Commit 654102df2a ("kbuild: add generic support for built-in boot
DTBs") introduced generic support for built-in DTBs.
Select GENERIC_BUILTIN_DTB to use the generic rule.
To keep consistency across architectures, this commit also renames
CONFIG_OPENRISC_BUILTIN_DTB_NAME to CONFIG_BUILTIN_DTB_NAME.

As explained in [1], we would like to remove SLOB if possible.
- There are no known users that need its somewhat lower memory footprint
so much that they cannot handle SLUB (after some modifications by the
previous patches) instead.
- It is an extra maintenance burden, and a number of features are
incompatible with it.
- It blocks the API improvement of allowing kfree() on objects allocated
via kmem_cache_alloc().
As the first step, rename the CONFIG_SLOB option in the slab allocator
configuration choice to CONFIG_SLOB_DEPRECATED. Add CONFIG_SLOB
depending on CONFIG_SLOB_DEPRECATED as an internal option to avoid code
churn. This will cause existing .config files and defconfigs with
CONFIG_SLOB=y to silently switch to the default (and recommended
replacement) SLUB, while still allowing SLOB to be configured by anyone
that notices and needs it. But those should contact the slab maintainers
and linux-mm@kvack.org as explained in the updated help. With no valid
objections, the plan is to update the existing defconfigs to SLUB and
remove SLOB in a few cycles.
To make SLUB more suitable replacement for SLOB, a CONFIG_SLUB_TINY
option was introduced to limit SLUB's memory overhead.
There is a number of defconfigs specifying CONFIG_SLOB=y. As part of
this patch, update them to select CONFIG_SLUB and CONFIG_SLUB_TINY.

I have been using a litex SoC for glibc verification. Update the
default litex config to support required userspace API's needed for the
full glibc testsuite to pass.
This includes enabling the litex mmc driver and filesystems used
in a typical litex environment.

This Kconfig option was removed during v4.19 development in commit
771c035372 ("deprecate the '__deprecated' attribute warnings entirely
and for good") so there's no point to keep it in defconfigs any longer.
FWIW defconfigs were patched with:
--------------------------->8----------------------
find . -name *_defconfig -exec sed -i '/CONFIG_ENABLE_WARN_DEPRECATED/d' {} \;
--------------------------->8----------------------

Simple enough to be compatible with simulation environments,
such as verilated systems, QEMU and other targets supporting OpenRISC
SMP. This also supports our base FPGA SoC's if the cpu frequency is
upped to 50Mhz.

The openrisc toolchain prefix changed a few years ago. No one
