| * riscv: Clear pending interrupts before enabling IPIsSean Anderson2020-07-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | On some platforms (k210), the previous stage bootloader may have not cleared pending IPIs before transferring control to U-Boot. This can cause race conditions, as multiple harts all attempt to initialize the IPI controller at once. This patch clears IPIs before enabling them, ensuring that only one hart modifies shared memory at once. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Rick Chen <rick@andestech.com>

| | | | | | | | | | | | | | | | | In RISC-V, M-mode software can reserve physical memory regions by setting appropriate physical memory protection (PMP) csr. As the PMP csr are accessible only in M-mode, S-mode U-Boot can not read this configuration directly. However, M-mode software can pass this information via reserved-memory node in device tree so that S-mode software can access this information.

In this particular re-sync in order to keep clang support working a number of related changes needed to be pulled in that had been missed previously. Not all of these changes we easily traceable and so have been omitted from the list below. The imported Linux commits are: [From prior to v4.18] 9f3f1fd29976 kbuild: Add __cc-option macro d7f14c66c273 kbuild: Enable Large File Support for hostprogs 6d79a7b424a5 kbuild: suppress warnings from 'getconf LFS_*' 24403874316a Shared library support 86a9df597cdd kbuild: fix linker feature test macros when cross compiling with Clang 0294e6f4a000 kbuild: simplify ld-option implementation [From v4.18 to v4.19] 96f14fe738b6 kbuild: Rename HOSTCFLAGS to KBUILD_HOSTCFLAGS 10844aebf448 kbuild: Rename HOSTCXXFLAGS to KBUILD_HOSTCXXFLAGS b90a368000ab kbuild: Rename HOSTLDFLAGS to KBUILD_HOSTLDFLAGS 8377bd2b9ee1 kbuild: Rename HOST_LOADLIBES to KBUILD_HOSTLDLIBS f92d19e0ef9b kbuild: Use HOST*FLAGS options from the command line 4ab3b80159d4 kconfig: check for pkg-config on make {menu,n,g,x}config 693359f7ac90 kconfig: rename SYMBOL_AUTO to SYMBOL_NO_WRITE f60b992e30ff kbuild: replace $(LDFLAGS) $(ldflags-y) with $(ld_flags) 2fb9279f2c3e kbuild: change ld_flags to contain LDFLAGS_$(@F) c931d34ea085 arm64: build with baremetal linker target instead of Linux when available 5accd7f3360e kconfig: handle format string before calling conf_message_callback() a2ff4040151a kconfig: rename file_write_dep and move it to confdata.c 0608182ad542 kconfig: split out useful helpers in confdata.c adc18acf42a1 kconfig: remove unneeded directory generation from local*config 79123b1389cc kconfig: create directories needed for syncconfig by itself 16952b77d8b5 kconfig: make syncconfig update .config regardless of sym_change_count d6c6ab93e17f kbuild: remove deprecated host-progs variable 56869d45e364 kconfig: fix the rule of mainmenu_stmt symbol c151272d1687 kconfig: remove unused sym_get_env_prop() function 1880861226c1 kconfig: remove P_ENV property type e3fd9b5384f3 scripts/dtc: consolidate include path options in Makefile 4bf6a9af0e91 kconfig: add build-only configurator targets f1575595d156 kconfig: error out when seeing recursive dependency 5e8c5299d315 kconfig: report recursive dependency involving 'imply' f498926c47aa kconfig: improve the recursive dependency report 98a4afbfafd2 kconfig: fix "Can't open ..." in parallel build 9a9ddcf47831 kconfig: suppress "configuration written to .config" for syncconfig 87a32e624037 kbuild: pass LDFLAGS to recordmcount.pl d503ac531a52 kbuild: rename LDFLAGS to KBUILD_LDFLAGS 217c3e019675 disable stringop truncation warnings for now bc8d2e20a3eb kconfig: remove a spurious self-assignment fd65465b7016 kconfig: do not require pkg-config on make {menu,n}config 5a4630aadb9a ftrace: Build with CPPFLAGS to get -Qunused-arguments Note that this adds new cleanup work to do in that we should adapt the shared library support we have to what is now upstream.

| | | | | | | | | | | | | | | | | | | | | | Few v0.1 SBI calls are being replaced by new SBI calls that follows v0.2 calling convention. Implement the replacement extensions and few additional new SBI function calls that makes way for a better SBI interface in future.

| * riscv: Introduce a new config for SBI v0.1Bin Meng2020-03-173-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now have SBI v0.2 which is more scalable and extendable to handle future needs for RISC-V supervisor interfaces. Introduce a new config and move all SBI v0.1 code under that config. This allows to implement the new replacement SBI extensions cleanly and remove v0.1 extensions easily in future. Currently, the config is enabled by default. Once all M-mode software, with v0.1, is no longer in use, this config option and all relevant code can be easily removed.
