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-)

17  You can download pre-built toolchains from:

63You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
64to use your favorite compiler.

67Burn U-Boot images to NAND
68--------------------------
69
70Write two files to the NAND device as follows:
71 - spl/u-boot-spl-dtb.bin at the offset address 0x00000000
72 - u-boot-dtb.img         at the offset address 0x00010000
73
74If a TFTP server is available, the images can be easily updated.
75Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
76directory, and then run the following command at the U-Boot command line:
77
78  => run nandupdate
79
80
81UniPhier specific commands
82--------------------------
83
84 - pinmon (enabled by CONFIG_CMD_PINMON)
85     shows the boot mode pins that has been latched at the power-on reset
86
87 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
88     shows the DDR PHY parameters set by the PHY training
89
90
91Supported devices
92-----------------
93
94 - UART (on-chip)
95 - NAND
96 - USB 2.0 (EHCI)
97 - USB 3.0 (xHCI)
98 - LAN (on-board SMSC9118)
99 - I2C
100 - EEPROM (connected to the on-board I2C bus)
101 - Support card (SRAM, NOR flash, some peripherals)

107The recommended bit switch settings are as follows:
108
109 SW2    OFF(1)/ON(0)   Description
110 ------------------------------------------
111 bit 1   <----         BKSZ[0]
112 bit 2   ---->         BKSZ[1]
113 bit 3   <----         SoC Bus Width 16/32
114 bit 4   <----         SERIAL_SEL[0]
115 bit 5   ---->         SERIAL_SEL[1]
116 bit 6   ---->         BOOTSWAP_EN
117 bit 7   <----         CS1/CS5
118 bit 8   <----         SOC_SERIAL_DISABLE
119
120 SW8    OFF(1)/ON(0)   Description
121 ------------------------------------------
122 bit 1    <----        CS1_SPLIT
123 bit 2    <----        CASE9_ON
124 bit 3    <----        CASE10_ON
125 bit 4  Don't Care     Reserve
126 bit 5  Don't Care     Reserve
127 bit 6  Don't Care     Reserve
128 bit 7    ---->        BURST_EN
129 bit 8    ---->        FLASHBUS32_16
130
131The BKSZ[1:0] specifies the address range of memory slot and peripherals
132as follows:
133
134 BKSZ    Description              RAM slot            Peripherals
135 --------------------------------------------------------------------
136 0b00   15MB RAM / 1MB Peri    00000000-00efffff    00f00000-00ffffff
137 0b01   31MB RAM / 1MB Peri    00000000-01efffff    01f00000-01ffffff
138 0b10   64MB RAM / 1MB Peri    00000000-03efffff    03f00000-03ffffff
139 0b11  127MB RAM / 1MB Peri    00000000-07efffff    07f00000-07ffffff
140
141Set BSKZ[1:0] to 0b01 for U-Boot.
142This mode is the most handy because EA[24] is always supported by the save pin
143mode of the system bus.  On the other hand, EA[25] is not supported for some
144newer SoCs.  Even if it is, EA[25] is not connected on most of the boards.
