dm: core: Implement live tree 'read' functions

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

When the live tree is supported some functions need to change a little.
Add an implementation which is used when not inlining these functions.

dm: core: Add a place to put extra device-tree reading functions

2017-06-01T13:03:07+00:00

Some functions deal with structured data rather than simple data types.
It makes sense to have these in their own file. For now this just has a
function to read a flashmap entry. Move the data types also.

dm: core: Add livetree address functions

2017-06-01T13:03:07+00:00

Add functions to access addresses in the device tree. These are brought
in from Linux 4.10.

Also fix up the header guard for fdtaddr.h to avoid confusion.

dm: core: Add operations on device tree references

2017-06-01T13:03:07+00:00

Since U-Boot supports both a live tree and a flat tree, we need an easy
way to access the tree without worrying about which is currently active.
To support this, U-Boot has the concept of an ofnode, which can refer
either to a live tree node or a flat tree node.

For the live tree, the reference contains a pointer to the node (struct
device_node *) or NULL if the node is invalid. For the flat tree, the
reference contains the node offset or -1 if the node is invalid.

Add a basic set of operations using ofnodes. These are implemented by
using either libfdt functions (in the case of a flat DT reference) or
the live-tree of_...() functions.

Note that it is not possible to have both live and flat references active
at the same time. As soon as the live tree is available, everything in
U-Boot should switch to using that. This avoids confusion and allows us to
assume that the type of a reference is simply based on whether we have a
live tree yet, or not.

dm: core: Add livetree access functions

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

Add a basic assortment of functions to access the live device tree. These
come from Linux v4.9 and are modified for U-Boot to the minimum extent
possible. While these functions are now very stable in Linux, it will be
possible to merge in fixes if needed.

dm: core: Move dev_get_addr() etc. into a separate file

2017-06-01T12:57:52+00:00

Move this group of address-related functions into a new file. These use
the flat device tree. Future work will provide new versions of these which
can support the live tree.

dm: core: Add SPL Kconfig for REGMAP and SYSCON

2015-12-01T15:07:22+00:00

Add SPL Kconfig for REGMAP and SYSCON, so REGMAP and SYSCON can
remove from SPL stage.

dm: core: Add Kconfig for simple bus driver

2015-08-31T13:57:26+00:00

Add Kconfig entries for the simple-bus driver, both for U-Boot
and for SPL. The simple-bus is enabled by default in U-Boot and
disabled by default in SPL to preserve the original behavior.

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: drop CONFIG_DM_DEVICE_REMOVE from uncmd list

2015-08-18T17:46:04+00:00

We do not want to compile the DM remove code for SPL.  Currently,
we undef it in include/config_uncmd_spl.h (for C files) and in
scripts/Makefile.uncmd_spl (for Makefiles).  This is really ugly.

This commit demonstrates how we can deprecate those two files.

Use $(SPL_) for the entry in the Makfile and CONFIG_IS_ENABLED()
in C files.
