18e69a35ef 83xx/fdt_support: let user specifiy FSL USB Dual-Role controller role
Linux understands "host" (default), "peripheral" and "otg" (broken).
Though, U-Boot doesn't restrict dr_mode variable to these values (think
of renames in future).

43ddd9c820 Remove deprecated CONFIG_OF_HAS_UBOOT_ENV and CONFIG_OF_HAS_BD_T
These defines embedded the u-boot env variables and/or the bd_t structure
in the fdt blob.  The conclusion of discussion on the u-boot email list
was that embedding these in the fdt blob is not useful: there are better
ways of passing the data (in fact, the fdt blob itself replaces the
bd_t struct).

The only board that enables these is the stxxtc and they don't appear
to be used by linux.

b8ec238503 85xx: add ability to upload QE firmware
Define the layout of a binary blob that contains a QE firmware and instructions
on how to upload it.  Add function qe_upload_firmware() to parse the blob and
perform the actual upload.  Add command-line command "qe fw" to take a firmware
blob in memory and upload it.  Update ft_cpu_setup() on 85xx to create the
'firmware' device tree node if U-Boot has uploaded a firmware.  Fully define
'struct rsp' in immap_qe.h to include the actual RISC Special Registers.

b60af3d4c1 Fine grained per property /chosen updating.
Implement a suggestion by Scott Wood to make the /chosen handling fine
grained.  Don't overwrite pre-existing properties on a per-property basis,
so if /chosen exists but a necessary /chosen/property doesn't, it gets
created.  If a /chosen property exists, it is NOT overwritten unless the
"force" flag is true.

9eb77cea1f Add additional fdt fixup helper functions
Added the following fdt fixup helpers:
 * do_fixup_by_prop{_u32} - Find matching nodes by property name/value
 * do_fixup_by_compat{_u32} - Find matching nodes by compat

The _u32 variants work the same only the property they are setting
is know to be a 32-bit integer instead of a byte buffer.

a3c2933e02 Removed some nonused fdt functions and moved fdt_find_and_setprop out of libfdt
Removed:
	fdt_node_is_compatible
	fdt_find_node_by_type
	fdt_find_compatible_node

To ease merge of newer libfdt as we aren't using them anywhere at this time.

Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same
reason.

fd61e55dd8 Create new fdt boardsetup command, fix bug parsing [] form of set values.
Previously ft_board_setup() was called by fdt_chosen() which was not
really correctly structured.  This splits ft_board_setup() out by creating
a new fdt boardsetup command.

Fix a bug when parsing fdt set command values which have the square
bracket form [00 11 22 33] - the length was updated incorrectly in when
parsing that form.
