[U-Boot] [PATCH v2 2/2] add Eukrea's CPUIMX25

["Eric Bénard" <eric@eukrea.com>]

this board is based on an i.MX25 from Freescale.
It consists of a SOM containing :
- NAND flash (internal or external boot supported and tested)
- mDDR (64MB tested)
- ethernet PHY connected in RMII mode (tested)
and a baseboard containing :
- a serial transceiver on UART1 (tested)
- a SDCard connector on eSDHC1 (tested but disabled until Beno?t's fix
  gets applied)

bootlog :
U-Boot 2012.10-rc1-00003-gdd12be5 (Sep 23 2012 - 13:53:21)

CPU:   Freescale i.MX25 rev1.2 at 399 MHz
Reset cause: POR

DRAM:  64 MiB
NAND:  256 MiB
MMC:
In:    serial
Out:   serial
Err:   serial
Net:   FEC
Hit any key to stop autoboot:  0

Signed-off-by: Eric B?nard <eric@eukrea.com>
---
v2: rebased against 2012.10-rc1, disabled eSDHC until proper fix
    from Beno?t gets applied, updated bootlog.
