Linux kernel source tree
ef10bdf9c3
Since SOC_FOO should be deprecated from patch [1], and cleanup for other SoCs is already in the mailing list [2,3,4], we remove the use of SOC_CANAAN and use ARCH_CANAAN for SoCs vendored by Canaan instead from now on. And allows ARCH_CANAAN to be selected for other Canaan SoCs. However, we should keep the config SOC_CANAAN and use def_bool to redirect the symbol temporarily to avoid potential conflict. Since we now have Canaan Kendryte K230 with MMU, ARCH_CANAAN is no longer referred to as K210. There are some special features for K210, like M-Mode No MMU and loader.bin in arch/riscv/Makefile. If we keep ARCH_CANAAN for other Canaan SoCs and remove the K210, the depends on !MMU in Kconfig may confuse some users who try to boot Kernel with MMU on K210, as Damien mentioned in the list [5]. Thus, we introduce a new symbol SOC_CANAAN_K210 for any conditional code or driver selection specific to the K210, so users will not try to build some K210-specific things when MMU is enabled and see it fails to boot on K210.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
