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.
[SMBIOS] Interpret UUIDs as being in network-endian order
Various specification documents disagree about the byte ordering of
UUIDs. However, SMBIOS seems to use the standard in which everything is
in network-endian order.
This doesn't affect anything sent on the wire; only what gets printed on
the screen when the "uuid" variable is displayed.
[Settings] Remove assumption that all settings have DHCP tag values
Allow for settings to be described by something other than a DHCP option
tag if desirable. Currently used only for the MAC address setting.
Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c.
Remove notion of settings from dhcppkt.c.
Rationalise dhcp.c to use settings API only for final registration of the
DHCP options, rather than using {store,fetch}_setting throughout.
Add the notion of the settings hierarchy, complete with
register/unregister routines.
Rename set->store and get->fetch to avoid naming conflicts with get/put
as used in reference counting.
[Settings] Start revamping the configuration settings API.
Add the concept of an abstract configuration setting, comprising a (DHCP)
tag value and an associated byte sequence.
Add the concept of a settings namespace.
Add functions for extracting string, IPv4 address, and signed and
unsigned integer values from configuration settings (analogous to
dhcp_snprintf(), dhcp_ipv4_option(), etc.).
Update functions for parsing and formatting named/typed options to work
with new settings API.
Update NVO commands and config UI to use new settings API.
Timers are sometimes required before the call to initialise(), so we
cannot rely on initialise() to set up the timers before use.
Also fix a potential integer overflow issue in generic_currticks_udelay()
Add missing comments to timer code.
Lock system if no suitable timer source is found.
Fix initialisation order so that timers are initialised before code that
needs to use them.
[Settings] Allow encapsulated options to be specified as named settings
Allow encapsulated options to be specified as e.g. "175.3". As a
side-effect, change the separator character for the type field from "." to
":"; for example, the IP address pseudo-option is now "175.3:ipv4".
[Settings] Add int16, int32 and hex-string configuration setting types
Add parse and display routines for 16-bit and 32-bit integer configuration
settings.
Add parse and display routines for hex-string configuration settings.
Assume hex-string as a configuration setting type if no type is explicitly
specified.
show_setting() and related functions now return an "actual length" in the
style of snprintf(). This is to allow consumers to allocate buffers large
enough to hold the formatted setting.
Replace a printf with a DBG in timer_rtdsc.c
Replace a printf in timer.c with assert
Return proper error codes from timer drivers

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.
