+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.

+SPI/QSPI Dual flash connection modes:
+=====================================
+
+This describes how SPI/QSPI flash memories are connected to a given
+controller in a single chip select line.
+
+Current spi_flash framework supports, single flash memory connected
+to a given controller with single chip select line, but there are some
+hw logics(ex: xilinx zynq qspi) that describes two/dual memories are
+connected with a single chip select line from a controller.
+
+"dual_flash" from include/spi.h describes these types of connection mode
+
+Possible connections:
+--------------------
+SF_SINGLE_FLASH:
+ - single spi flash memory connected with single chip select line.
+
+ +------------+ CS +---------------+
+ | |----------------------->| |
+ | Controller | I0[3:0] | Flash memory |
+ | SPI/QSPI |<======================>| (SPI/QSPI) |
+ | | CLK | |
+ | |----------------------->| |
+ +------------+ +---------------+
+
+SF_DUAL_STACKED_FLASH:
+ - dual spi/qspi flash memories are connected with a single chipselect
+ line and these two memories are operating stacked fasion with shared buses.
+ - xilinx zynq qspi controller has implemented this feature [1]
+
+ +------------+ CS +---------------+
+ | |---------------------->| |
+ | | I0[3:0] | Upper Flash |
+ | | +=========>| memory |
+ | | | CLK | (SPI/QSPI) |
+ | | | +---->| |
+ | Controller | CS | | +---------------+
+ | SPI/QSPI |------------|----|---->| |
+ | | I0[3:0] | | | Lower Flash |
+ | |<===========+====|====>| memory |
+ | | CLK | | (SPI/QSPI) |
+ | |-----------------+---->| |
+ +------------+ +---------------+
+
+ - two memory flash devices should has same hw part attributes (like size,
+ vendor..etc)
+ - Configurations:
+ on LQSPI_CFG register, Enable TWO_MEM[BIT:30] on LQSPI_CFG
+ Enable U_PAGE[BIT:28] if U_PAGE flag set - upper memory
+ Disable U_PAGE[BIT:28] if U_PAGE flag unset - lower memory
+ - Operation:
+ accessing memories serially like one after another.
+ by default, if U_PAGE is unset lower memory should accessible,
+ once user wants to access upper memory need to set U_PAGE.
+
+SPI_FLASH_CONN_DUALPARALLEL:
+ - dual spi/qspi flash memories are connected with a single chipselect
+ line and these two memories are operating parallel with separate buses.
+ - xilinx zynq qspi controller has implemented this feature [1]
+
+ +-------------+ CS +---------------+
+ | |---------------------->| |
+ | | I0[3:0] | Upper Flash |
+ | |<=====================>| memory |
+ | | CLK | (SPI/QSPI) |
+ | |---------------------->| |
+ | Controller | CS +---------------+
+ | SPI/QSPI |---------------------->| |
+ | | I0[3:0] | Lower Flash |
+ | |<=====================>| memory |
+ | | CLK | (SPI/QSPI) |
+ | |---------------------->| |
+ +-------------+ +---------------+
+
+ - two memory flash devices should has same hw part attributes (like size,
+ vendor..etc)
+ - Configurations:
+ Need to enable SEP_BUS[BIT:29],TWO_MEM[BIT:30] on LQSPI_CFG register.
+ - Operation:
+ Even bits, i.e. bit 0, 2, 4 ., of a data word is located in the lower memory
+ and odd bits, i.e. bit 1, 3, 5, ., of a data word is located in the upper memory.
+
+Note: Technically there is only one CS line from the controller, but
+zynq qspi controller has an internal hw logic to enable additional CS
+when controller is configured for dual memories.
