 - drivers/tty/serial/8250.c
	moved UPIO_TSI to powerpc vs removed UPIO_DWAPB support

dt: add of_alias_scan and of_alias_get_id

2011-09-22T17:12:10+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.

v3: Split out automatic addition of aliases on id lookup so that it can be
    debated separately from the core functionality.
v2: - Add of_chosen/of_aliases populating and of_alias_scan() invocation
    for OF_PROMTREE.
    - Add locking
    - rework parse loop

of: Change logic to overwrite cmd_line with CONFIG_CMDLINE

2011-09-20T06:09:34+00:00

We used to overwrite with CONFIG_CMDLINE if we found a chosen
node but failed to get bootargs out of it or they were empty,
unless CONFIG_CMDLINE_FORCE is set.

Instead change that to overwrite if "data" is non empty after
the bootargs check. It allows arch code to have other mechanisms
to retrieve the command line prior to parsing the device-tree.

Note: CONFIG_CMDLINE_FORCE case should ideally be handled elsewhere
as it won't work as it-is if the device-tree has no /chosen node

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/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.
