be
printed and parsing will continue as normal. Therefore, mkconfig.pl is
"trying" to "source" config-local.h.
The GDBSYM config.h option was an attempt at QEMU GDB debugging. I have
removed the code since it is unused and may confuse people wanting to
use the GDB stub.
Timer subsystem initialization code in core/timer.c
Split the BIOS and RTDSC timer drivers from i386_timer.c
Split arch/i386/firmware/pcbios/bios.c into the RTSDC
timer driver and arch/i386/core/nap.c
Split the headers properly:
include/unistd.h - delay functions to be used by the
gPXE core and drivers.
include/gpxe/timer.h - the fimer subsystem interface
to be used by the timer drivers
and currticks() to be used by
the code gPXE subsystems.
include/latch.h - removed
include/timer.h - scheduled for removal. Some driver
are using currticks, which is
only for core subsystems.
