42ca6982ff ARM: UniPhier: enable STDMAC for EHCI
Deassert the reset signal and provide the clock for STDMAC core.
This is necessary for the USB 2.0 host controllers.

d3384bf77e ARM: UniPhier: reset NAND core in SPL for non-NAND boot mode
For all the UniPhier SoCs so far, the reset signal of the NAND core
is automatically deasserted after the PLL gets stabled.
(The bit 2 of SC_RSTCTRL is default to one.)

This causes a fatal problem on the NAND controller of PH1-LD4.
For that SoC, the NAND I/O pins are not set up yet at the power-on
reset except the NAND boot mode.  As a result, the NAND controller
begins automatic device scanning with wrong I/O pins and finally
hangs up.

Actually, U-Boot dies after printing "NAND:" on the console unless
the boot mode latch detected the NAND boot mode.

To work around this problem, reset the NAND core in SPL for non-NAND
boot modes.  If CONFIG_NAND_DENALI is enabled, the reset signal is
deasserted again in U-Boot proper.  At this time, I/O pins have been
correctly set up, the device scanning should succeed.

198a97a6ab ARM: UniPhier: split clkrst_init() into two functions
Split the current clkrst_init() into two functions:

 - early_clkrst_init(): called from SPL
  Deassert the reset signals of the memory controller and some other
  basic cores.

 - clkrst_init(): called from main U-boot
  Deassert the reset signals that are necessary for the access to
  peripherals etc.

27eac5df17 ARM: UniPhier: fix SBC init code
Now UniPhier SoCs only work with CONFIG_SPL and the function
sbc_init() is called from SPL.
The conditional #if !defined(CONFIG_SPL_BUILD) has no point
any more.

a86ac9540e ARM: UniPhier: include <mach/*.h> instead of <asm/arch/*.h>
Since commit 0e7368c6c4 (kbuild: prepare for moving headers into
mach-*/include/mach), we can replace #include <asm/arch/*.h> with
<mach/*.h> so we do not need to create the symbolic link during the
build.
