3b8ac464f2 FPGA: add support for downloading Lattice bitstream
The patch adds support to load a Lattice's bitstream
image (called VME file) into a Lattice FPGA. The code
containing the state machine delivered as part of
Lattice's ispVMtools is integrated.

The FPGA is programmed using the JTAG interface. The
board maintainer must provide accessors to drive the
JTAG signals TCK, TMS, TDI and to get the value of the
input signal TDO.

89083346d0 add block write function to spartan3 slave serial load
Using seperate function calls for each bit-bang of slave serial
load can be painfully slow. This patch adds the possibility to
supply a block write function that loads the complete block of
data in one call (like it can already be done with Altera FPGAs).
On an MCF5373L (240 MHz) loading an XC3S4000 this reduces the load
time from around 15 seconds to around 3 seconds

6385b28116 fpga: Remove relocation fixups
PPC boards are the only users of the current FPGA code which is littered
with manual relocation fixups.  Now that proper relocation is supported
for PPC boards, remove FPGA manual relocation.

670cbde8da fpga: Fix Spartan III FPGA booting
This patch does some minor fixing of the Xilinx Spartan III
FPGA boot code:

- Fixed call order of post configuration callback and
  success message printing (result of copy-paste?)
- remove obsolete comment
- minor coding style cleanup

3818b67764 fpga: Fix Spartan II FPGA booting
This patch does some minor fixing of the Xilinx Spartan II
FPGA boot code:

- Fixed call order of post configuration callback and
  success message printing (result of copy-paste?)
- relocate post configuration callback only when it
  is implemented
- remove obsolete comment
- minor coding style cleanup
