| * of/flattree: Don't assume HAVE_LMBJeremy Kerr2010-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | We don't always have lmb available, so make arches provide an early_init_dt_alloc_memory_arch() to handle the allocation of memory in the fdt code. When we don't have lmb.h included, we need asm/page.h for __va.

| * 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. Compiled on powerpc, with CONFIG_BLK_DEV_INITRD=y and =n. Signed-off-by: Jeremy Kerr <jeremy.kerr@canonical.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | | | | | | | | | | | | | | Microblaze only has one CPU, it isn't SMP at all. early_init_dt_scan_cpus() is effectively just a no-op, so remove it. Microblaze doesn't support hypervisor assisted dump either, so the phyp stuff can also go. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Michal Simek <monstr@monstr.eu>

| * | 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.
