ef07a99b08 ARM: uniphier: refactor Support Card init code
Splitting reset assertion (support_card_reset) and deassertion
(support_card_init) is not adding much value any more.  Handle
all the initialization of Support Card in support_card_init(),
then remove support_card_reset().

Also, detect_num_flash_banks() can have a static qualifier.

8d6c99c66f ARM: uniphier: refactor MEMCONF init code
Currently, memconf-sld3.c and memconf-pxs2.c duplicate the code.

There are 3 patterns in terms of MEMCONF init:
  - DRAM 2 channels: LD4, sLD8, Pro4, Pro5, LD11
  - DRAM 3 channels: sLD3
  - DRAM 3 channels (Ch2 is disable by MEMCONF[21]): Pxs2, LD20

All of them can be moved into a single file by a little more
refactoring.

ebc4ef61d7 spl: Add a name to the SPL load-image methods
It is useful to name each method so that we can print out this name when

preparation for unifying this, add a name to each method.

The name is only available if we have libcommon support (i.e can use

499c8679be ARM: uniphier: display revision of Micro Support Card 3.6.x kindly
The revision of the original support card (rev 3.5, rev 3.6) fits in
the 8 bit width revision register.  When it was extended in a weird
way, it was versioned in the format of "3.6.x" (where it should have
been "3.7", of course).  What is worse, only the sub-level version
"6.x" was recorded in the 8 bit width register, completely ignoring
the compatibility of the revision register format.

This patch saves madly-versioned support cards by assuming the major
version "3" when the MSB 4 bit of the register is read as "6".  With
this, the support card revision that were displayed as "6.10" is now
corrected to "3.6.10".

cases we are mirroring the values used by the Linux Kernel here.  Also,
so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux).  Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

82d075e79f ARM: uniphier: fix ROM boot mode for PH1-sLD3
Commit 4b50369fb5 ("ARM: uniphier: create early page table at
run-time") broke the ROM boot mode for PH1-sLD3 SoC, because the
run-time page table creation requires the outer cache register
access but the page table in the sLD3 Boot ROM does not straight-map
virtual/physical addresses.

The idea here is to check the current page table to determine if
it is a straight map table.  If not, adjust the outer cache register
base.

2b1cdafa9f common: Pass the boot device into spl_boot_mode()
The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.

The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

51ea5a060d ARM: uniphier: reserve memory for DRAM PHY training on PH1-LD20
The DRAM PHY layer on PH1-LD20 is able to calibrate PHY parameters
periodically.  This compensates for the voltage and temperature
deviation and improves the PHY parameter adjustment.  Instead, it
requires 64 byte scratch memory in each DRAM channel for the dynamic
training.  The memory regions must be reserved in DT before jumping
to the kernel.

The scratch area can be anywhere in each DRAM channel, but the DRAM
init code in SPL currently assigns it at the end of each channel.
So, it makes sense to reserve the regions on run-time by U-Boot
instead of statically embedding it in the DT in Linux.  Anyway,
a boot-loader should know much more about memory initialization
than the kernel.
