The SPL support cannot be enabled yet, but we can add the Kconfig options in preparation for this. Signed-off-by: Simon Glass <sjg@chromium.org>

help
|
|
This config option enables Driver Model. This brings in the core
|
|
support, including scanning of platform data on start-up. If
|
|
CONFIG_OF_CONTROL is enabled, the device tree will be scanned also
|
|
when available.

bool "Enable Driver Model for SPL"

help
|
|
Enable driver model in SPL. You will need to provide a
|
|
suitable malloc() implementation. If you are not using the
|
|
full malloc() enabled by CONFIG_SYS_SPL_MALLOC_START,
|
|
consider using CONFIG_SYS_MALLOC_SIMPLE. In that case you
|
|
must provide CONFIG_SYS_MALLOC_F_LEN to set the size.
|
|
In most cases driver model will only allocate a few uclasses
|
|
and devices in SPL, so 1KB should be enable. See
|
|
CONFIG_SYS_MALLOC_F_LEN for more details on how to enable it.

config DM_WARN

bool "Enable warnings in driver model"
|
|
help
|
|
The dm_warn() function can use up quite a bit of space for its
|
|
strings. By default this is disabled for SPL builds to save space.
|
|
This will cause dm_warn() to be compiled out - it will do nothing
|
|
when called.

bool "Support device removal"
|
|
help
|
|
We can save some code space by dropping support for removing a
|
|
device. This is not normally required in SPL, so by default this
|
|
option is disabled for SPL.

bool "Support stdio registration"
|
|
help
|
|
Normally serial drivers register with stdio so that they can be used
|
|
as normal output devices. In SPL we don't normally use stdio, so
|
|
we can omit this feature.
