serial: Remove CONFIG_SERIAL_MULTI from remaining sources

2012-10-15T18:53:59+00:00

Remove the parts depending either on disabled CONFIG_SERIAL_MULTI
or ifdefs around CONFIG_SERIAL_MULTI parts since CONFIG_SERIAL_MULTI
is now enabled by default.

Fix constness of the fdt void pointer in fdt_getprop_u32_default

2011-11-13T16:21:34+00:00

The function fdt_getprop_u32_default doesn't modify the fdt, so it can use a
const void * for its fdt argument.

Add some missing endian conversions in fdt_support.c

2011-11-13T16:21:34+00:00

Some functions in fdt_support.c use fdt_getprop to read 32 bit values out of
the device tree, but then use them directly without doing any endian
conversion. Because they check for a value that doesn't actually appear in
practice, the functions continued to work even though they're incorrect.
This change adds the missing conversions.

fdt: Add new fdt_set_node_status & fdt_set_status_by_alias helpers

2011-10-18T05:36:55+00:00

Add common function fdt_set_node_status() to assist in various locations
that we set a nodes status.  This function utilizes the status values
that are part of the EPAPR spec (on power.org).

fdt_set_status_by_alias() is based on fdt_set_node_status() but uses an
alias string to identify the node to update.

We also add some shortcut functions to help the common cases of setting
"okay" and "disabled":

	fdt_status_okay()
	fdt_status_disabled()
	fdt_status_okay_by_alias()
	fdt_status_disabled_by_alias()

Finally, we fixup the corenet_ds ethernet code which previously had
a function by the same name that can be replaced with the new helpers.

fdt: update fdt_alloc_phandle to use fdt_get_phandle

2011-10-15T13:35:09+00:00

The device tree compiler, dtc, can use "phandle" and/or "linux,phandle"
properties to specify the phandle for any node.  By default, it uses
both, but "linux,phandle" is deprecated.  One day, we'd like to stop using
"linux,phandle", but U-boot needs to support both properties equally
first.

fdt_alloc_phandle() generates a unique phandle, but it was only checking
the "linux,phandle" properties.  Instead, we use fdt_get_phandle(),
which checks both properties automatically.  This ensures that we
support dtbs that only use "phandle".

The side-effect is that fdt_alloc_phandle() now takes twice as long, since
it has to check for two properties instead of one in each node that it
searches.

fdt: check for fdt errors in fdt_create_phandle

2011-10-15T13:35:00+00:00

fdt_create_phandle() was ignoring errors from fdt_set_phandle().  If an
error occurs, print an error message and return 0, which is an invalid
phandle.  We also need to change the return type for fdt_create_phandle()
to indicate that it cannot return an error code.

fdt: Add new fdt_create_phandle helper

2011-09-30T00:01:05+00:00

Add a helper function that will return a phandle value for the given
node.  If the node doesn't have a phandle already one will be created.

fdt: Rename fdt_create_phandle to fdt_set_phandle

2011-09-30T00:01:05+00:00

The old fdt_create_phandle didn't actually create a phandle it just
set one.  We'll introduce a new helper that actually does creation.
