84ccd791af ARM: UniPhier: move pin_init() to board_early_init_f()
Currently, I/O pin settings are not necessary for SPL.
The board_early_init_f() seems a suitable place to call pin_init().

b4ad44baab ARM: UniPhier: add UART initialization routine for low-level debug
The low-level debugging functions are useful to debug the early boot
stage where the full UART driver is not available.

UniPhier SoCs need to initialize the UART port 0 to use this feature.
The initialization routine is called at the very entry of the
lowlevel_init().

b67932e3e7 ARM: UniPhier: call pin_init() also in the normal boot
CONFIG_UNIPHIER_SERIAL has been moved to Kconfig and
it is defined in ./.config but not in spl/.config,
so pin_init() should be called from the normal image
so that UART works correctly.

4f25481b83 ARM: UniPhier: consolidate board_postclk_init() function
This commit merges
  arch/arm/cpu/armv7/uniphier/ph1-*/board_postclk_init.c
to
  arch/arm/cpu/armv7/uniphier/board_postclk_init.c

Because PH1-Pro4 does not have the BCU block, add __weak to
bcu_init().

d064cbffff dm: serial: use Driver Model for UniPhier serial driver
This commit converts UniPhier on-chip serial driver to driver model.

Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)

Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.

Tested on UniPhier PH1-LD4 ref board.
