This commit brings in the drivers needed to support OpenAMP. These changes were ported from https://github.com/FishsemiCode/nuttx. The current state: Most drivers do now compile but are not yet verfied.
This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository. Squashed commit of the following: Author: Xiang Xiao <xiaoxiang@pinecone.net> include/nuttx/b2c.h and libx/libc/string: Add non-standard string functions to deal with cases where there are more than 8-bits in a type char. Author: Gregory Nutt <gnutt@nuttx.org> Fix several build issues/missing definitiona needed for OpenAMP build in drivers/. Add OpenAMP code has been reviewed and ran through tools/nxstyle (with all reports accounted for). Author: Xiang Xiao <xiaoxiang@xiaomi.com> tools/: Fix the minor issue in Makefile Author: Gregory Nutt <gnutt@nuttx.org> drivers/rptun/rptun.c: Review for coding standard. Run against tools/nxstyle. tools/LibTargets.mk: Fix some TABs that were turned into spaces by a copy-paste. fs/hostfs: Add configure and build support for hostfs RPC. drivers/timer: Add configure and build support for syslog RTC. drivers/syslog: Add configure and build support for syslog RPC. drivers/serial: Add configure and build support for serial RPC. Kconfig, tools/*.mk. openamp/: Add basic OpenAMP build support. drivers/rptun: Add configure and build support for OpenAMP tunnel drivers. drivers/net: Update Make.defs and Kconfig for OpenSDA support. Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c. These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux. Removed because we want to separate the activities. We will just try to get the basic OpenAMP support in place for now. Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h. These are specific to the Xiaomi application. Author: zhuyanlin <zhuyanlin@pinecone.net> This commit brings in the OpenAMP OS driver/RPC components from https://github.com/FishsemiCode/nuttx. Initial commit is source files only. Additional changes to Kconfig and Make.defs files still needed.
