This patch adds artec dbe61 support, removes all mainboard.c, and
adds
the code to dtc so that it takes these properties from the top level
dts:
/{
.
.
.
mainboard-vendor = "AMD";
mainboard-part-number = "Norwich";
}
statictree.h will have:
extern const char *mainboard_vendor, *mainboard_part_number;
and statictree.c will have:
const char *mainboard_vendor = "AMD";
const char *mainboard_part_number = "Norwich";
It is an error to NOT have the vendor and part number in the top
level dts.
thanks
ron
Get rid of mainboard.c in all mainboard directories.
Modify dtc so that it creates declarations (in statictree.h) and
generates the char *
for mainboard name and part # (in statictree.c).
Failure to set up a mainboard-vendor
OR mainboard-part-number property in the mainboard dts will get a
helpful and descriptive error message (tested).
This may be a first for the linuxbios config
tools.
Add Georgi's patch for the bug in flattree.c; assign *cp = 0.
