fdt: avoid bad MAKEALL status

2012-04-21T14:48:14+00:00

Current versions of  dtc  always print a message like

	DTC: dts->dtb  on file "dt.dtb.tmp"

which cannot even be suppressed with "-qqq".  To avoid incorrect
MAKEALL status, we manually filter out this message.  This is a bit
complicated, as we have to make sure to set a correct return code.

Also, get rid of the temp file: dtc accepts "-" for stdin.

fdt: Add support for embedded device tree (CONFIG_OF_EMBED)

2011-10-26T19:38:59+00:00

This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's
own use and is not necessarily the same one as is passed to the kernel.

The device tree compiler output should be placed in the $(obj)
rooted tree. Since $(OBJCOPY) insists on adding the path to the
generated symbol names, to ensure consistency it should be
invoked from the directory where the .dtb file is located and
given the input file name without the path.

This commit contains my entry for the ugliest Makefile / shell interaction
competition.
