| * microblaze: Fix dma alloc and free coherent dma functionsMichal Simek2010-03-11
| | | | | | | | | | | | | | | | | | | | We have to use consistent code to be able to do coherent dma function. In consistent code is used cache inhibit page mapping. Xilinx reported that there is bug in Microblaze for WB and d-cache_always use option. Microblaze 7.30.a should be first version where is this bug removed.

| | | | | | | | | | | | | | | | | | | | For copy was used r7 register when CONFIG_CMDLINE_BOOL option is enabled. But r7 stores pointer to fdt that's why machine_early_init not detect compiled-in DTB. I also moved kernel PID setup to have TLB init in one block Signed-off-by: Michal Simek <monstr@monstr.eu>

| * microblaze: Add support for Xilinx PCI host bridgeMichal Simek2010-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on powerpc patch 64f16502475ddf663169369fffff6da9b10ea9fb We did some cleanups and removed powerpc parts. There is one new debug early listing function too. Exclude function is only in Debug options. We tested in on custom board. Signed-off-by: Michal Simek <monstr@monstr.eu>

| * microblaze: Support DMAMichal Simek2010-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add DMA support for Microblaze. There are some part of this new feature: 1. Basic DMA support 2. Enable DMA debug option 3. Setup notifier Ad 1. dma-mapping come from powerpc and x86 version and it is based on generic dma-mapping-common.h Ad 2. DMA support debug features which is used in generic file. For more information please look at Documentation/DMA-API.txt Ad 3. notifier is very important to setup dma_ops. Without this part for example ll_temac driver failed because there are no setup dma operations. Signed-off-by: Michal Simek <monstr@monstr.eu>
* | microblaze: use generic ptrace_resume codeChristoph Hellwig2010-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT and PTRACE_KILL. This also makes PTRACE_SINGLESTEP return -EIO while it previously succeeded despite not actually causing any kind of single stepping. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code.

|/ | | | | | | | | | | | | | | | | | | | | Use ptrace_request() in the three remaining architectures that didn't use it (m68knommu, h8300, microblaze). This means: - ptrace_request now handles PTRACE_{PEEK,POKE}{TEXT,DATA} and PTRACE_DETATCH calls that were previously called directly, or in case of h8300 even open coded. - adds new support for PTRACE_SETOPTIONS/PTRACE_GETEVENTMSG/ PTRACE_GETSIGINFO/PTRACE_SETSIGINFO Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Michal Simek <monstr@monstr.eu> Acked-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Roland McGrath <roland@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * of/flattree: use callback to setup initrd from /chosenJeremy Kerr2010-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, the fdt code sets the kernel-wide initrd_start and initrd_end variables when parsing /chosen. On ARM, we only set these once the bootmem has been reserved. This change adds an arch hook to setup the initrd from the device tree: void early_init_dt_setup_initrd_arch(unsigned long start, unsigned long end); The arch-specific code can then setup the initrd however it likes.

| * | of: unify phandle name in struct device_nodeGrant Likely2010-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.
