Introduce new mode of relocation which relocates only data, not code. This is mainly meant to relocate data to read-write portion of the RAM, while the code remains in read-only portion of the RAM from which it is allowed to execute. This split configuration is present on various secure cores. The result of the relocation is U-Boot running at its original address, data relocated to the end of DRAM, but with added read-write area offset. The U-Boot binary area is not reserved from the end of the DRAM in this relocation mode, because U-Boot itself is not relocated. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
