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!

[ARM] 3377/2: add support for intel xsc3 core Patch from Lennert Buytenhek This patch adds support for the new XScale v3 core. This is an ARMv5 ISA core with the following additions: - L2 cache - I/O coherency support (on select chipsets) - Low-Locality Reference cache attributes (replaces mini-cache) - Supersections (v6 compatible) - 36-bit addressing (v6 compatible) - Single instruction cache line clean/invalidate - LRU cache replacement (vs round-robin) I attempted to merge the XSC3 support into proc-xscale.S, but XSC3 cores have separate errata and have to handle things like L2, so it is simpler to keep it separate. L2 cache support is currently a build option because the L2 enable bit must be set before we enable the MMU and there is no easy way to capture command line parameters at this point. There are still optimizations that can be done such as using LLR for copypage (in theory using the exisiting mini-cache code) but those can be addressed down the road.

[ARM] nommu: adjust headers for !MMU ARM systems Majorily based on Hyok Choi's patches, this fixes up the asm-arm header files for mmuless systems. Over and above Hyok's patches: - nommu.h merged into mmu.h (it's only a structure) - nommu_context.h is essentially the same as mmu_context.h, but without the MM switching code. so there's no point having separate files. Also, in memory.h, there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the configuration scripts. Other files have minor formatting changes, but are essentially the same. Hyok's original patches were signed off thusly: Signed-off-by: Hyok S.
