-Implement a hook to allow boards to save boot-time CPU state for later
-use. When U-Boot is chain-loaded by another bootloader, CPU registers may
-contain useful information such as system configuration information. This
-feature mirrors the equivalent ARMv7 feature.

-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.
