option USE_DOC_MIL=1
now, not just
option USE_DOC_MIL
The latter usage led to empty streams struct.
This is a real problem, though: you can no streams for reading and the linker
will happily create an empty streams structure. Which sucks, since you don't know
why your system won't boot.
Not really needed, but in the BIOS paranoia is a healthy frame of mind.
Added some debug prints to newpci.c
Fixed sbc710 Config to ensure that com1 and com2 are enabled
(input still does not work)
Changed
extern struct ... *all_superio in hardwaremain.c to
extern struct ... all_superio[] to avoid gcc dereferencing the pointer
(when did THIS C behavior change go in?)
- Workaround cmos tables overlapping the traditional bios data segment
- Fixes to the p4dc6 examples to be syntactically correct
- Fixes to NLBConfig to fix the previos syntax error ``option foo bar'' is invalid
- Update docmil_fil_inbuf to only be compiled when the appropriate options are set
- Updates NLBConfig.py to export the variables MAINBOARD && TARGET_DIR
as well as correct specify the generated files
- small bug fixes to the elf bootloader
- factor the elf bootloader into focused smal subroutines that are easier to comprehend
and maintain
- Implement support for PT_NOTE headers and parsing ELF notes if we need special functionality
An ELF Image should never need an ELF loader to interpret an ELF to work correctly, making
interpretation of all ELF notes optional.
- Implement support for notes giving PROGRAM_NAME, PROGRAM_VERSION, and PROGRAM_CHECKSUM
Highlights:
- elfboot.c Now can load images to the ram location where linuxBIOS is running
- Added the standalone directory for bootloaders built from the linuxBIOS source
Other things:
- Correctly maode fallback_boot.c conditional
- Added entry32.lds to do the math for segment descriptor table entries
- Merged ldscript.cacheram and ldscript.base
- Moved assembly code to the sections .rom.text and .rom.data
- Modified linuxBIOS so C code completely runs from RAM as the SiS630
case does
- Updated and commented example config files for the supermicro p4dc6
- Bumped the elfboot loader version to 1.0
- Removed extra carriage returns in dump_northbridge.inc (DOS->UNIX)
- General cleanups to the config of the supermicro p4dc6
- Implement payload so it attempts no processing of the image (I can now use it for ELF images!)
- Implement linux so it does what it has always done (but is now distinct from payload)
- Implement the new expr command so I can compute values (I got inspired)
- Micro fix to rom_fill_inbuf.c so we don't get back too many bytes (Thanks Ron)
- Fix for fallback_boot.c so it is always available. Otherwise I can't say my boot succeeded.
- Added example config scripts for the p4dc6
uniform_boot work, but relocated. You need the new mkelfImage to
use the elf boot format.
Previous tables were updated so I could find both the start and
the end of where they were written in memory.
Minor p4dc6 updates, to disable some debugging code.
The mkelfImage-1.9 is checked in as util/mkelfImage
and a bunch of generic changes.
- Started playing with automatic scanning memory for LinuxBIOS tables.
- Converted the fill_inbuf drivers to stream drivers. This allows
for pure data copying operations to be faster, and it allows skipping
of unneeded data on platforms that support it.
- Added a section .rodata.streams for the stream driver control structures.
This is preparation for building a bootloader that shares source code
with LinuxBIOS.
- Added a driver command to NLBConfig.py for objects that should
always be linked into LinuxBIOS if they are compiled at all.
- Moved the boot_successful logic down into the guts of the
bootloaders.
- Modified the ip style checksum logic so it isn't specific to uniform
boot headers...
- Added a function ndelay that uses the RTC (this is i786 specific for now).
- Added a function to delay in seconds for the braindead harddrive
spinup logic.
- Added a floppy stream driver.
- Added a ide stream driver.
- Broke out the ram initialization for the p4dc6 into multiple c files.
- Stupidly adapted linuxbiosmain and do_inflate to the new stream
interface. get_byte is now a slow function call so it might be able
to use some optimization.
- Updated the ELF bootloader to the new stream interface and adding a
ELF header scanning function so we can boot off of harddrives and
not smash their partition tables.
- Removed some bogus unlook ahead code from inflate.c
- Fixed a problem where we did not enable I/O resources on VGA
compatible chips. This caused a trident card to lock up the system
when it's memory mapped resources were enabled.
- Correctly set up nested pci busses. Before this a pci bus behind a
pci bus would not get enabled.
- Config changes to the p4dc6
- Added more interrupt sources to the p4dc6 interrupt table
- Converted all of the inbuf drivers to stream drivers.
All have good conversions except the doc_millenium.
