This reduces the needed modifications to the mainline Linux kernel and also makes the regmap package work with an out of tree kernel which does not have these modifications. The regmap-core is only added when it is really build as a module. The regmap-core is normally bool so it cannot be built as a module in an unmodified kernel. When it is selected by on other kernel module it will always be selected as build in and it also does not show up in $(LINUX_DIR)/modules.builtin as it is not supposed to be a kernel module. When it is not in $(LINUX_DIR)/modules.builtin the build system expects it to be built as a .ko file. Just check if the module is really there and only add it in that case. This splits the regmap package into multiple packages, one for each bus type. This way only the bus maps which are really needed have to be added. This also splits the I2C, SPI and MMIO regmap into separate packages to not require all these subsystems to build them, on an unmodified upstream kernel this also causes problems in some situations.

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
