autoconfig.mk: Make it possible to define configs from other configs
Give more flexibility to define configs that can be interpreted by make, e.g. to
define fallback values of configs like in the example below.
Before this change, the config lines:
#define CONFIG_SPL_MAX_SIZE 2048
#define CONFIG_SPL_PAD_TO CONFIG_SPL_MAX_SIZE
would have been changed in autoconfig.mk into:
CONFIG_SPL_MAX_SIZE=2048
CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE"
Hence, a make recipe using as an argument to $(OBJCOPY):
--pad-to=$(CONFIG_SPL_PAD_TO)
would have issued:
--pad-to="CONFIG_SPL_MAX_SIZE"
which means nothing for $(OBJCOPY) and makes it fail.
Thanks to this change, the config lines above are changed in autoconfig.mk into:
CONFIG_SPL_MAX_SIZE=2048
CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE)
Hence, the make recipe above now issues:
--pad-to=2048
as expected from the defined config.

arm: relocate_code(): Use __image_copy_end for end of relocation
Use __image_copy_end instead of __bss_start for the end of the image to
relocate. This is the same as commit 033ca72, but applied to all ARM start.S.
This is a more appropriate symbol naming for an image copy & relocate feature,
and this also saves a useless copy of data put between __image_copy_end and
__bss_start in linker scripts (e.g. relocation information, or MMU
initialization tables used only before jumping to the relocated image).
Currently is_16bit_nand() is a per SoC function and it decides the bus nand
width by reading some boot related registers.
This method works when NAND is the boot medium, but does not work if another
boot medium is used. For example: booting from a SD card and then using NAND
to store the environment variables, would lead to the following error:
NAND bus width 16 instead 8 bit
No NAND device found!!!
0 MiB
Use CONFIG_SYS_NAND_BUSWIDTH_16BIT symbol to decide the bus width.
If it is defined in the board file, then consider 16-bit NAND bus-width,
otherwise assume 8-bit NAND is used.
This also aligns with Documentation/devicetree/bindings/mtd/nand.txt, which
states:
nand-bus-width : 8 or 16 bus width if not present 8

do_sdram_init() because of which dmm_init() uses uninitialized
