9ae55ccf60 Blackfin: enable -O2 in lib_generic/ for ADI/Bluetechnix boards
Building the compression code in lib_generic/ with -O2 rather than -Os
gives a nice speed boost without too much code size increase.

9ff67e5e4c Blackfin: unify u-boot linker scripts
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.

02778f2f1b Blackfin: fix booting with older bootroms (no EVT1)
When dropping jump block support, the assumption was that all bootroms
supported entry point redirection via the EVT1 register.  Unfortunately,
this turned out to be incorrect for the oldest Blackfin parts (BF533-0.2
and older and BF561).  No one really noticed earlier because these parts
usually are booted by bypassing the bootrom entirely, and older BF533
parts are not supported at all (too many anomalies).

7e1d212b6d Blackfin: kill off LDR jump block
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.

41f3325ae9 Blackfin: drop dead/wrong debug code in initdram()
The DEBUG code in initdram() is quite old and was never really useful, so
just drop it altogether.  Common Blackfin debug code does a better job.

e7e684b10d Blackfin: fix out-of-tree building with ldscripts
Many of the Blackfin board linker scripts are preprocessed, so make sure we
output the linker script into the build tree rather than the source tree.

b9eecc342f Blackfin: fix linker scripts to work with --gc-sections
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.

In order to boot an LDR out of parallel flash, the ldr utility needs a few
flags to tell it to generate the right header.

c23bff63fb Blackfin: linker scripts: force start.o and set initcode boundaries
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.

9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

9171fc8172 Blackfin: unify cpu and boot modes
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).
