CONFIG_SYS_FSL_DSP_CCSRBAR_DEFAULT
This value denotes start offset of DSP CCSR space.
+ CONFIG_SYS_FSL_SINGLE_SOURCE_CLK
+ Single Source Clock is clocking mode present in some of FSL SoC's.
+ In this mode, a single differential clock is used to supply
+ clocks to the sysclock, ddrclock and usbclock.
+
- Generic CPU options:
CONFIG_SYS_BIG_ENDIAN, CONFIG_SYS_LITTLE_ENDIAN
Defines the size and behavior of the NAND that SPL uses
to read U-Boot
+ CONFIG_SPL_NAND_BOOT
+ Add support NAND boot
+
CONFIG_SYS_NAND_U_BOOT_OFFS
Location in NAND to read U-Boot from
Load Address: 0x00000000
Entry Point: 0x00000000
+The "dumpimage" is a tool to disassemble images built by mkimage. Its "-i"
+option performs the converse operation of the mkimage's second form (the "-d"
+option). Given an image built by mkimage, the dumpimage extracts a "data file"
+from the image:
+
+ tools/dumpimage -i image -p position data_file
+ -i ==> extract from the 'image' a specific 'data_file', \
+ indexed by 'position'

+========================================
+Renesas SH7753 EVB board
+========================================
+
+This board specification:
+=========================
+
+The SH7753 EVB (board config name:sh7753evb) has the following device:
+
+ - SH7753 (SH-4A)
+ - DDR3-SDRAM 512MB
+ - SPI ROM 8MB
+ - Gigabit Ethernet controllers
+ - eMMC 4GB
+
+
+Configuration for This board:
+=============================
+
+You can select the configuration as follows:
+
+ - make sh7753evb_config
+
+
+This board specific command:
+============================
+
+This board has the following its specific command:
+
+ - write_mac
+
+
+1. write_mac
+
+You can write MAC address to SPI ROM.
+
+ Usage 1) Write MAC address
+
+ write_mac [GETHERC ch0] [GETHERC ch1]
+
+ For example)
+ => write_mac 74:90:50:00:33:9e 74:90:50:00:33:9f
+ *) We have to input the command as a single line
+ (without carriage return)
+ *) We have to reset after input the command.
+
+ Usage 2) Show current data
+
+ write_mac
+
+ For example)
+ => write_mac
+ GETHERC ch0 = 74:90:50:00:33:9e
+ GETHERC ch1 = 74:90:50:00:33:9f
+
+
+Update SPI ROM:
+============================
+
+1. Copy u-boot image to RAM area.
+2. Probe SPI device.
+ => sf probe 0
+ SF: Detected MX25L6405D with page size 64KiB, total 8 MiB
+3. Erase SPI ROM.
+ => sf erase 0 80000
+4. Write u-boot image to SPI ROM.
+ => sf write 0x48000000 0 80000

+SOCFPGA Documentation for U-Boot and SPL
+--------------------------------------------

+based SOCFPGA. To know more about the hardware itself, please refer to
+www.altera.com.

+--------------------------------------------
+Here are macro and detailed configuration required to enable DesignWare SDMMC
+controller support within SOCFPGA
+
+#define CONFIG_MMC
+-> To enable the SD MMC framework support
+
+#define CONFIG_SDMMC_BASE (SOCFPGA_SDMMC_ADDRESS)
+-> The base address of CSR register for DesignWare SDMMC controller
+
+#define CONFIG_GENERIC_MMC
+-> Enable the generic MMC driver
+
+#define CONFIG_SYS_MMC_MAX_BLK_COUNT 256
+-> Using smaller max blk cnt to avoid flooding the limited stack in OCRAM
+
+#define CONFIG_DWMMC
+-> Enable the common DesignWare SDMMC controller framework
+
+#define CONFIG_SOCFPGA_DWMMC
+-> Enable the SOCFPGA specific driver for DesignWare SDMMC controller
+
+#define CONFIG_SOCFPGA_DWMMC_FIFO_DEPTH 1024
+-> The FIFO depth for SOCFPGA DesignWare SDMMC controller
+
+#define CONFIG_SOCFPGA_DWMMC_DRVSEL 3
+-> Phase-shifted clock of sdmmc_clk for controller to drive command and data to
+the card to meet hold time requirements. SD clock is running at 50MHz and
+drvsel is set to shift 135 degrees (3 * 45 degrees). With that, the hold time
+is 135 / 360 * 20ns = 7.5ns.
+
+#define CONFIG_SOCFPGA_DWMMC_SMPSEL 0
+-> Phase-shifted clock of sdmmc_clk used to sample the command and data from
+the card
+
+#define CONFIG_SOCFPGA_DWMMC_BUS_WIDTH 4
+-> Bus width of data line which either 1, 4 or 8 and based on board routing.
+
+#define CONFIG_SOCFPGA_DWMMC_BUS_HZ 50000000
+-> The clock rate to controller. Do note the controller have a wrapper which
+divide the clock from PLL by 4.

+From VxWorks 6.9+ (not include 6.9), VxWorks starts adopting device tree as its hardware
+decription mechansim (for PowerPC and ARM), thus requiring boot interface changes.
+This section will describe the new interface.
+
+For PowerPC, the calling convention of the new VxWorks entry point conforms to the ePAPR standard,
+which is shown below (see ePAPR for more details):
+
+ void (*kernel_entry)(fdt_addr,
+ 0, 0, EPAPR_MAGIC, boot_IMA, 0, 0)
+
+For ARM, the calling convention is show below:
+
+ void (*kernel_entry)(void *fdt_addr)
+
+When booting new VxWorks kernel (uImage format), the parameters passed to bootm is like below:
+
+ bootm <kernel image address> - <device tree address>
+
+The do_bootvx command still works as it was for older VxWorks kernels.
