Some parts lack Bank B in L1 data, so have the linker script fall back to
Bank A when that happens. This way we can still leverage L1 data.

The Blackfin on-chip BootROM requires that fill operations (which is
used for the bss) be aligned to 4 bytes (base addr and total len).
Plus, the Blackfin early init asm code assumes the same thing. So
rather than making things work for no real gain, make sure the bss
len is padded to 4 bytes in the linker script.

Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk
This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.

Now that the linker script is preprocessed with -ansi, there is no need to
manually undef the bfin define.

The strictest alignment on Blackfin systems is 32bits (since that is the
largest load instruction), so don't force 256byte alignment here.

The length of the sections is fixed at link time, so let the linker do the
calculation rather than doing it ourselves at runtime.

Sadly, the Blackfin linker script unification lost a small #ifdef logic
needed on older parts. Restore that CONFIG_BFIN_BOOTROM_USES_EVT1 logic.

All the Blackfin linker scripts were duplicated across the board dirs with
no difference save from the semi-often used ENV_IS_EMBEDDED option. So
unify all of them in the lib_blackfin/ dir and for the few boards that
need to embedded the environment directly, add a LDS_BOARD_TEXT define for
them to customize via their board config file. This is much simpler than
forcing them to duplicate the rest of the linker script.

The Boot ROM uses EVT1 as the entry point so set that rather than having
to use a tiny jump block in the default EVT1 location.

Make sure all .text sections get pulled in and the entry point is properly
referenced so they don't get discarded when linking with --gc-sections.

Make sure that the start.o object is always the first object in our linker
script regardless of configuration settings, and add some linker symbols
so the ldr utility can properly locate the initcode when generating a LDR.

All of the duplicated code for Blackfin processors and boot modes have been
unified. After all, the core is the same for all processors, just the
peripheral set differs (which gets handled in the drivers).
