ARM: uniphier: fix ROM boot mode for PH1-sLD3
Commit 4b50369fb535 ("ARM: uniphier: create early page table at

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.

We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so
that it is always available to the build system. Otherwise we can run
into cases where we have inconsistent sizes of certain attributes.
Ravi Babu reported offset mismatch of struct dwc3 across files since
commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t").
Since the commit, resource_addr_t points to phys_addr_t, whose size
is dependent on CONFIG_PHYS_64BIT for ARM architecture.
I tried my best to use "select" where possible (for example, ARMv8
architecture) because I think this kind of option is generally user-
unconfigurable. However, I see some of PowerPC boards have 36BIT
defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the
defconfigs for such boards.
CONFIG_36BIT is no longer referenced, so all of the defines were

The tools/moveconfig.py has a feature to cleanup #define/#undef's

For example, when we are moving CONFIG_FOO and its define is
surrounded by #ifdef ... #endif, like follows:
#ifdef CONFIG_BAR
# define CONFIG_FOO
#endif
The header cleanup will leave empty #ifdef ... #endif:
#ifdef CONFIG_BAR
#endif
Likewise, if a define line between two blank lines
<blank line>
#define CONFIG_FOO
<blank lines.
... is deleted, the result of the clean-up will be successive empty
lines, which is a coding-style violation.
It is tedious to remove left-over garbage lines manually, so I want
the tool to take care of this. The tool's job is still not perfect,
so we should check the output of the tool, but I hope our life will
be much easier with this patch.

capable off we can get always do the correct thing for the barrier. The
