+NOP PHY driver
+
+This driver is used to stub PHY operations in a driver (USB, SATA).
+This is useful when the 'client' driver (USB, SATA, ...) uses the PHY framework
+and there is no actual PHY harwdare to drive.
+
+Required properties:
+- compatible : must contain "nop-phy"
+- #phy-cells : must contain <0>
+
+Example:
+
+nop_phy {
+ compatible = "nop-phy";
+ #phy-cells = <0>;
+};
particular needs this to operate, so that it can allocate the
initial serial device and any others that are needed.
+config SPL_SYS_MALLOC_F_LEN
+ hex "Size of malloc() pool in spl before relocation"
+ depends on SYS_MALLOC_F
+ default SYS_MALLOC_F_LEN
+ help
+ Before relocation, memory is very limited on many platforms. Still,
+ we can provide a small malloc() pool if needed. Driver model in
+ particular needs this to operate, so that it can allocate the
+ initial serial device and any others that are needed.

- $ make CROSS_COMPILE=arm-linux-gnueabihf-
+The source can be configured and built with the following commands:
-LD4 reference board:
- $ make uniphier_ld4_sld8_defconfig
- $ make CROSS_COMPILE=arm-linux-gnueabihf-
+ $ make <defconfig>
+ $ make CROSS_COMPILE=<toolchain-prefix> DEVICE_TREE=<device-tree>
-sLD8 reference board:
- $ make uniphier_ld4_sld8_defconfig
- $ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-sld8-ref
+The recommended <toolchain-prefix> is `arm-linux-gnueabihf-` for 32bit SoCs,

+The device tree marked as (default) can be omitted. `uniphier-pxs2-vodka` is

+Booting 32bit SoC boards
+------------------------
-Burn U-Boot images to NAND
---------------------------
+The build command will generate the following:
+- u-boot.bin
+- spl/u-boot.bin
-Write the following to the NAND device:
+U-Boot can boot UniPhier 32bit SoC boards by itself. Flash the generated images
+to the storage device (NAND or eMMC) on your board.
- spl/u-boot-spl.bin at the offset address 0x00000000
- u-boot.bin at the offset address 0x00020000
-or
+The `u-boot-with-spl.bin` is the concatenation of the two (with appropriate
+padding), so you can also do:
- u-boot-with-spl.bin at the offset address 0x00000000
If a TFTP server is available, the images can be easily updated.
Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
-and then run the following command at the U-Boot command line:
+and run the following command at the U-Boot command line:
- => run nandupdate
+To update the images in NAND:
+ => run nandupdate
-Burn U-Boot images to eMMC
---------------------------
+To update the images in eMMC:
-Write the following to the Boot partition 1 of the eMMC device:
+ => run emmcupdate
- - spl/u-boot-spl.bin at the offset address 0x00000000
- - u-boot.bin at the offset address 0x00020000
-or
+Booting 64bit SoC boards
+------------------------
- - u-boot-with-spl.bin at the offset address 0x00000000
+The build command will generate the following:
+- u-boot.bin
-If a TFTP server is available, the images can be easily updated.
-Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
-and then run the following command at the U-Boot command line:
+However, U-Boot is not the first stage loader for UniPhier 64bit SoC boards.
+U-Boot serves as a non-secure boot loader loaded by [ARM Trusted Firmware],
+so you need to provide the `u-boot.bin` to the build command of ARM Trusted
+Firmware.
