of: use __be32 for cell value accessors · 2e89e685

由 Jeremy Kerr 提交于 1月 30, 2010

Currently, we're using u32 for cell values, and hence assuming
host-endian device trees.

As we'd like to support little-endian platforms, use a __be32 for cell
values, and convert in the cell accessors.

of/flattree: use OF_ROOT_NODE_{SIZE,ADDR}_CELLS DEFAULT for fdt parsing · 36b9d307

由 Jeremy Kerr 提交于 2月 01, 2010

At present we're using hard-coded values for defaults when parsing the
FDT. This change uses the #defines instead.

of/flattree: use callback to setup initrd from /chosen · 1406bc2f

由 Jeremy Kerr 提交于 1月 30, 2010

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.

of: include linux/proc_fs.h · a9f2f63a

由 Jeremy Kerr 提交于 2月 01, 2010

We use a few procfs-specific functions (eg, proc_device_tree_*) which
aren't covered by the current includes. This causes the following build
error on arm:

drivers/of/base.c: In function 'prom_add_property':
drivers/of/base.c:861: error: implicit declaration of function 'proc_device_tree_add_prop'
drivers/of/base.c: In function 'prom_remove_property':

drivers/of/base.c: In function 'prom_update_property':
drivers/of/base.c:946: error: implicit declaration of function 'proc_device_tree_update_prop'

Add proc_fs.h for these prototypes.

of: unify phandle name in struct device_node · 6016a363

由 Grant Likely 提交于 1月 28, 2010

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.
