Hello,
this is like not part of this patch at all but is quite related.
There is a question that bugs me for a while.
I wanted to flash u-boot to an onboard memory (like a SPI NOR flash)
alongside a devicetree for the device so I can load just bare zImage
from anywhere the user points to and pass it the device tree from the
flash.
I could probably modify the environment to just read the devicetree
from the flash and be done with it for bare zImage.
But how do you do this when chainloading grub?
1) Ensure the previous bootloader passes the DTB pointer in a register.
2) Apply a patch to U-Boot to pick up that value, save it, and export it
to $dtb_addr, e.g.:
http://patchwork.ozlabs.org/patch/693632/
rpi: passthrough of the firmware provided FDT blob
?
