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
make.base -- renamed OBJECTS to OBJECTS-1 to allow conditional compilation of objects
ldscript.base -- realized that assignemnts to the location counter inside of sections
are relative to their start so simplfied the code
pirq_routing.h -- includeded types.h so we don't have suprises
hardwaremain.c -- unconditionally included arch/smp/mpsec.h
arch/i386/smp/Config introduced conitional on the compilation objects into
the compilation process
ioapic.c -- removed (now) unneeded ifdef around this file
mpsec.c -- removed (now) unneeded ifdef around this file
cpu/cpufixup.h -- Fix typo in the case when no cpufixup is needed.
parts/framebuffer.h -- Added a missing semicolon.
smp/atomic.h -- renamed second atmoic_inc to atomic_dec oops.
tyan/guinnes/Config -- reordered the options so they are grouped a little
better and said mptable.o is dependent on HAVE_MP_TABLE
tyan/guiness/mainboard.c -- small change for clarity.
northsouthbridge/sis/630/northbridge.c
northsouthbridge/sis/630/southbridge.c
-- Remove unused include of the now dead param.h
NLBConfig.py
-- Only include numeric options in the linker script
-- Update to handle adding a condition for when to build
objects
newpci.c has some new functions. asus config is fixed for i386 stuff.
NLBconfig has a new command (nsuperio) and will take arch, mainboard, or
target as the first command. sis 950 superio has changes for the new
superio model
First, grow heap size in src/arch/i386/config/ldscript.base for DoC
Minor include fixes
Fixes to cua -- but it's now broken, won't find IDE
Minor fix to util/config/NLBConfig.py: for docipl, use CFLAGS
Added files so that CUA works with config tool.
