[U-Boot] [PATCH v3] mpc83xx: Add NAND boot support for MPC8315E-RDB boards

The core support for NAND booting is there already, so this patch
is pretty straightforward.
There is one trick though: top level Makefile expects nand_spl to
be in nand_spl/board/$(BOARDDIR), but we can fully reuse the code
from mpc8313erdb boards, and so to not duplicate the code we just
symlink nand_spl/board/freescale/mpc8315erdb to mpc8313erdb.

Done.

Fixed, thanks.

Yep, not that easy.

Done.

This is due commit 3eb90bad651fab39cffba750ec4421a9c01d60e7
("Generic udelay() with watchdog support"). SPL code doesn't
use lib_generic/time.c, so nowadays we should use __udelay().
The commit above converted MPC8313ERDB boards, but didn't do the
same for 8315 (there was no need since 8315 didn't use SPL at
that time).
Thanks!

+6. Booting from NAND flash

+6.1 Build U-Boot
+
+ The steps are the same as described in section "4.", but

+ MPC8315ERDB_config.

+ nand erase 0 80000
+ nand write 100000 0 80000
+
+ (The actual U-Boot size might be less than 0x80000, but you

+
+6.3 Сonfigure the board to boot from NAND Flash
+
+ Set S4.4 switch to ON position and S3.4 switch to OFF position.
+
+7 Notes
- Booting from NAND flash is not yet supported.
The console baudrate for MPC8315ERDB is 115200bps.
