dm: core: Add a function to bind child devices

2016-07-27T20:14:37+00:00

We currently use dm_scan_fdt_node() to bind devices. It is an internal
function and it requires the caller to know whether we are pre- or post-
relocation.

This requirement has become quite common in drivers, so the current function
is not ideal.

Add a new function with fewer arguments, that does not require internal
headers. This can be used directly as a post_bind() method if needed.

dm: core: Don't use device tree with of-platdata

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

When CONFIG_SPL_OF_PLATDATA is enabled we should not access the device
tree. Remove all references to this in the core driver-model code.

dm: add manual relocation for devices

2016-06-19T23:05:55+00:00

Some architectures as m68k still need to use CONFIG_NEEDS_MANUAL_RELOC,
and are not still using the device tree.

dm: core: Add option to configure an offset for the address translation

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

Some platforms need to ability to configure an offset to the standard
addresses extracted from the device-tree. This patch allows this by
adding a function to DM to configure this offset (if needed).

dm: core: Add missing entries for manual relocation

"dm: core: Allow uclass to set up a device's child before it is probed"
(sha1: 83c7e434c9dd3ca81f8b763e23c1881b973bcf2f)

Adds new entries to struct driver and struct uclass_driver without
extending code for manual relocation. This patch fixes it for all
architectures which requires MANUAL_RELOC.

dm: Provide better debugging when a device fails to bind

2015-09-03T03:28:23+00:00

All devices should bind without error. But when they don't, they can cause
driver model init to fail. A real situation where this can happen is when
there is a missing uclass.

Add a debug() call to dm_scan_fdt_node to make this easier to track.

of: clean up OF_CONTROL ifdef conditionals

2015-08-18T17:46:05+00:00

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

dm: core: Select device tree control correctly for SPL

2015-04-23T15:05:54+00:00

Some boards will not use device tree for SPL even with driver model. Add
the logic to support this.

dm: Add support for all targets which requires MANUAL_RELOC

2015-02-12T22:17:29+00:00

Targets with CONFIG_NEEDS_MANUAL_RELOC do not use REL/RELA
relocation (mostly only GOT) where functions aray are not
updated. This patch is fixing function pointers for DM core
and serial-uclass to ensure that relocated functions are called.
