doc: cleanup - move board READMEs into respective board directories
Also drop a few files referring to no longer / not yet supported
boards.

Boot source, boot from SD card +--------------------------------- + +The recent mainline U-Boot for the Freescale i.MX6q SabreLite board supports +boot from SD card only. However, by default, the SabreLite +boards boot from the SPI NOR flash. These boards need to be reflashed with +a small SD card loader to support boot from SD card. This small SD card loader +will be flashed into the SPI NOR. The board will still boot from SPI NOR, but +the loader will in turn request the BootROM to load the U-Boot from SD card. + +The SD card loader is available from + +https://wiki.linaro.org/Boards/MX6QSabreLite + +under a open-source 3-clause BSD license. + +To update the SPI-NOR on the SabreLite board without the Freescale +manufacturing tool use the following procedure: + +1. Write this SD card loader onto a large SD card using: + + sudo dd if=iMX6DQ_SPI_to_uSDHC3.bin of=/dev/sXx + +Note: Replace sXx with the device representing the SD card in your system. + +Note: This writes SD card loader at address 0 + +2. Put this SD card into the slot for the large SD card (SD3 on the bottom of +the board). Make sure SW1 switch is at position "00", so that it can boot +from the fuses. + +3. Power-up the SabreLite, press 'space' to enter command mode in the U-Boot +(the default one the board is shipped with, starting from the SPI NOR) and +enter the following commands: + + MX6Q SABRELITE U-Boot > mmc dev 0 + MX6Q SABRELITE U-Boot > mmc read 0x10800000 0 200 + MX6Q SABRELITE U-Boot > sf probe 1 + MX6Q SABRELITE U-Boot > sf erase 0 0x40000 + MX6Q SABRELITE U-Boot > sf write 0x10800000 0 0x40000 + +4. done. + +In case you somehow do not succeed with this procedure you will have to use +the Freescale manufacturing tool in order to reflash the SPI-NOR. + +Note: The board now boots from full size SD3 on the bottom of the board. NOT + the micro SD4/BOOT slot on the top of the board. I.e. you have to use + full size SD cards. + +This information is taken from + +https://wiki.linaro.org/Boards/MX6QSabreLite + +2.
