fdt_support: Add a fdt_setup_simplefb_node helper function

2014-11-25T12:38:46+00:00

Add a generic helper to fill and enable simplefb nodes.

The first user of this will be the sunxi display code.

lcd_dt_simplefb_configure_node is also a good candidate to be converted
to use this, but that requires someone to run some tests first, as
lcd_dt_simplefb_configure_node does not honor #address-cells and #size-cells,
but simply assumes 1 and 1 for both.

fdt: Add ft_system_setup() function for system device tree additions

2014-11-21T03:43:18+00:00

Add an additional function for adding information to the device tree before
booting. This permits additions which are not board-specific.

fdt: Tidy up error handling in image_setup_libfdt()

2014-11-21T03:43:17+00:00

The message about needing to reset should be printed no matter what error
is printed. Also, an error should always be printed.

fdt: Export the fdt_find_or_add_subnode() function

2014-11-21T03:43:17+00:00

This function is useful for ensuring that a node exists. Export it so it
can be used more widely.

fdt: Allow ft_board_setup() to report failure

2014-11-21T03:43:15+00:00

This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.

Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.

Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

fdt_support: Make of_bus_default_count_cells non static

2014-09-25T15:36:19+00:00

of_bus_default_count_cells can be used to get the #address-cells
and #size-cells defined by the current node's parent node. This
is required when using of_read_number to read from FDT nodes that
can be 32 or 64 bytes depending on values defined by the parent.

fdt_support: Move of_read_number to fdt_support.h

2014-09-25T15:36:19+00:00

This is being done so that it can be used outside 'fdt_support.c'. Making
life more convenient when reading device node properties that can be 32
or 64 bits long.

fdt: Rename fdt_resize() to fdt_shrink_to_minimum()

2014-08-09T15:17:03+00:00

Since libfdt now has an fdt_resize() function, we need to rename the
U-Boot one.
