cros_bundle_firmware: Support a read-only EC binary property
We currently support the read-write EC binary. Add support for the read-only
binary as well so we can put this into the firmware image and update it.
Rename the existing 'ecbin' property to 'ecrw' since it is actually only the
read-write portion.
BUG=chrome-os-partner:12806
TEST=manual
Manually modify the device tree source file in U-Boot to request ecro, and
rebuild U-Boot
ro-boot {
label = "u-boot";
size = <0x9a000>;
read-only;
type = "blob boot,dtb,ecrw,ecro";
required;
};
$ cros_bundle_firmware -b daisy -d exynos5250-snow -O out
See that the ecro region now appears in the image:
$ fdtdump out/updated.dtb
...
ecrw {
reg = <0x0006e894 0x0000a370>;
};
boot {
reg = <0x00000000 0x000698d0>;
};
dtb {
reg = <0x000698d0 0x00004fc3>;
};
ecro {
reg = <0x00078c04 0x0000a500>;
};
