1320fa2e55 ARM: uniphier: remove workaround for the NAND write protect
This workaround was previously needed for LD4, Pro4, sLD8, Pro5
SoCs. The boot ROM does not touch this register for PXs2/LD6b or
later.

Now that the reset signal of the Denali NAND controller is always
asserted in board_init() then deasserted in the driver, the
WRITE_PROTECT register gets back to the default value, which means
the write protect is deasserted.

This workaround can go away entirely.

ce4e9ff4d2 ARM: uniphier: move NAND reset assertion to U-Boot proper from SPL
The comment /* deassert reset */ is wrong. It asserts the reset.

It no longer needs to stay in SPL. The NAND controller reset is
handled  in the driver. So, this assert can be moved to the
board_init() of U-Boot proper.

34ded87506 ARM: uniphier: detect register base addresses run-time
Until the last SoC, the register addresses have been hard-coded because
they are always constant. For a planned new SoC, the register bases
will be completely changed. I insist on supporting multiple SoCs/boards
by a single defconfig (uniphier_v8_defconfig) since duplicating similar
defconfig files is a maintenance burden. The base addresses must be
fixed-up at run-time somehow.

Previously, the board init code identified the SoC by reading out the
SG_REVISION register. This is much easier than parsing DT.

You cannot do it any more because the base address of SG will be
changed. The SG_REVISION register exists to read out the SoC ID, but
you never know its address before identifying the SoC. Oh well.

So, the possible solution is to parse the DT, and find out the node
with "*-soc-glue" compatible string. Then, sg_base is set to the value
of the "reg" property. The sc_base is set up likewise.

It is worth noting a pit-fall. Having sc_base and sg_base in the global
scope will make the life easier, but the global variables are poorly
supported before the relocation. In fact, the .bss section overwraps
with DT. Allocating them in the .bss section would break DT. So, I gave
dummy initializers to assign them in the .data section.
