  61     $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-ph1-ld6b-ref
  62
  63 You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
  64 to use your favorite compiler.

  66
  67 Burn U-Boot images to NAND
  68 --------------------------
  69
  70 Write two files to the NAND device as follows:
  71  - spl/u-boot-spl.bin at the offset address 0x00000000
  72  - u-boot.img         at the offset address 0x00010000
  73
  74 If a TFTP server is available, the images can be easily updated.
  75 Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
  76 directory, and then run the following command at the U-Boot command line:
  77
  78   => run nandupdate
  79
  80
  81 Burn U-Boot images to eMMC
  82 --------------------------
  83
  84 Write two files to the Boot partition 1 of the eMMC device as follows:
  85  - spl/u-boot-spl.bin at the offset address 0x00000000
  86  - u-boot.img         at the offset address 0x00010000
  87
  88 If a TFTP server is available, the images can be easily updated.
  89 Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
  90 directory, and then run the following command at the U-Boot command line:
  91
  92   => run emmcupdate
  93
  94
  95 UniPhier specific commands

  97
  98  - pinmon (enabled by CONFIG_CMD_PINMON)
  99      shows the boot mode pins that has been latched at the power-on reset
 100

 123 The recommended bit switch settings are as follows:
 124
 125  SW2    OFF(1)/ON(0)   Description
 126  ------------------------------------------
 127  bit 1   <----         BKSZ[0]
 128  bit 2   ---->         BKSZ[1]
 129  bit 3   <----         SoC Bus Width 16/32
 130  bit 4   <----         SERIAL_SEL[0]
 131  bit 5   ---->         SERIAL_SEL[1]
 132  bit 6   ---->         BOOTSWAP_EN
 133  bit 7   <----         CS1/CS5
 134  bit 8   <----         SOC_SERIAL_DISABLE
 135
 136  SW8    OFF(1)/ON(0)   Description
 137  ------------------------------------------
 138  bit 1    <----        CS1_SPLIT
 139  bit 2    <----        CASE9_ON
 140  bit 3    <----        CASE10_ON
 141  bit 4  Don't Care     Reserve
 142  bit 5  Don't Care     Reserve
 143  bit 6  Don't Care     Reserve
 144  bit 7    ---->        BURST_EN
 145  bit 8    ---->        FLASHBUS32_16
 146
 147 The BKSZ[1:0] specifies the address range of memory slot and peripherals
 148 as follows:
 149
 150  BKSZ    Description              RAM slot            Peripherals
 151  --------------------------------------------------------------------
 152  0b00   15MB RAM / 1MB Peri    00000000-00efffff    00f00000-00ffffff
 153  0b01   31MB RAM / 1MB Peri    00000000-01efffff    01f00000-01ffffff
 154  0b10   64MB RAM / 1MB Peri    00000000-03efffff    03f00000-03ffffff
 155  0b11  127MB RAM / 1MB Peri    00000000-07efffff    07f00000-07ffffff
 156
 157 Set BSKZ[1:0] to 0b01 for U-Boot.
 158 This mode is the most handy because EA[24] is always supported by the save pin
 159 mode of the system bus.  On the other hand, EA[25] is not supported for some
 160 newer SoCs.  Even if it is, EA[25] is not connected on most of the boards.
