Georges Savoundararadj 2e07c249a6 kconfig: arm: introduce symbol for ARM CPUs
This commit introduces a Kconfig symbol for each ARM CPU:
CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136,
CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

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.
