serial: make serial_stub_* to static functions

2017-07-06T17:09:35+00:00

Add missing static to serial_stub_puts().

Unexport serial_stub_{getc,tstc} because they are used locally.

dm: core: Update lists_bind_fdt() to use ofnode

2017-06-01T13:03:08+00:00

Adjust this function to use an ofnode instead of an offset, so it can be
used with livetree. This involves updating all callers.

serial: serial-uclass: Use force parameter in stdio_deregister_dev()

2017-05-17T09:13:06+00:00

On my x86 platform I've noticed, that calling dm_uninit() or the new
function dm_remove_devices_flags() does not remove the desired device at
all. Debugging showed, that the serial uclass returns -EPERM in
serial_pre_remove(). This patch sets the force parameter when calling
stdio_deregister_dev() resulting in a removal of the device.

Convert CONFIG_SYS_STDIO_DEREGISTER to Kconfig

2016-10-23T22:34:17+00:00

This converts the following to Kconfig:
   CONFIG_SYS_STDIO_DEREGISTER

This option should never be enabled in SPL, so use
CONFIG_IS_ENABLED(SYS_STDIO_DEREGISTER) when checking the option.

dm: serial: Add support for of-platdata

2016-07-15T02:40:24+00:00

When this feature is enabled, we cannot access the device tree to find out
which serial device to use. Just use the first serial driver we find.

x86: Allow use of serial soon after relocation

2016-03-17T02:27:24+00:00

At present on x86 machines with use cache-as-RAM, the memory goes away just
before board_init_r() is called. This means that serial drivers are
no-longer unavailable, until initr_dm() it called, etc.

Any attempt to use printf() within this period will cause a hang.

To fix this, mark the serial devices as 'unavailable' when it is no-longer
available. Bring it back when serial_initialize() is called. This means that
the debug UART will be used instead for this period.

dm: serial-uclass: Move a carriage return before a line feed

2016-03-14T21:34:50+00:00

In general, a carriage return needs to execute before a line feed. The
patch is to change serial DM driver serial-uclass.c based on this rule.

dm: serial: Allow the UART driver to be dropped from the image

2016-01-12T17:19:09+00:00

In very very space-constrained devices even the full UART driver is too
large. In this case the debug UART can still be used in some cases.

Add options to enable the UART driver in SPL and U-Boot proper. Enable both
options by default.

dm: serial: Deal with stdout-path with an alias

2015-11-04T13:49:52+00:00

Sometimes stdout-path contains a UART alias along with speed, etc. For
example:

	stdout-path = "serial0:115200n8";

Add support for decoding this.
