Revert "dt: add of_alias_scan and of_alias_get_id"

2011-08-04T10:26:24+00:00

This reverts commit 750f463a749e28464151ad26938d11b07b1c43cb.

of_alias_* still needs work to be generalized for 'promtree' dt
platforms, and to no implicitly create entries for available ids.

dt: add of_alias_scan and of_alias_get_id

2011-08-03T12:02:31+00:00

The patch adds function of_alias_scan to populate a global lookup
table with the properties of 'aliases' node and function
of_alias_get_id for drivers to find alias id from the lookup table.

dt/flattree: explicitly pass command line pointer to early_init_dt_scan_chosen

2011-05-11T12:53:18+00:00

This patch drops the reference to a global 'cmd_line' variable from
early_init_dt_scan_chosen, and instead passes the pointer to the command
line string via the *data argument.  Each architecture does something
slightly different with the initial command line, so it makes sense for
the architecture to be able to specify the variable name.

dt/flattree: Return virtual address from early_init_dt_alloc_memory_arch()

2011-01-16T05:01:58+00:00

The physical address is never used by the device tree code when
allocating memory for unflattening.  Change the architecture's alloc
hook to return the virutal address instead.

of/flattree: Add of_flat_dt_match() helper function

2011-01-01T20:03:25+00:00

This patch adds of_flat_dt_match() which tests a node for
compatibility with a list of values and converts the relevant powerpc
platform code to use it.  This approach simplifies the board support
code a bit.

of/flattree: Refactor unflatten_device_tree and add fdt_unflatten_tree

2010-12-30T00:02:15+00:00

unflatten_device_tree has two dependencies on things that happen
during boot time.  Firstly, it references the initial device tree
directly. Secondly, it allocates memory using the early boot
allocator.  This patch factors out these dependencies and uses
the new __unflatten_device_tree function to implement a driver-visible
fdt_unflatten_tree function, which can be used to unflatten a
blob after boot time.

V2:
- remove extra __va() call
- make dt_alloc functions return void *.  This doesn't fix the general
  strangeness in this code that constantly casts back and forth between
  unsigned long and __be32 *

of/flattree: Refactor unflatten_dt_node

2010-12-29T23:53:55+00:00

unflatten_dt_node is a helper function that does most of the work to
convert a device tree blob into tree of device nodes.  This code
now uses a passed-in blob instead of using the single boot-time blob,
allowing it to be called in more contexts.
