Move the unwind data out of the bss section, it broke bss init which ended up erasing real data and making dprintf do weird things...

- 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).

- 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.

Missed this one in previous commit: remove board.ld include as we now give LD the address directly.

- 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.

Condition the exclusive ops to >= armv6 instead of specific version.

Stub out swap funcs for pre armv6 which lack REV/REV16. WRITEME.

Temporary (?) solution to linking the loader: generate symbols needed by the unwinding code, which should actually not be used since we disable exceptions...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32239 a95241bf-73f2-0310-859d-f6bbb57e9c96
Add an __ARM_ARCH__ macro defined to the arch version to simplify checks for >= some version.

Add rule to handle uimage, and board-specific stuff to handle load addresses. Need to fix them, u-boot doesn't like loading the file with the header where the header says it should go, must copy to a different address.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32214 a95241bf-73f2-0310-859d-f6bbb57e9c96
Include board-specific file from the u-boot ldscript, to allow linking to different load addresses.

Move uart.c to arch/arm/ where it belongs, it has nothing u-boot specific.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32203 a95241bf-73f2-0310-859d-f6bbb57e9c96
- cleanup,
- add an uart_debug_port() to avoid using the #define in serial.cpp,
- use board_config defines in uart.c.

- moved board/ folder around again, it probably belongs only to kernel stuff,
- added board_config.h templates for gumstix boards.

Since we don't support Flattened Device Trees yet (and they don't solve all the issues), we need a place to hole board-specific config, which are different even though we use U-Boot on ARM. Things like cpu & mmu type...
U-Boot doesn't really help us there anyway, it only passes a few board infos (RAM banks & the bill), and optionally other stuff if we fake a linux kernel or netbsd loader, but still not enough. FDT support isn't available for ARM in U-Boot yet either. So for now, and likely for stuff we can't get from FDT, we'll put board-specific config there.
Unlike desktop machines were we want a single kernel per arch, we'd rather have the kernel built for a single board without having to handle detecting mmu type at boot and switching calls like I did on m68k.

Added a -s option to get the string value of the setting directly instead of interpreting it as bool.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32086 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added some multiboot support code:
- dump some of the passed info,
- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

- stubbed out arch_cpu_init_percpu(),
- make atomic ops declarations extern "C",
- move calls to [i]sync inside the asm code that needs it.

Based on a patch from Dustin Howett, reworked, and help from Vladimir 'phcoder' Serbinenko.
- used defines for clarity, the rest of teh code could make use of them too...
- added a gMultiBootInfo pointer to the passed args, to let C code handle it instead of faking the boot drive ID,
- conditionalized the copy back, maybe we can get rid of it when QEMU handles our default load address correctly,
- added video mode info to ask for 1024x768 but QEMU ignores it anyway, and we might need to show the menu, so it's disabled.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32059 a95241bf-73f2-0310-859d-f6bbb57e9c96
- include a config file if exists to avoid committing config stuff.

- add mention of libc6-dev-i386 which I had to install on a 64bit server,
- fix a typo.

- move gBoot* out of the boot sector,
- fix the FAT params to actually indicate 1.44kB floppy,
- fix the FloppyDrive class to also use 18 sectors/track, so now tarfs won't get data from start of disk when on the middle.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30481 a95241bf-73f2-0310-859d-f6bbb57e9c96
- loop on Floprd() alternating sides every sect/track, currently hardcoded from the FAT bootblock as probing like the NetBSD loader asserts ARAnyM,
- print a dot / sector read in the great tradition of bootloaders,
- set gBootedFromImage correctly,
- fix the script, make it jam later on.

- inline acronym definitions and remove the dotted underline
- inline urls for a tags with printurl class (we don't want all of them printed)
- noprint class for things we might not want to print at all
