+Subject: [PATCH] rpi: passthrough of the firmware provided FDT blob
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Raspberry firmware used to pass a FDT blob at a fixed address (0x100),
+but this is not true anymore. The address now depends on both the
+memory size and the blob size [1].
+
+If one wants to passthrough this FDT blob to the kernel, the most
+reliable way is to save its address from the r2/x0 register in the
+U-Boot entry point and expose it in a environment variable for
+further processing.
+
+This patch just does this:
+- save the provided address in the global variable fw_dtb_pointer
+- expose it in ${fdt_addr} if it points to a a valid FDT blob
+
+There are many different ways to use it. One can, for example, use
+the following script which will extract from the tree the command
+line built by the firmware, then hand over the blob to a previously
+loaded kernel:
+
+fdt addr ${fdt_addr}
+fdt get value bootargs /chosen bootargs
+bootz ${kernel_addr_r} - ${fdt_addr}
+
+Alternatively, users relying on sysboot/pxe can simply omit any FDT
+statement in their extlinux.conf file, U-Boot will automagically pick
+${fdt_addr} and pass it to the kernel.
