the SoC's boot process instead of letting the SPL load and run the main
U-Boot image.

But, since the u-boot-spl.img (including the 64 byte header) is loaded
by the SoC as the main image, we need to compensate for the header
length to get a correct entry point.

Thus, we subtract the header size from the destination address, so that
the execution address points at the actual entry point of the image.

The current boards ignore both parameters anyway, so this change shouldn't

tail of the second stage loader (= SPL in U-boot terminology).

The size of the second stage loader was 64KB, and it was consistent
across SoCs.  The situation changed when LD20 SoC appeared; it loads
80KB second stage loader, and it is the only exception.

Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is
loaded from the 64KB offset of non-volatile devices.  This means the
signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot
proper image.

Let's move the U-Boot proper image to 128KB offset.  It uses 48KB
for nothing but padding, and we could actually locate the U-Boot
proper at 80KB offset.  However, the power of 2 generally seems a
better choice for the offset address.

ARM: uniphier: detect RAM size by decoding HW register instead of DT

U-Boot needs to set up available memory area(s) in dram_init() and
dram_init_banksize().  It is platform-dependent how to detect the
memory banks.  Currently, UniPhier adopts the memory banks _alleged_
by DT.  This is based on the assumption that users bind a correct DT
in their build process.

Come to think of it, the DRAM controller has already been set up
before U-Boot is entered (because U-Boot runs on DRAM).  So, the
DRAM controller setup register seems a more reliable source of any
information about DRAM stuff.  The DRAM banks are initialized by
preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever),
so this means the source of the reliability is shifted from Device
Tree to such early-stage firmware.  However, if the DRAM controller
is wrongly configured, the system will crash.  If your system is
running, the DRAM setup register is very likely to provide the
correct DRAM mapping.

Decode the SG_MEMCONF register to get the available DRAM banks.
The dram_init() and dram_init_banksize() need similar decoding.
It would be nice if dram_init_banksize() could reuse the outcome
of dram_init(), but global variables are unavailable at this stage
because the .bss section is available only after the relocation.
As a result, SG_MEMCONF must be checked twice, but a new helper
uniphier_memconf_decode() will help to avoid code duplication.
