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.

risc-v/mpfs: ihc: reorganize ihc Currently the IHC (Inter Hart Communication) depends on OpenAMP and rptun. However, the bootloader portion of the IHC doesn't need either of them. Now they are wasting a lot of bootloader space. Reorganize the bootloader portion into a separate file 'mpfs_ihc_sbi.c'. This file contains the OpenSBI vendor extensions, or the only required functionalities for the bootloader. On the other hand, 'mpfs_ihc.c' contains the non-bootloader code. This patch also makes it possible to utilize 2 RPMSG channels. This has been tested so that 2 separate NuttXs on harts 1 and 2 communicate with Linux kernel that runs on harts 3 and 4. New configuration files are added as well: - rpmsg-ch1: sample config for RPMSG - rpmsg-ch2: sample config for another RPMSG channel - rpmsg-sbi: sample bootloader config for RPMSG/OpenSBI Signed-off-by: Eero Nurkkala <eero.nurkkala@offcode.fi>

This file contains the OpenSBI vendor extensions, or the only required functionalities for the bootloader. On the other hand, 'mpfs_ihc.c' contains the non-bootloader code. This patch also makes it possible to utilize 2 RPMSG channels. This has been tested so that 2 separate NuttXs on harts 1 and 2 communicate with Linux kernel that runs on harts 3 and 4. New configuration files are added as well: - rpmsg-ch1: sample config for RPMSG - rpmsg-ch2: sample config for another RPMSG channel - rpmsg-sbi: sample bootloader config for RPMSG/OpenSBI Signed-off-by: Eero Nurkkala <eero.nurkkala@offcode.fi>

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.

risc-v/mpfs: ihc: reorganize ihc Currently the IHC (Inter Hart Communication) depends on OpenAMP and rptun. However, the bootloader portion of the IHC doesn't need either of them. Now they are wasting a lot of bootloader space. Reorganize the bootloader portion into a separate file 'mpfs_ihc_sbi.c'.
