There is code that is specifically for RGMII_TXID interface, but this
will never get used because the code checks that the RGMII interface
is RGMII_ID to RGMII_RXID; RGMII_TXID is after this.

To fix this and avoid similar problems in the future, use the

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.

important during execution it is strongly recommended to use recent
ARC toolchain, and so we're now referring to arc-2016.09 which is the

Revert "armv8: release slave cores from CPU_RELEASE_ADDR"

This reverts commit 8c36e99f211104fd7dcbf0669a35a47ce5e154f5.

There is misunderstanding in commit 8c36e99f2111 ("armv8: release
slave cores from CPU_RELEASE_ADDR").  How to bring the slave cores
into U-Boot proper is platform-specific.  So, it should be cared
in SoC/board files instead of common/spl/spl.c.  As you see SPL
is the acronym of Secondary Program Loader, there is generally
something that runs before SPL (the First one is usually Boot ROM).

How to wake up slave cores from the Boot ROM is really SoC specific.
So, the intention for the spin table support is to bring the slave
cores into U-Boot proper in an SoC specific manner.  (this must be
done after relocation.  see below.)

If you bring the slaves into SPL, it is SoC own code responsibility
to transfer them to U-Boot proper.  The Spin Table defines the
interface between a boot-loader and Linux kernel.  It is unrelated
to the interface between SPL and U-Boot proper.

One more thing is missing in the commit; spl_image->entry_point
points to the entry address of U-Boot *before* relocation.  U-Boot
relocates itself between board_init_f() and board_init_r().  This
means the master CPU sees the different copy of the spin code than
the slave CPUs enter.  The spin_table_update_dt() protects the code
*after* relocation.  As a result, the slave CPUs spin in unprotected
code, which leads to unstable behavior.

arm64: spin-table: add more information in Kconfig help

This feature seems to be sometimes misunderstood.  The intention is:

[1] Bring the slaves into the U-Boot proper image, not SPL (unless
    you have a special reason to do otherwise).

[2] The operation must be done in a board (SoC) specific manner
    since how to wake the slaves from the Boot ROM is SoC specific.

[3] The slaves must enter U-Boot proper after U-Boot relocates
    itself because the "cpu-release-addr" property points to the
    relocated memory area.

[2] is already explained in the help.  We can make [1] even clearer
by mentioning "U-Boot proper" instead of "U-Boot".  [3] is missing,
