1 U-Boot for UniPhier SoC family
2 ==============================
8 The UniPhir platform is well tested with Linaro toolchanis.
9 You can download pre-built toolchains from:

69 You may wish to change the "CROSS_COMPILE=..." to use your favorite compiler.
72 Burn U-Boot images to NAND
73 --------------------------
75 Write the following to the NAND device:
77 - spl/u-boot-spl.bin at the offset address 0x00000000
78 - u-boot.bin at the offset address 0x00020000
82 - u-boot-with-spl.bin at the offset address 0x00000000
84 If a TFTP server is available, the images can be easily updated.
85 Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
86 and then run the following command at the U-Boot command line:
91 Burn U-Boot images to eMMC
92 --------------------------
94 Write the following to the Boot partition 1 of the eMMC device:
96 - spl/u-boot-spl.bin at the offset address 0x00000000
97 - u-boot.bin at the offset address 0x00020000
101 - u-boot-with-spl.bin at the offset address 0x00000000
103 If a TFTP server is available, the images can be easily updated.
104 Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
105 and then run the following command at the U-Boot command line:
110 UniPhier specific commands
111 --------------------------
113 - pinmon (enabled by CONFIG_CMD_PINMON)
114 shows the boot mode pins that has been latched at the power-on reset
116 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
117 shows the DDR PHY parameters set by the PHY training
119 - ddrmphy (enabled by CONFIG_CMD_DDRMPHY_DUMP)
120 shows the DDR Multi PHY parameters set by the PHY training
132 - LAN (on-board SMSC9118)
134 - EEPROM (connected to the on-board I2C bus)
135 - Support card (SRAM, NOR flash, some peripherals)
141 The recommended bit switch settings are as follows:
143 SW2 OFF(1)/ON(0) Description
144 ------------------------------------------
147 bit 3 <---- SoC Bus Width 16/32
148 bit 4 <---- SERIAL_SEL[0]
149 bit 5 ----> SERIAL_SEL[1]
150 bit 6 ----> BOOTSWAP_EN
152 bit 8 <---- SOC_SERIAL_DISABLE
154 SW8 OFF(1)/ON(0) Description
155 ------------------------------------------
156 bit 1 <---- CS1_SPLIT
158 bit 3 <---- CASE10_ON
159 bit 4 Don't Care Reserve
160 bit 5 Don't Care Reserve
161 bit 6 Don't Care Reserve
163 bit 8 ----> FLASHBUS32_16
165 The BKSZ[1:0] specifies the address range of memory slot and peripherals
168 BKSZ Description RAM slot Peripherals
169 --------------------------------------------------------------------
170 0b00 15MB RAM / 1MB Peri 00000000-00efffff 00f00000-00ffffff
171 0b01 31MB RAM / 1MB Peri 00000000-01efffff 01f00000-01ffffff
172 0b10 64MB RAM / 1MB Peri 00000000-03efffff 03f00000-03ffffff
173 0b11 127MB RAM / 1MB Peri 00000000-07efffff 07f00000-07ffffff
175 Set BSKZ[1:0] to 0b01 for U-Boot.
176 This mode is the most handy because EA[24] is always supported by the save pin
177 mode of the system bus. On the other hand, EA[25] is not supported for some
178 newer SoCs. Even if it is, EA[25] is not connected on most of the boards.
