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. |

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. |

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. |

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. |
