an arbitrary address in RAM.
Adapt the TX25 (i.MX25), magnesium board to test the changes.
On the tx25 board TEXT_BASE is set to the final relocation
address to prevent one more copying of u-boot code
when relocating. More info see:

ARM (ARM926ejs): add data cache support, tested on magnesium and tx25 board
Enable "cache" command on tx25 and magnesium board and test performance.
Test 1: Loading 127 MB of data from NAND flash into RAM:
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
magnesium 32,6s 22,5s 30s = x 1,09
tx25 (29MB only) 9,69s 5,05s 8,16s = x 1,19
Test 2: uncompressing a gzipped image from RAM to RAM
(size compressed: 6.5 MiB, uncompressed: 35 MiB):
Instr. Cache off on on
Data Cache off off on
--------------------------------------------------
magnesium 4,25s 2,08s 1,72s = x 2,47
tx25 4,82s 2,04s 1,84s = x 2,62

arm, i.mx27: add support for magnesium board from projectiondesign
This patch adds support for the magnesium board from
projectiondesign. This board uses i.MX27 SoC and has
8MB NOR flash, 128MB NAND flash, FEC ethernet controller
integrated into i.MX27. As this port is based on
the imx27lite port, common config options are collected
in include/configs/imx27lite-common.h
