5f49845ecc ARM: uniphier: support DDR PHY parameter dump command for LD11
Add the LD11 SoC data and adjuts the printf() format because this is
a 64-bit SoC.  Otherwise, 16-digits pointer addresses would break
the log format.

adf55f63ae ARM: uniphier: refactor DDR PHY parameter dump command
Do not hard-code the number of DX blocks because it is a different
value for LD11 SoC.

Move the macro NR_DATX8_PER_DDRPHY to ddrphy-training.c since it
is the last user.

6dd34ae4c4 ARM: uniphier: rework existing DDR PHY code to reuse for LD11 SoC
The DDR PHY register view of LD11 is slightly different from that
of LD4/Pro4/sLD8, but it will be possible to share the register
macros (and I want to re-use as much code as possible).  Change
the code in the more flexible form.

9c5313dc09 ARM: uniphier: do not run harmful code for USB boot mode of LD11 ES3
The USB boot without the stand-by MPU is available on ES3 or later
of LD11 SoC, but the code in this if-conditional block must not be
run when booting from USB.  Check if the boot device is USB, and
skip the code in the case.

76466bd7be ARM: uniphier: enable clocks to MIO/STDMAC on LD11 if USB is enabled
At the moment, the clk driver is not clever enough to automatically

66e3efebbc ARM: uniphier: insert udelay() just before support_card_reset_deassert()
As for LD11/LD20, we can no longer rely on the udelay() in the PLL
init functions.  udelay(200) is needed here to keep the ethernet
device in the reset state for enough time.  Anyway, 200 usec is
quite short for humans, so nobody cares it.

As I repeated in the ML, I am unhappy with config entries with bare
defaults.  Kick them out of arch/arm/mach-uniphier/Kconfig.

Currently, CONFIG_SPL_SERIAL_SUPPORT is not user-configurable

so I am moving CONFIG_SPL_SERIAL_SUPPORT to defconfigs.

b291671232 ARM: uniphier: merge board init functions into board_init()
Currently, the UniPhier platform calls several init functions in the
following order:

  [1] spl_board_init()
  [2] board_early_init_f()
  [3] board_init()
  [4] board_early_init_r()
  [5] board_late_init()

The serial console is not ready at the point of [2], so we want to
avoid using [2] from the view point of debuggability.  Fortunately,
all of the initialization in [2] can be delayed until [3].  I see no
good reason to split into [3] and [4].  So, merge [2] through [4].
