Change the implementation for arm926 to relocate the code to
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:

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

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

The support for this was silently dropped by a configuration
split during the merge of the imx27lite board support in commit
864aa034f3 (cmd_mtdparts: Move to common
handling of FLASH devices via MTD layer).

We will get compilation warnings without
"CONFIG_SYS_64BIT_VSPRINTF" being defined
in the board config.

This patch adds support for i.MX27-LITEKIT development board from
LogicPD. This board uses i.MX27 SoC and has 2MB NOR flash, 64MB NAND
flash, FEC ethernet controller integrated into i.MX27.
