Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

MIPS: Add uImage build target Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot image of vmlinux.bin.gz), and then symlinks it to uImage. This allows for the use of other compression algorithms in future, and is how a few other architectures do it. It's enabled conditionally on load-y >= 0xffffffff80000000 which hopefully allows 64bit kernels to also work as long as the load and entry address can be represented by the 32bit addresses in the U-Boot image format.

UPSTREAM: MIPS: Support generating Flattened Image Trees (.itb) Add support for generating kernel images in the Flattened Image Tree (.itb) format as supported by U-Boot. This format is essentially a Flattened Device Tree binary containing images (kernels, DTBs, ramdisks) and configurations which link those images together. The big advantages of FIT images over the uImage format are: - We can include FDTs in the kernel image in a way that the bootloader can extract it & manipulate it before providing it to the kernel. Thus we can ship FDTs as part of the kernel giving us the advantages of being able to develop & maintain the DT within the kernel tree, but also have the benefits of the bootloader being able to manipulate the FDT. Example uses for this would be to inject the kernel command line into the chosen node, or to fill in the correct memory size. - We can include multiple configurations in a single kernel image. This means that a single FIT image can, given appropriate bootloaders, be booted on different boards with the bootloader selecting an appropriate configuration & providing the correct FDT to the kernel. - We can support a multitude of hashes over the data.

UPSTREAM: MIPS: generic: Introduce generic DT-based board support Introduce a "generic" platform, which aims to be board-agnostic by making use of device trees passed by the boot protocol defined in the MIPS UHI (Universal Hosting Interface) specification. Provision is made for supporting boards which use a legacy boot protocol that can't be changed, but adding support for such boards or any others is left to followon patches. Right now the built kernels expect to be loaded to 0x80100000, ie. in kseg0. This is fine for the vast majority of MIPS platforms, but nevertheless it would be good to remove this limitation in the future by mapping the kernel via the TLB such that it can be loaded anywhere & map itself appropriately. Configuration is handled by dynamically generating configs using scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc makes use of it. This allows for variations upon the configuration, eg. differing architecture revisions or subsets of driver support for differing boards, to be handled without having a large number of defconfig files.
