e793207bb6 arch/risc-v/src/mpfs: Add a config option for enabling L2 cache
Make a separate config flag for enabling L2 cache. This is on by
default when compiling a standalone/bootloader configuration, but
can also be disabled for special cases, such as memory testing

4b6c9915fe arch: qemu-rv: Fix timer and IPI handling for BUILD_KERNEL+SMP
Summary:
- I noticed that the OS timer sometimes proceeds fast when
  a task is scheduled to run on CPUO via IPI.
- Actually, qemu-rv implementation shares supervisor software
  interrupt for both timer and IPI on CPU0.
- This commit fixes this issue.

Impact:
- qemu-rv only

373568f63a mpfs_mm_init.c: Ensure the L3 page table size is large enough
Run-time check for L3 page table size, to ensure it is large enough
to map all of the kernel memory.

NOTE: The check has to be run-time, as KFLASH_SIZE/KSRAM_SIZE are really
linker relocation symbols, and thus cannot be utilized compile-time.

dbc9a5ffa2 riscv_mmu: Add some basic sanity checks for section boundaries
L3 table maps 2MB of memory, this brings an implicit requirement for
any L3 region to be aligned to 2MB. This commit adds build time sanity
checks to ensure this requirement is met.

For other SvXX architectures the boundary requirement (might be) is
different.

task0 -> task1                      task2 -> task0
1. remove task0 form runninglist
2. take task1 as new tcb
3. add task0 to blocklist
4. clear spinlock
                                    4.1 remove task2 form runninglist
                                    4.2 take task0 as new tcb

ff05cc593f risc-v/mmu: Fix L3 mappings for kernel, and mpfs protected mode userspace
The L3 mapping function was just way too simplistic. Depending on memory
configuration it either works or not.

Noticed that with icicle:pnsh the software crashes due to instruction
page fault, reason is the map_region() implementation that does not
work for regions that are not aligned to 2MB (the L2 page size).

Implemented an extremely simplistic page table allocator for the L3
references, that should once and for all get rid of the L3 mapping issue.

NOTE: gran_alloc() cannot be used at this point, it is too early for it.

5cedf1ef2a risc-v/mpfs: usb: fix usb restart
Issuing the following commands doesn't succeed:
  - conn
  - disconn
  - conn
This USB driver doesn't even disconnect without this patch.

If the USB driver has been started from another hart, closing it
will not disable the PLIC interrupt. This means it's possible many
harts get the USB interrupt and thus make the USB look very unstable.

Fix these problems by disconnecting the USB via the USB_POWER
register at shutdown and disabling the interrupt at shutdown. Also
clear the software internals via the mpfs_sw_setup() for the conn /
disconect loop to succeed.

90d9b6b8ac risc-v/mpfs: usb: fix infinite loop issue
mpfs_write_tx_fifo() gets stuck in the following case:
  - CDCACM is used
  - ttyACM0 is opened and then closed from the remote end,
    such as Linux or Windows
  - data is written into ttyACM0 from NuttX
  - tx fifo will never get empty and the system is stuck

Fix this by issuing an error code if the transmit fifo doesn't

nxsig_usleep() will wait for the next timer tick which is way

This causes severe performance problems. Fix this by polling the

e0291b1ce8 risc-v/mpfs: usb: configure fifos properly
RX_FIFO_ADDRs and TX_FIFO_ADDR were misconfigured. These addresses
overlapped causing data corruption during high USB loads. For
example, data corruption was present during the following conditions:

  1. Composite USB driver was used (CDC/ACM + Mass storage)
  2. /dev/ttyACM0 was accessed instantly from Linux side when
     starting up.
  3. Training data was sent to /dev/ttyACM0 from NuttX from the
     very beginning periodically.

It was observed that while Mass storage was negotiating, sometimes
data sent from NuttX to Linux via CDC/ACM was corrupt, although it
was sent properly on the TX fifo.

Also, don't access TXCSRL_REG_EPN_TX_FIFO_NE_MASK for EP0 as it's
not applicable.

3ea7d4bab4 risc-v/mpfs: amend OpenSBI to utilize IHC
Linux kernel uses M-mode trap for handling Inter-Hart Communication (IHC).
This patch provides all the required functionalities for this purpose.
Previously, HSS bootloader was required. Now, NuttX is run as the
bootloader providing OpenSBI vendor extensions instead. This setup has
been tested on the following configuration:

 - Hart 0 has NuttX in bootloader mode with OpenSBI
 - Hart 1 unused
 - Hart 2 has NuttX configured at 0xa2000000
 - Hart 3 has U-boot / Linux kernel (at 0x80200000)
 - Hart 4 has U-boot / Linux kernel (at 0x80200000)

Upon startup, NuttX on hart 0 will initialize SD-card driver, loads
the hart 2 NuttX from the SD-card and loads the U-boot to 0x80200000.
Also the nuttx.sbi -binary is loaded from SD-card into address 0x80000000,
which is also marked as reserved area in the Linux kernel device tree (for
the chuck 0x80000000 - 0x80200000).

Hart 2 NuttX waits until Linux kernel (IHC master) is started. After the
initial handshake, RPMsg / virtIO bus along with the IHC may be used for
proper AMP mode.

77e36d1acc risc-v/mpfs: introduce IHC driver
This provides an example of Asymmetric Multiprocessing (AMP). The
master from Linux sends pings that this NuttX echoes back. The system
uses RPMsg from OpenAMP.

The Inter-Hart Communication module is present in the vendor's software
stack with the tag "2021.11". The software is present on github at the
polarfire-soc project. The following conditions must be met:

 1. FPGA programmed with 2021.11 software
 2. HSS (Vendor bootloader) with 2021.11 software
 3. U-boot and Linux kernel from 2011.11 software

Currently the IHC works as a slave only on the hart number 4.

On the NuttX side, this patch uses rptun that incorporates rpmsg and
virtio. If it used only rpmsg and virtio, the future maintenance would
likely be much heavier. Using rptun also simplifies many things.

Upon success, the master side from Linux may issue an example test:

root@icicle-kit-es-amp:/opt/microchip/amp/rpmsg-pingpong# ./rpmsg-pingpong

However, the rpmsg-pingpong.c (compiled on target with gcc), may need to
be modified as seen below to match the device id:
 - char *rpmsg_dev="virtio0.rpmsg-amp-demo-channel.-1.0";
 + char *rpmsg_dev="virtio0.rpmsg-amp-demo-channel.-1.1024";

This work uses a separate linker script. Due to a bug yet unknown to date,
a small NuttX, when loaded by the vendor HSS bootloader, will cause the
Linux kernel to hang at boot. Thus, the binary size is increased with
a section 'filler_area' whose only purpose is to increase the image size
so that the Linux kernel will boot up.

9af8b740e6 Elf loader: give temporary write access to user .text memory
When the .elf file is loaded from disk, the kernel must be given write
access to the allocated .text section in the task's address environment.

The access is removed after the elf is loaded and relocations are done.

NOTE:
The reason this works for the ARM implementation, is that the ARM MMU
can be configured to give write access for the privileged mode, but
revoke write access for the user mode.

Regardless, it would be smart to revoke write access even for the
kernel, when the kernel does not need it. This framework allows doing
that, if someone wishes to take up the task.

57127b9429 RISC-V: Initial support for CONFIG_BUILD_KERNEL
This implements initial support for kernel build (address environments,
page allocator) for RISC-V.

This is done a bit differently compared to the ARMV7 implementation:

- Support implemented for Sv39 MMU, however the implementation should be
  extensible for other MMU types also.
- Instead of preserving and moving the L1 references around, a canonical
  approach is used instead, where the page table base address register
  is switched upon context switch.
- To preserve a bit of memory, only a single L1/L2 table is supported,
  this gives access to 1GiB of virtual memory for each process, which
  should be more than enough.

Some things worth noting:
- Assumes page pool is mapped with vaddr=paddr mappings
- The CONFIG_ARCH_XXXX_VBASE and CONFIG_ARCH_XXXX_NPAGES values are
  ignored, with the exception of CONFIG_ARCH_DATA_VBASE which is used
  for ARCH_DATA_RESERVE
- ARCH_DATA_RESERVE is placed at the beginning of the userspace task's
  address environment

04f81ecddb arch: risc-v: Do not enable FPU for K210 with QEMU
Summary:
- I noticed that maix-bit:smp does not work with QEMU.
- Actually, QEMU supports sifive_u (not K210) but it works
  if FPU is disabled.
- This commit fixes this issue.

Impact:
- K210 with QEMU only

Testing:
- Tested with qemu-5.2
