The unicore32 port do not seem maintained for a long time now, there is no
upstream toolchain that can create unicore32 binaries and all the links to
prebuilt toolchains for unicore32 are dead. Even compilers that were
available are not supported by the kernel anymore.
Guenter Roeck says:
I have stopped building unicore32 images since v4.19 since there is no
available compiler that is still supported by the kernel. I am surprised
that support for it has not been removed from the kernel.
Remove unicore32 port.

Those files got moved, but cross-references still point to the

ioremap has provided non-cached semantics by default since the Linux 2.6
days, so remove the additional ioremap_nocache interface.

unicore32 supports STRICT_DEVMEM, so it needs devmem_is_allowed(), like
some of other architectures have done (e.g. arm, powerpc, x86 ...).
The related error with allmodconfig:
CC drivers/char/mem.o
drivers/char/mem.c: In function ârange_is_allowedâ:
drivers/char/mem.c:69: error: implicit declaration of function âdevmem_is_allowedâ
make[2]: *** [drivers/char/mem.o] Error 1

Disintegrate asm/system.h for Unicore32. (Compilation successful)
The implementation details are not changed, but only splitted.
BTW, some codestyles are adjusted.

For the commit <f1ecc69838a2d7c8a3e1909f637d4083c071777d> has changed
xlate_dev_mem_ptr definition in asm-generic/io.h for the systems with

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.
Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

1. remove __REG macro
2. add (void __iomem *) to io_p2v macro
3. add (phys_addr_t) to io_v2p macro
4. add PKUNITY_AHB_BASE and PKUNITY_APB_BASE definitions
5. modify all PKUNITY_mmio_BASEs from physical addr to virtual addr
6. adjust prefix macro for all usage of PKUNITY_mmio_BASEs
