   5 Recommended toolchains
   6 ----------------------
   7
   8 The UniPhier platform is well tested with Linaro toolchains.
   9 You can download pre-built toolchains from:
  10
  11     http://www.linaro.org/downloads/
  12
  13
  14 Compile the source
  15 ------------------
  16
  17 The source can be configured and built with the following commands:
  18
  19     $ make <defconfig>
  20     $ make CROSS_COMPILE=<toolchain-prefix> DEVICE_TREE=<device-tree>
  21
  22 The recommended <toolchain-prefix> is `arm-linux-gnueabihf-` for 32bit SoCs,
  23 `aarch64-linux-gnu-` for 64bit SoCs, but you may wish to change it to use your
  24 favorite compiler.
  25
  26 The following tables show <defconfig> and <device-tree> for each board.
  27
  28 32bit SoC boards:
  29
  30  Board         | <defconfig>                  | <device-tree>
  31 ---------------|------------------------------|------------------------------
  32 LD4 reference  | uniphier_ld4_sld8_defconfig  | uniphier-ld4-ref (default)
  33 sld8 reference | uniphier_ld4_sld8_defconfig  | uniphier-sld8-def
  34 Pro4 reference | uniphier_pro4_defconfig      | uniphier-pro4-ref (default)
  35 Pro4 Ace       | uniphier_pro4_defconfig      | uniphier-pro4-ace
  36 Pro4 Sanji     | uniphier_pro4_defconfig      | uniphier-pro4-sanji
  37 Pro5 4KBOX     | uniphier_pxs2_ld6b_defconfig | uniphier-pro5-4kbox
  38 PXs2 Gentil    | uniphier_pxs2_ld6b_defconfig | uniphier-pxs2-gentil
  39 PXs2 Vodka     | uniphier_pxs2_ld6b_defconfig | uniphier-pxs2-vodka (default)
  40 LD6b reference | uniphier_pxs2_ld6b_defconfig | uniphier-ld6b-ref
  41
  42 64bit SoC boards:
  43
  44  Board         | <defconfig>           | <device-tree>
  45 ---------------|-----------------------|----------------------------
  46 LD11 reference | uniphier_v8_defconfig | uniphier-ld11-ref
  47 LD11 Global    | uniphier_v8_defconfig | uniphier-ld11-global
  48 LD20 reference | uniphier_v8_defconfig | uniphier-ld20-ref (default)
  49 LD20 Global    | uniphier_v8_defconfig | uniphier-ld20-global
  50
  51 For example, to compile the source for PXs2 Vodka board, run the following:
  52
  53     $ make uniphier_pxs2_ld6b_defconfig
  54     $ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-pxs2-vodka
  55
  56 The device tree marked as (default) can be omitted.  `uniphier-pxs2-vodka` is
  57 the default device tree for the configuration `uniphier_pxs2_ld6b_defconfig`,
  58 so the following gives the same result.
  59
  60     $ make uniphier_pxs2_ld6b_defconfig
  61     $ make CROSS_COMPILE=arm-linux-gnueabihf-
  62
  63
  64 Booting 32bit SoC boards
  65 ------------------------
  66
  67 The build command will generate the following:
  68 - u-boot.bin
  69 - spl/u-boot.bin
  70
  71 U-Boot can boot UniPhier 32bit SoC boards by itself.  Flash the generated images
  72 to the storage device (NAND or eMMC) on your board.
  73
  74  - spl/u-boot-spl.bin at the offset address 0x00000000
  75  - u-boot.bin         at the offset address 0x00020000
  76
  77 The `u-boot-with-spl.bin` is the concatenation of the two (with appropriate
  78 padding), so you can also do:
  79
  80  - u-boot-with-spl.bin at the offset address 0x00000000
  81
  82 If a TFTP server is available, the images can be easily updated.
  83 Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
  84 and run the following command at the U-Boot command line:
  85
  86 To update the images in NAND:
  87
  88     => run nandupdate
  89
  90 To update the images in eMMC:
  91
  92     => run emmcupdate
  93
  94
  95 Booting 64bit SoC boards
  96 ------------------------
  97
  98 The build command will generate the following:
  99 - u-boot.bin
 100
 101 However, U-Boot is not the first stage loader for UniPhier 64bit SoC boards.
 102 U-Boot serves as a non-secure boot loader loaded by [ARM Trusted Firmware],
 103 so you need to provide the `u-boot.bin` to the build command of ARM Trusted
 104 Firmware.

 141
 142  SW2    OFF(1)/ON(0)   Description
 143  ------------------------------------------
 144  bit 1   <----         BKSZ[0]
 145  bit 2   ---->         BKSZ[1]
 146  bit 3   <----         SoC Bus Width 16/32

 150  bit 7   <----         CS1/CS5
 151  bit 8   <----         SOC_SERIAL_DISABLE
 152
 153  SW8    OFF(1)/ON(0)   Description
 154  ------------------------------------------
 155  bit 1    <----        CS1_SPLIT
 156  bit 2    <----        CASE9_ON
 157  bit 3    <----        CASE10_ON
 158  bit 4  Don't Care     Reserve
 159  bit 5  Don't Care     Reserve
 160  bit 6  Don't Care     Reserve
 161  bit 7    ---->        BURST_EN
 162  bit 8    ---->        FLASHBUS32_16
 163
 164 The BKSZ[1:0] specifies the address range of memory slot and peripherals
 165 as follows:
 166
 167  BKSZ    Description              RAM slot            Peripherals
 168  --------------------------------------------------------------------
 169  0b00   15MB RAM / 1MB Peri    00000000-00efffff    00f00000-00ffffff
 170  0b01   31MB RAM / 1MB Peri    00000000-01efffff    01f00000-01ffffff
 171  0b10   64MB RAM / 1MB Peri    00000000-03efffff    03f00000-03ffffff
 172  0b11  127MB RAM / 1MB Peri    00000000-07efffff    07f00000-07ffffff
 173
 174 Set BSKZ[1:0] to 0b01 for U-Boot.
 175 This mode is the most handy because EA[24] is always supported by the save pin
 176 mode of the system bus.  On the other hand, EA[25] is not supported for some
 177 newer SoCs.  Even if it is, EA[25] is not connected on most of the boards.
