Yaxing Guo d6328edc03 dts: kvm-v2: Add no-imsic-ipi in imsic_s node 
There is a hardware issue of losing IPI interrupt when using imsic ipi.
Add this quir property to use clint IPI instead.

Yaxing Guo 8dcb5db893 irqchip: riscv-imsic: Add no-imisc-ipi quirk property 
To control whether to use imsic ipi.

Context is that kmh-v2 have known issue that the path from imisic IPI
to CPU might not work sometimes. And the workaround is to use clint IPI
instead.

commit edf2d546bf ("riscv: patch: Flush the icache right after

flush in patch_text_nosync() and patch_text_set_nosync() functions, so
reintroduce them.

YunFeng Yang de4a75917c dts: add rngseed for early entropy init 
The purpose of the rngseed device tree node:
It specifies the seed data source for the random number generator during early boot,
ensuring better entropy initialization for the system.

When running multi-core apache on PLDM, the accumulation of entropy on PLDM is very
slow, which causes geturandom to run for a long time. Add rngseed node to speed up
the initialization of geturandom function.

The relevant task links are as follows:

Yaxing Guo 73963d3155 imsic_test_driver: 
Use for system testing for multi-core IMISC.
In this version, it is no need to add imsic_test node in dts.

It will create an imsic_test directory under /sys/kernel/debugfs/
after mount debugfs.

Under the imsic_test/, there are three debug file:
count, dump_all.

User can allocate any number of interrupts through "echo XX > count".

And observe the test status through "cat dump_all" of all allocated
interrupts.

After echo a number into count, corresponding number of directories
will be created under imsic_test named "0", "1", "2" ... which each
represents an interrupt to be tested.

Under the director of interrupts, there are 5 files:

affinity:
The cpu affinity of this interrupt. You can set the affinity of this
interrupt through "echo cpu_id > affinity".And get the its affinity
through "cat affinity".

hwirq:
The hwirq of this interrupt. You can get the its hardware number
through "cat hwirq".

times:
Recording the times the interrupt was triggered. You cat get this
number through "cat times".
More detailed, you can echo cpu_id to times, then when you get its
numbers, you will receive the number of times the interrupt is trigger
on that CPU, and in the same situation, you will get total number of times
on all of the CPUs directly do "cat times".

trigger:
Trigger this interrupt once.
You can trigger through "echo 1 > trigger"

virq:
The virq(linux irq) of this interrupt.
You can get this through "cat virq".

Anton Blanchard c3aabf7bfe riscv: Fix toolchain vector detection 
A recent change to gcc flags rv64iv as no longer valid:

   cc1: sorry, unimplemented: Currently the 'V' implementation
   requires the 'M' extension

and as a result vector support is disabled. Fix this by adding m
to our toolchain vector detection code.

Sui Jingfeng 5fbdb4bdad riscv: bosc: minimal_defconfig: Enable FUTEX to allow run spec test 
The minimal_defconfig didn't enable CONFIG_FUTEX before, which will cause
the kernel can not run the spec tests. When run omnetpp_run.sh，it report
"the futex facility returned an unexpected error code"

Comments from help of CONFIG_FUTEX:

Disabling the CONFIG_FUTEX option will cause the kernel to be built
without support for "fast userspace mutexes".  The resulting kernel
may not run glibc-based applications correctly.

Sui Jingfeng 5336519f86 riscv: Add a minimal defconfig for CPU simulation purpose 
It should also be able to use on FPGA environment

Note: it require you specify the directory of riscv-rootfs, for example:

export RISCV_ROOTFS_HOME=/home/user/WorkSpace/riscv-rootfs

Usage:

make ARCH=riscv CROSS_COMPILE=riscv64-unknown-linux-gnu- minimal_defconfig

Note, compared with the original config, the following options are removed.

-# CONFIG_VT is not set
-# CONFIG_PROC_FS is not set
-# CONFIG_SYSFS is not set
-CONFIG_PRINTK_TIME=y

config:

Remove CONFIG_INITRAMFS_ROOT_UID=0 and CONFIG_INITRAMFS_ROOT_GID=0,
because they are zero by default.
