2006-01-27 Alex Williamson <alex.williamson@hp.com>
	* Found a couple more places where vmcode isn't zeroed, causing the
	  option to get carried over to labels it shouldn't.
2006-01-09 Brett Johnson <brett@hp.com>
	* Released 3.6
2005-12-22 Alex Williamson <alex.williamson@hp.com>
	* Fixed vmcode_name initialization in textmenu chooser
2005-12-01 Alex Williamson <alex.williamson@hp.com>
	* Applied patch from Fred Yang <fred.yang@intel.com> to support the
	  vmm= boot option.  This option specifies the kernel image for a
	  virtual machine monitor (aka hypervisor).  The vmm= and image=
	  options are used together to load both the hypervisor kernel and
	  the guest domain kernel into memory.  If a vmm= option is not
	  specified, elilo defaults to the old behavior of loading and booting
	  to the image= kernel.
	* Added support for compressed image= files when used with the vmm=
	  option.  If the image= file is detected to be gzip compressed, the
	  image will be uncompressed into memory before it is provided to the
	  hypervisor.  Any combination of compressed and uncompressed images
	  can be used for the image and vmm options.
2005-09-15 Brett Johnson <brett@hp.com>
	* Applied patch from Tristan Gingold to add dcache flush and sync with
	  icache to gzip and plain loaders.  This ommision was just noticed now
	  due to the much larger caches in Montecito, and the smaller size of
	  Xen (as compared to the linux kernel).
2004-09-27 Brett Johnson <brett@hp.com>
	* Increase the hardcoded size of the texmenu chooser menu from 16 to 64
2004-09-23 Brett Johnson <brett@hp.com>
	* Fix for 924147.  Thanks to Stephanie Schaaf <sas@sgi.com> for a patch
	  that the fix is based on.
2004-02-19 Brett Johnson <brett@hp.com>
	* Fixed bug where default image initrd would carry over to another
	  image that was selected interactively (iff the newly selected image
	  did not have an initrd).
	* Added support for subnet-specific config files in netfs.
2004-02-17 Brett Johnson <brett@hp.com>
	* integrated ia32 compressed kernel support from Matt Tolentino
	  <matthew.e.tolentino@intel.com>

	  it needs to check if config file path is absolute
	  when printing filename.
	* move definitions of CHAR_SLASH CHAR_BACKSLASH to elilo.h
	* fix a bug in read_config() where it would try other
	  filename even when the user explicitely specified one
	  via -C, now it fails it that file cannot be opened.
	* updated simple chooser set of builtin command keys
	* command keys are only valid if first on the line
	* increase default buffer size and increment when netbooting
2003-06-04 Stephane Eranian <eranian@hpl.hp.com>

	  when using BOOTP (DHCP) only. The prefix is then used for all files
	  open via netfs. Suggestion and initial patch by Guy Laborde from HP.
2003-01-28 Stephane Eranian <eranian@hpl.hp.com>
	* fix the set_default_path() routine in glue_localfs.c. It would not
	  correctly get the basename of the devpath. This caused the
	  elilo.conf not to be found sometimes.
2003-01-21 Stephane Eranian <eranian@hpl.hp.com>
	* fix bug in glue_netfs.c convert_ip2decstr() which caused some IP

2002-09-12 Stephane Eranian <eranian@hpl.hp.com>
	* removed extra free() from fs/ext2fs.c:ext2fs_init_state().
	  Bug report and fix by NOMURA Jun'ichi <j-nomura@ce.jp.nec.com>
	* rewrote fs/ext2fs.c:read_bytes() to large memory stack buffer which
	  was bigger than the 128KB limit of EFI causing some weird fimrware
	  errors. bug reported by OMURA Jun'ichi <j-nomura@ce.jp.nec.com>
	* on IA-64 forbid the use of f32-f127 by the compiler (EFI spec)

	* Changed the despecialization character for the variables from \\ to &
	  to avoid conflicts with \\ as a path separator
2002-06-11 Stephane Eranian <eranian@hpl.hp.com>
	* fixed the return value in efi_main(). elilo was always returning
	  success even in case of failure. Bug reported by Egan Ford <egan@sense.net>
	* applied patch from Richard Hirst <rhirst@linuxcare.com> to fix an
	  initialization bug in choosers/textmenu.c 
	* applied patch from Richard Hirst <rhirst@linuxcare.com> to make elilo
	  compliant with EFI spec with regards to where it looks for files.

	  Brent Casavant <bcasavan@sgi.com>.
	* added slash/backslash conversion for filenames on vfat filesystems.

2001-07-23  Stephane Eranian <eranian@hpl.hp.com>
	* fixed error in netfs.c where the kernel name was not correctly set in
	  netfs_query_layer()
	* fixed to wait_timeout() to correct the problem with the interactive prompt when
	  return is hit directly when no text
	* fixed command line argument destruction problem, now we make a copy of them. This
	  was affecting elilo when called directly from bootmanager with NVRAM options.

2001-06-28  Stephane Eranian <eranian@hpl.hp.com>
	* removed W2U() hack to get from wide-char to unicode. Use -fshort-wchar option instead.
	* split gnu-efi package in two different packages: the libary+include+crt and the bootloader.
	* restructured the fileops module. Now use direct function calls.

	* created a strops.c file to incorporate all string operations functions.
	* added support for ext2fs filesystem.
	* restructured code to allow additional filesystems to be added easily.
	* cleaned up add-on chooser interface.
	* restructured code to use the EFI protocol interface to install filesystems.
	* added compile-time options to turn on and off specific filesystems.
	* added support for architecture specific configuration options (elilo.conf).
	* added fpswa option to IA-64 to designate a fpswa driver file.
	* incoporated IA-32 support from Mike Johnston <michael.johnston@intel.com>
	* incorporated rewritten gzip.c:flush_window() from Tony Luck <tony.luck@intel.com>
	* added interface for custom device naming schemes (devnames directory).
        * added support for 2 possible config file (now just on netboot). The first
          (primary) choice uses a host specific filename based on the IP address. Suggestion
	  from Egan Ford <egan@sense.net>.

2001-04-06  Stephane Eranian <eranian@hpl.hp.com>

	* incorporated patches from David and Michael Johnston at Intel
	  to get the package to compile for IA-32 linux target.

	* Fixed ELILO to compile for Ia-32 (does not execute yet, though):
	  Makefile and start_kernel() function.

2001-04-06  Andreas Schwab <schwab@suse.de>

	* Fixed config.c  to
	  get the timeout directive to do something. implemented the global
	  root= directive.

	* Fix the efi_main() to deal with the -C option properly

2001-04-05  Stephane Eranian <eranian@hpl.hp.com>

	* update efi library to latest EFI toolkit 1.02 as distributed
	  by Intel. Fixed header + library files to compile with GCC

	* merged ELI and LILO (as of gnu-efi-1.1) together, mostly
	  taking the config file feature of ELI.

	* renamed LILO to ELILO to make the distinction

	* restructured code to make it easier to understand and maintain

	* fixed FPSWA driver checking and loading: we try all possible
	  files and let the driver itself figure out if it is the most
	  recent.
	* added support for compression (gzip) but keep support for plain
	  ELF image. ELILO autodetects the format

	* change the way the kernel is invoked. Now we call it in 
	  physical memory mode. This breaks the dependency between the
	  kernel code and the loader. No more lilo_start.c madness.

	* changed the way the boot_params are passed. We don't use the 
	  ZERO_PAGE_ADDR trick anymore. Instead we use EFI runtime memory.
	  The address of the structure is passed to the kernel in r28
	  by our convention.

	* released as gnu-efi-2.0

2001-04-03  David Mosberger  <davidm@hpl.hp.com>

	* gnuefi/reloc_ia32.c (_relocate): Change return type from "void"
	to "int".  Return error status if relocation fails for some
	reason.

	* gnuefi/elf_ia32_efi.lds: Drop unneeded ".rel.reloc" section.

	* gnuefi/crt0-efi-ia32.S (_start): Exit if _relocate() returns with
	non-zero exit status.

	* inc/ia32/efibind.h [__GNUC__]: Force 8-byte alignment for 64-bit
	types as that is what EFI appears to be expecting, despite the
	"#pragma pack()" at the beginning of the file!

2001-03-29  David Mosberger  <davidm@hpl.hp.com>

	* gnuefi/reloc_ia32.c: Add a couple of defines to work around
	libc/efilib collision on uint64_t et al.
	(_relocate): Use ELF32_R_TYPE() instead of ELFW(R_TYPE)().

	* gnuefi/crt0-efi-ia32.S (dummy): Add a dummy relocation entry.

2001-03-29  David Mosberger  <davidm@hpl.hp.com>

        * gnuefi/reloc_ia32.c: Add a couple of defines to work around
        libc/efilib collision on uint64_t et al.

 	* Make.defaults (CFLAGS): Remove -nostdinc flags so we can pick
 	up the C compiler's stdarg.h.
 
 	* inc/stdarg.h: Remove this file.  It's not correct for gcc (nor
 	most other optimizing compilers).

2000-10-10  Stephane Eranian <eranian@hpl.hp.com>

	* cleaned up the error message and printing of those.
	* added support to load the FPSWA from a file in case support is not
	  present in the firmware already
	* fixed split_args() to do the right thing when you have leading spaces
	  before kernel name
	* changed the argify() function to rely on \0 instead of LoadOptionSize
	  as the field seems to be broken with current firmware
	* bumped version to 1.0

2000-10-04  David Mosberger  <davidm@hpl.hp.com>
 
	* gnuefi/reloc_ia64.S: Reserve space for up to 750 function descriptors.

	* gnuefi/elf_ia64_efi.lds: Add .sdata section for small data and
	put __gp in the "middle" of it.

	* gnuefi/crt0-efi-ia64.S (_start): Use movl/add to load
	gp-relative addresses that could be out of the range of the addl
	offset.
	* gnuefi/reloc_ia64.S (_relocate): Ditto.

	* apps/Makefile: Remove standard rules and include Make.rules instead.

	* added exit capability just before starting the kernel

2000-06-22  David Mosberger  <davidm@hpl.hp.com>

	* gnuefi/elf_ia64_efi.lds: Add .srodata, .ctors, .IA64.unwind,
	.IA64.unwind_info to .data section and .rela.ctors to .rela
	section.

2000-04-03  David Mosberger  <davidm@hpl.hp.com>

	* lilo/lilo.c (LILO_VERSION): Up version number to 0.9.

	* gnuefi/elf_ia64_efi.lds: Include .IA_64.unwind and
	.IA_64.unwind_info in .data segment to avoid EFI load error
	"ImageAddress: pointer outside of image" error due to the .dynsym
	relocations against these sections.

	* ChangeLog: Moved from lilo/ChangeLogs.

	* gnuefi/reloc_ia64.S: fixed typo: .space directive had constant
	100 hardcoded instead of using MAX_FUNCTION_DESCRIPTORS
	macro. Duh.

Fri Mar 17 15:19:18 PST 2000 Stephane Eranian <eranian@hpl.hp.com>
