| * [ARM] 3061/1: cleanup the XIP link address messNicolas Pitre2005-10-294-52/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre Since vmlinux.lds.S is preprocessed, we can use the defines already present in asm/memory.h (allowed by patch #3060) for the XIP kernel link address instead of relying on a duplicated Makefile hardcoded value, and also get rid of its dependency on awk to handle it at the same time. While at it let's clean XIP stuff even further and make things clearer in head.S with a nice code reduction.

| * [ARM] 3060/1: allow constants found in asm/memory.h to be used in asm codeNicolas Pitre2005-10-293-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre This patch allows for assorted type of cleanups by letting assembly code use the same set of defines for constant values and avoid duplicated definitions that might not always be in sync, or that might simply be confusing due to the different names for the same thing.

| | | | | | | | | | | | | | | | Prefetching may be fatal on some systems if we're prefetching beyond the end of memory on some systems. It's also a seriously bad idea on non dma-coherent systems. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* | pci-expmem-hackAndrew Isaacson2005-10-291-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | CFE 1.2.5 and earlier fails to turn on the ExpMemEn bit in the PCIFeatureControl register, which means that DMA does not work beyond physical address 01_0000_0000, ergo to DRAM beyond 1GB. With ExpMemEn turned on, 01_0000_0000-0f_ffff_ffff is mapped, so DMA works for up to 61 GB of DRAM. Will be fixed in CFE 1.2.6 (yet to be released).
