* Fixed realloc() - "size" wasn't what I thought it would be.

* When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is
held longer than DEBUG_LATENCY micro seconds (currently 200). If your system
doesn't boot anymore, a new safemode setting can disable the panic.
* Besides some problems during boot when the MTRRs are set up, 200 usecs work
fine here if all debug output is turned off (the output stuff is definitely
problematic, though I don't have a good idea on how to improve upon it a lot).
* Renamed the formerly BeOS compatible safemode settings to look better; there
is no need to be compatible there.

checked the existence of the apics.
Moved the code to disable the local apic from arch_timer.c to arch_int.cpp, so
we also avoid installing the interrupt handler for it.

Same for the IOAPIC, but commented out the code, since we're not using the
IOAPIC yet.
Also renamed the option to "Disable LOCAL APIC", since it's more correct.

* Moved device_manager/settings.cpp to debug/safemode_settings.cpp.
* Removed the somewhat hacky concatenation of kernel settings and safemode
settings in the boot loader. Instead, get_safemode_option() will now fall
back to the kernel settings, if it couldn't spot a setting in the safemode
settings. This allows for more control, and also makes enabling serial
debug output actually work (ie. overriding the kernel settings via safemode
options).
* Adjusted debug_init_post_vm(), and smp_init_other_cpus() to use
get_safemode_boolean().
* Therefore, I added safemode_settings.cpp to the boot loader as well.

Add assembler code to actually jump to the kernel.
The terminal now says:

Turn off interrupts at loader entryn and make sure the mmu is disabled.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32405 a95241bf-73f2-0310-859d-f6bbb57e9c96
Add support for boot splash, only for PXA.
Disabled for now as it forces the framebuffer onto some useful data.

Start of framebuffer initialization for the Verdex board.
For now it points to the data section as framebuffer for testing and shows an RGB pattern.

* The vesa driver no longer uses VGA programming if the chip does not support
VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
the new vesa_set_indexed_colors() that is now used for palette programming.
This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
right now, the colors are garbled after a workspace switch. Stefano, are you
looking into that already?

Update the memory map to account for passed tgz mapping. It's still hardcoded for now though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32339 a95241bf-73f2-0310-859d-f6bbb57e9c96
Actually enable mmu_init() since it works for verdex now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32338 a95241bf-73f2-0310-859d-f6bbb57e9c96
move checking for the tgz after debug init, and print something when found.

Partial implementation of mmu support for the bootloader, with lot of debugging output.

- stubbed out many arch kernel functions (borrowed from other archs),
- partially implement ELF relocations code, enough to load the kernel,
- move uart.c to kernel sources and use the same one for the loader,
- default implementation for gensyscalls,
- assembler code functions for interrupt masking (enable/disable/restore/query).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32327 a95241bf-73f2-0310-859d-f6bbb57e9c96
Stubbed out config_manager and pci bus_manager arch code.
Now really use the boot floppy tgz for the netbsd uimage as it all builds, but with other kernel arch code not yet commited.

- don't clobber the parameter regs in the entry point,
- fix entry point address for netbsd loader emulation,
- added a gUImage global to point to the uimage blob with the tgz,
- added tgz info to platform stage2 args,
- add simple uimage support, just dumps the header and gets the nth blob in the image, (seems we have a bug in the math code, some infos don't print),
- made devices.cpp use them to publish the MemoryDisk,
- add an haiku_loader_nbsd.ub target which puts both the loader and kernel_arm for now (need to replace with the tgz).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32295 a95241bf-73f2-0310-859d-f6bbb57e9c96
- cleanup,
- moved the startup asm code to u-boot/arch/arm/shell.S
- added netbsd loader entry point,
- store the invocation type (0: standalone, 1: netbsd),
- store the global data in a variable,
- added some debug code to see what U-Boot gives us.

- consolidate board specific definitions into build/jam/board/*/BoardSetup to avoid duplicating address values everywhere,
- add various addresses, boot script, custom C/C++ flags and SD card definition,
- not sure BoardSetup is included at the best place though,
- replaced board-specific ldscript with passing the loader address directly to LD from BoardSetup,
- added haiku.mmc target which generates an mmc/SD card image with a FAT partition with the files needed to boot for the board, should later be integrated with haiku.image with the BFS partition offset passed to bfs_shell, requires apt:sfdisk,mtools on GNU/Linux,
- added some more rules, one to build a script for the SD image,
- fake a NetBSD loader for now, U-Boot doesn't know haiku, and we'll need a way to pass the tgz image and RAM size, we'll either use standlone way (usual C argv[]) or the NetBSD args,
- style fixes,
- 80 cols, /me pets Ingo.
