This is especially important for the assembler code in the kernel,
since it enables workarounds for some critical errata related to
exception handling.
* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).
An archive (ramfs) to be loaded can be specified in the raspberry pi
config.txt with a certain base address. We can use this to put our
floppy boot archive into memory on startup.
During the start procedure we now map that archive so we can later
load the kernel from it.
* our current gcc can't be built with multilib for ppc anyway,
* this allows going further on real hardware, though dprintf() sends wrong data to the serial port.
* since we include BoardSetup earlier now, the TARGET_* flags were discarded. Use HAIKU_* instead.
* Add variables to hold the default entry point and the desired uimage OS emulation.
* Pi firmware was updated to note that Broadcom
had to be included with firmware blobs.
* While we have permission from Eben to have the
blobs in-tree, they are now offically on github
in a fixed location removing the need to have
these in-tree.
* Clean up BoardConfig, note firmware URL and
files needed
* Update info.txt with how Haiku boot process works
* Thanks go out to Simon Arlott for replacing
the first32k.bin blob with assembly removing
the need for first32k.bin hack.
* This assembly is a modified version removing
the Linux kernel boot args.
* haiku_loader renamed to kernel.img will boot
on Raspberry Pi directly.
* Version 17-02-2012
* Used to initialize the Raspberry Pi GPU and boot it
* License is permissive, I've also included the
confirmation email on this license.
* Little bootloader documentation.
* Still nothing to get excited about, preliminary.
Workaround for ld using 32k alignment between ELF segments, until a proper fix is found.

- 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).

- 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.
