U-Boot for UniPhier SoC family
==============================


Tested toolchains
-----------------

 (a) Ubuntu packages  (CROSS_COMPILE=arm-linux-gnueabi-)

  If you are building U-Boot on Ubuntu, its standard package is recommended.
  You can install it as follows:

    $ sudo apt-get install gcc-arm-linux-gnueabi-

 (b) Linaro compilers  (CROSS_COMPILE=arm-linux-gnueabihf-)

  You can download pre-built toolchains from:

    http://www.linaro.org/downloads/

 (c) kernel.org compilers  (CROSS_COMPILE=arm-unknown-linux-gnueabi-)

  You can download pre-built toolchains from:

    ftp://www.kernel.org/pub/tools/crosstool/files/bin/


Compile the source
------------------

PH1-sLD3 reference board:
    $ make uniphier_sld3_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi-

PH1-LD4 reference board:
    $ make uniphier_ld4_sld8_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi-

PH1-sLD8 reference board:
    $ make uniphier_ld4_sld8_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-ph1-sld8-ref

PH1-Pro4 reference board:
    $ make uniphier_pro4_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi-

PH1-Pro5 4KBOX Board:
    $ make uniphier_pro5_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi-

ProXstream2 Gentil board:
    $ make uniphier_pxs2_ld6b_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-proxstream2-gentil

ProXstream2 Vodka board:
    $ make uniphier_pxs2_ld6b_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi-

PH1-LD6b reference board:
    $ make uniphier_pxs2_ld6b_defconfig
    $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-ph1-ld6b-ref

You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
to use your favorite compiler.


Burn U-Boot images to NAND
--------------------------

Write two files to the NAND device as follows:
 - spl/u-boot-spl.bin at the offset address 0x00000000
 - u-boot.img         at the offset address 0x00010000

If a TFTP server is available, the images can be easily updated.
Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
directory, and then run the following command at the U-Boot command line:

  => run nandupdate


Burn U-Boot images to eMMC
--------------------------

Write two files to the Boot partition 1 of the eMMC device as follows:
 - spl/u-boot-spl.bin at the offset address 0x00000000
 - u-boot.img         at the offset address 0x00010000

If a TFTP server is available, the images can be easily updated.
Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
directory, and then run the following command at the U-Boot command line:

  => run emmcupdate


UniPhier specific commands
--------------------------

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

 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
     shows the DDR PHY parameters set by the PHY training


Supported devices
-----------------

 - UART (on-chip)
 - NAND
 - SD/eMMC
 - USB 2.0 (EHCI)
 - USB 3.0 (xHCI)
 - GPIO
 - LAN (on-board SMSC9118)
 - I2C
 - EEPROM (connected to the on-board I2C bus)
 - Support card (SRAM, NOR flash, some peripherals)


Micro Support Card
------------------

The recommended bit switch settings are as follows:

 SW2    OFF(1)/ON(0)   Description
 ------------------------------------------
 bit 1   <----         BKSZ[0]
 bit 2   ---->         BKSZ[1]
 bit 3   <----         SoC Bus Width 16/32
 bit 4   <----         SERIAL_SEL[0]
 bit 5   ---->         SERIAL_SEL[1]
 bit 6   ---->         BOOTSWAP_EN
 bit 7   <----         CS1/CS5
 bit 8   <----         SOC_SERIAL_DISABLE

 SW8    OFF(1)/ON(0)   Description
 ------------------------------------------
 bit 1    <----        CS1_SPLIT
 bit 2    <----        CASE9_ON
 bit 3    <----        CASE10_ON
 bit 4  Don't Care     Reserve
 bit 5  Don't Care     Reserve
 bit 6  Don't Care     Reserve
 bit 7    ---->        BURST_EN
 bit 8    ---->        FLASHBUS32_16

The BKSZ[1:0] specifies the address range of memory slot and peripherals
as follows:

 BKSZ    Description              RAM slot            Peripherals
 --------------------------------------------------------------------
 0b00   15MB RAM / 1MB Peri    00000000-00efffff    00f00000-00ffffff
 0b01   31MB RAM / 1MB Peri    00000000-01efffff    01f00000-01ffffff
 0b10   64MB RAM / 1MB Peri    00000000-03efffff    03f00000-03ffffff
 0b11  127MB RAM / 1MB Peri    00000000-07efffff    07f00000-07ffffff

Set BSKZ[1:0] to 0b01 for U-Boot.
This mode is the most handy because EA[24] is always supported by the save pin
mode of the system bus.  On the other hand, EA[25] is not supported for some
newer SoCs.  Even if it is, EA[25] is not connected on most of the boards.
