Stefano Babic 552a848e4f imx: reorganize IMX code as other SOCs 
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

U-Boot for the Congatec QMX6 boards

This file contains information for the port of U-Boot to the Congatec
QMX6 boards.

1. Building U-Boot
------------------

- Build U-Boot for Congatec QMX6 boards:

$ make mrproper
$ make cgtqmx6eval_defconfig
$ make

This will generate the following binaries:

- SPL
- u-boot.img

2. Flashing U-Boot in the SPI NOR
---------------------------------

Copy SPL and u-boot.img to the exported TFTP directory of the
host PC (/tftpboot , for example).

=> sf probe

=> setenv serverip <server_ip_address>

=> setenv ipaddr <board_ip_address>

=> tftp 0x12000000 SPL

=> sf erase 0x0 0x10000

=> sf write 0x12000000 0x400 0x10000

=> tftp 0x12000000 u-boot.img

=> sf erase 0x10000 0x70000

=> sf write 0x12000000 0x10000 0x70000

Reboot the board and the new U-Boot should come up.

3. Booting from the SD card
---------------------------

- Flash the SPL image into the SD card:

sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

- Flash the u-boot.img image into the SD card:

sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Insert the SD card into the big slot.

The boot medium of Congatec QMX6 boards is the SPI NOR flash, so boot
the board from SPI first.

It is also possible to boot from the SD card slot by using the 'bmode'
command:

=> bmode esdhc4

And then the U-Boot from the big slot will boot.

Note: If the "bmode" command is not available from your pre-installed U-Boot,
these instruction will produce the same effect:

=> mw.l 0x20d8040 0x3850
=> mw.l 0x020d8044 0x10000000
=> reset
