Masahiro Yamada dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

U-Boot for SolidRun Hummingboard
--------------------------------

This file contains information for the port of U-Boot to the Hummingboard.

For more details about Hummingboard, please refer to:
http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware

(Carrier-One was the previous name of Hummingboard).

Building U-boot for Hummingboard
--------------------------------

To build U-Boot for the Hummingboard Solo version:

$ make hummingboard_solo_config
$ make

Flashing U-boot into the SD card
--------------------------------

- After the 'make' command completes, the generated 'u-boot.imx' binary must be
flashed into the SD card:

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

(Note - the SD card node may vary, so adjust this as needed).

Also, a more detailed explanation on how to format the SD card is available
at doc/README.imximage.

- Insert the micro SD card into the slot located in the bottom of the board

- Connect a 3.3V USB to serial converter cable to the host PC. The MX6 UART
signals are available in the 26 pin connector as shown at:
http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware
(Check for "26 pin header layout").

- Power up the board via USB cable (CON201) and U-boot messages will appear in
the serial console.
