- 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
- Fix bad heuristic in mkelfImage 1.11 where if I wasn't given a firmware
type I assumed PCBIOS.
- Use objcopy to strip off extra symbols and the .ramdisk section if unused
- Fix typo linuxBIOS -> LinuxBIOS
ELF notes especially an ELF checksum of the entire image. This finishes
my proof of concept implementation of all significant features with respect
to ELF booting. Now to do some native ports...
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.
This also includes a bunch of my pending work including
- Updated serial code so we can compile in different serial port speeds
- Updates to the build system so that:
- Makefile.settings holds all of the settings of the config variables
- ldoptions and cpuflags are generated automatically with perl scripts
- src/config/Config holds all of the architecture neutral make file settings
- Initial work on the P4 including how to use cache as ram
- Update to the ioapic code for the P4 because it delivers irqs on the system
bus instead of an out of band bus
- Updated version of printf that doesn't need an intermediate buffer
- logbuf_subr now handles the case when we want to use a log buffer
- video_subr handles the preliminary code for writing to a video device.
- Pending changes for the L440GX are merged in as well (hopefully I haven't
messed then up since they were written).
Add rule for ldscript.ld
printk.h
Fix typo it should be printk_alert not printk_alart...
NLBConfig.py
- Removed some dead code
- Modified mainboardinit and ldscript to act like my recently modified
object command and take as a suffix a config option that must be
set to one for them to work.
- No longer generate ldscript.ld instead generate ldoptions and
the variable LDSUBSCRIPTS-1.
crt0.base
- SMP compile fixes
- No longer unconditionally include cpu/p5/start32.inc
(it's been renamed cpu/i386/entry16.inc)
ldscript.base
- Simplfied, and moved some content into reset16.lds and entry16.lds
stddef.h
- Use C style comments for #endif /* I386_STDDEF_H */
pirq_routing.h
- The define is HAVE_PIRQ_TABLE not HAVE_PIRQ_ROUTING_TABLE
mtrr.c
- Remove the need for defining INTEL_PPRO_MTRR
mainboard/xxx/Config
- start32.inc is no longer automatically included include
entry16.inc and reset16.inc where appropriate
In particular if we are using a docipl we don't want
reset16.inc or reset16.lds
tyan/guiness/mptable.c
- Removed spurious define USE_ALL_CPUS
northbridge/intel/440gx/
- Updated to compile with the factored generic memory code.
nortsouthbridge/sis/xxx/
- Remove includes of northsouthbridge/sis/630/param.h did I add them?
The file is gone now so including it is just bad...
NLBConfig.py
- Allow relative filename arguments
- Add directive ldscript to add an include file into
our linker script
- Fixed docipl to use strings when calling set_option
- Allow target the target directive to use relative paths
- Add extra dependencies to ldscript.lds
