59fe23c2e0 ARM: uniphier: optimize ProXstream2 UMC init code with "for" loop
Now this code can be re-written with a "for" statement instead of
calling the same function multiple times.

46abfcc99e ARM: uniphier: rework struct uniphier_board_data
This commit reworks "struct uniphier_board_data" with an array of
DRAM channel data in it.  It will allow further cleanups by means of
"for" statements that iterate over the DDR channels.

f775c09d00 ARM: uniphier: adjust DDR clock delay line for ProXstream2
It turned out that DDR channel 2 was not working on ProXstream2
Vodka board.  Add the missing ACBLDR0 register setting to adjust
the delay between the clock lines and the address/command lines.

126f9bad77 ARM: uniphier: fix makefiles to build cmd_ddr(m)phy.c
The U-Boot proper building needs to descend arch/arm/mach-uniphier/dram
to build these commands.

84a7562e49 ARM: uniphier: support some more DRAM use cases on PH1-Pro4 boards
Some of PH1-Pro4 boards are equipped with larger amount of DRAM than
the reference board.  Add UMC settings to support them.

The if block does the same as the else block does.  The conditional
is not necessary at all.

93d92d46cd ARM: uniphier: add dump command for DDR Multi PHY registers
The ProXstream2/PH1-LD6b is integrated with a new IP for DDR PHY
which is not register-compatible with the former SoCs.
Add a new command to support the register dump of this IP.

15607d0d94 ARM: uniphier: add DRAM init code for ProXstream2/PH1-LD6b
As mentioned in the log of commit 019df879a9 (ARM: uniphier: add
ProXstream2 and PH1-LD6b support), the DRAM init code was missing
for a long time.  Finally, here it is.  SPL works now.

more at home in the dram subdirectory.

33886693b6 ARM: uniphier: merge umc/ and ddrphy/ into a single directory
The UMC (Universal Memory Controller) and the DDR PHY block are
highly related to each other.  It is better to have both code in the
same directory.
