Remove linker command line options from the SPL makefile
that force the inclusion of unreferenced command code from
linked object files. As commands are not used in the SPL,
these options resulted in an unnecessary increase in the
image size, in addition to introducing the possibility of
tricky link errors in the case where the command code
contained symbols that were not resolved by linking in the
limited objects compiled in the SPL build.

    mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver

    The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
    silently masks off at least one flag that might be set by the driver
    (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
    others.

    Really, as long as driver writers exercise a small amount of care with
    NAND_* options, this mask is not necessary at all; it was only here to
    prevent certain options from accidentally being set by the driver. But the
    original thought turns out to be a bad idea occasionally. Thus, kill it.

    Note, this patch fixes some major gpmi-nand breakage.

With onfi a flash is organized into one or more logical units (LUNs).
A logical unit (LUN) is the minimum unit that can independently execute
commands and report status.

Mtd does not exploit LUN, so make it see a big single flash where size is
lun_size * number_of_lun.

Without this patch MT29F8G08ADBDAH4 size is 512MiB instead of 1GiB.

In case the "fdt addr" command wasn't ran yet and any other "fdt"
subcommand was issued, the system crashed due to NULL pointer being
used.

This is caused by "fdt addr" command setting up a pointer to the
FDT memory location. Prior issuing "fdt addr", the pointer is NULL
so calling any other subcommands crashed the u-boot.
