fdt: remove fdtdec_get_alias_node() function

2014-11-27T16:12:30+00:00

The fdt_path_offset() checks an alias too.

fdtdec_get_alias_node(blob, "foo") is equivalent to
fdt_path_offset(blob, "foo").

dm: Allow stdio registration to be dropped

2014-11-21T07:13:14+00:00

Provide a CONFIG_DM_STDIO option to enable registering a serial device
with the stdio library. This is seldom useful in SPL, so disable it by
default when building for SPL.

dm: serial: Support changing the baud rate

2014-11-21T07:10:16+00:00

Implement this feature in the uclass so that the baudrate can be changed
with 'setenv baudrate '.

dm: serial: Move current serial port pointer to global_data

2014-11-21T06:24:11+00:00

In general we can't store things in the data section until we have inited
SDRAM. Some platforms allow this (e.g. those with SPL) but some don't. Move
the pointer to global_data so that it will work on all platforms.

Without this fix the serial port will not work prior to relocation with
driver model on some platforms.

dm: serial: consolidate common code more

2014-10-24T03:43:09+00:00

Commit b8893327e9d2 (dm: serial: Put common code into separate functions)
consolidated getc() and putc().  This commit does more puts() and tsts().

Also rename locally used functions to _serial_*() for clarification
because we have similar functions names here are there in this file.

The type (void *) can be directly passed to a function that
takes a specific pointer type.

dm: serial: fix console putc

2014-10-24T03:43:08+00:00

Commit b8893327e9d2 (dm: serial: Put common code into separate functions)
consolidated getc() correctly, but introduced another bug to putc();
serial_stub_putc() passes sdev->priv to serial_putc_dev(), but
serial_putc_dev() uses cur_dev instead of the given argument.

dm: serial: Support CONFIG_CONS_INDEX if available

Try to use this option to select the correct uart for the console. This
mimics the behaviour of drivers/serial.c.

dm: serial: Reset the watchdog while waiting in getc()

2014-10-24T01:29:07+00:00

We have moved the busy-wait loop out of drivers and into the uclass. This
means that we must reset the watchdog when busy-waiting.

Note: some drivers may still have a busy-wait even with driver model, as
a transition mechanism. Driver model will tolerate this, and is can be
cleaned up when all users of the driver use driver model. An example is
ns16550.
