board: raspberrypi: rpi: Add tizen_rpi.env file for Tizen

Add tizen_rpi.env file for using tizen specific environment.
It will be replaced the rpi.env with CONFIG_ENV_SOURCE_FILE.

+ * Memory layout for where various images get loaded by boot scripts:
+ *
+ * I suspect address 0 is used as the SMP pen on the RPi2, so avoid this.
+ *
+ * Older versions of the boot firmware place the firmware-loaded DTB at 0x100,
+ * newer versions place it in high memory. So prevent U-Boot from doing its own
+ * DTB + initrd relocation so that we won't accidentally relocate the initrd
+ * over the firmware-loaded DTB and generally try to lay out things starting
+ * from the bottom of RAM.
+ *
+ * kernel_addr_r has different constraints on ARM and Aarch64.  For 32-bit ARM,
+ * it must be within the first 128M of RAM in order for the kernel's
+ * CONFIG_AUTO_ZRELADDR option to work. The kernel itself will be decompressed
+ * to 0x8000 but the decompressor clobbers 0x4000-0x8000 as well. The
+ * decompressor also likes to relocate itself to right past the end of the
+ * decompressed kernel, so in total the sum of the compressed and
+ * decompressed kernel needs to be reserved.
+ *
+ *   For Aarch64, the kernel image is uncompressed and must be loaded at
+ *   text_offset bytes (specified in the header of the Image) into a 2MB
+ *   boundary. The 'booti' command relocates the image if necessary. Linux uses
+ *   a default text_offset of 0x80000.  In summary, loading at 0x80000
+ *   satisfies all these constraints and reserving memory up to 0x02400000
+ *   permits fairly large (roughly 36M) kernels.
+ *
+ * scriptaddr and pxefile_addr_r can be pretty much anywhere that doesn't
+ * conflict with something else. Reserving 1M for each of them at
+ * 0x02400000-0x02500000 and 0x02500000-0x02600000 should be plenty.
+ *
+ * On ARM, both the DTB and any possible initrd must be loaded such that they
+ * fit inside the lowmem mapping in Linux. In practice, this usually means not
+ * more than ~700M away from the start of the kernel image but this number can
+ * be larger OR smaller depending on e.g. the 'vmalloc=xxxM' command line
+ * parameter given to the kernel. So reserving memory from low to high
+ * satisfies this constraint again. Reserving 1M at 0x02600000-0x02700000 for
+ * the DTB leaves rest of the free RAM to the initrd starting at 0x02700000.
+ * Even with the smallest possible CPU-GPU memory split of the CPU getting
+ * only 64M, the remaining 25M starting at 0x02700000 should allow quite
+ * large initrds before they start colliding with U-Boot.
