5Tested toolchains
6-----------------
7
8 (a) Ubuntu packages  (CROSS_COMPILE=arm-linux-gnueabi-)
9
10  If you are building U-Boot on Ubuntu, its standard package is recommended.
11  You can install it as follows:
12
13    $ sudo apt-get install gcc-arm-linux-gnueabi-
14
15 (b) Linaro compilers  (CROSS_COMPILE=arm-linux-gnueabihf-)
16
17  You can download pre-built toolchains from:
18
19    http://www.linaro.org/downloads/
20
21 (c) kernel.org compilers  (CROSS_COMPILE=arm-unknown-linux-gnueabi-)
22
23  You can download pre-built toolchains from:

28Compile the source
29------------------
30
31PH1-Pro4:
32    $ make ph1_pro4_defconfig
33    $ make CROSS_COMPILE=arm-linux-gnueabi-
34
35PH1-LD4:
36    $ make ph1_ld4_defconfig
37    $ make CROSS_COMPILE=arm-linux-gnueabi-
38
39PH1-sLD8:
40    $ make ph1_sld8_defconfig
41    $ make CROSS_COMPILE=arm-linux-gnueabi-
42
43You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
44to use your favorite compiler.

47Burn U-Boot images to NAND
48--------------------------
49
50Write two files to the NAND device as follows:
51 - spl/u-boot-spl.bin at the offset address 0x00000000
52 - u-boot-dtb.img     at the offset address 0x00010000
53
54If a TFTP server is available, the images can be easily updated.
55Just copy the u-boot-spl.bin and u-boot-dtb.img to the TFTP public directory,
56and then run the following command at the U-Boot command line:
57
58  => run nandupdate
59
60
61UniPhier specific commands
62--------------------------
63
64 - pinmon (enabled by CONFIG_CMD_PINMON)
65     shows the boot mode pins that has been latched at the power-on reset
66
67 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
68     shows the DDR PHY parameters set by the PHY training
69
70
71Supported devices
72-----------------
73
74 - UART (on-chip)
75 - NAND
76 - USB 2.0 (EHCI)
77 - USB 3.0 (xHCI)
78 - LAN (on-board SMSC9118)
79 - I2C
80 - EEPROM (connected to the on-board I2C bus)
81 - Support card (SRAM, NOR flash, some peripherals)
