New description:

 There is a new RISC-V based Beagle based on the Polarfire SOC. This
 project is to create a BSP for that.

 The following is a list of peripherals that have been identified based on
 information from https://www.microchip.com/en-us/products/fpgas-and-plds
 /system-on-chip-fpgas/polarfire-soc-fpgas

 This ticket is related to the BeagleBoard 2022 GSoC effort:
 https://elinux.org/BeagleBoard/GSoC/Ideas-2022#RTEMS_on_RISC-V

 As of 2022/3/1, at least these BSP components are supported:

 * CPU Cores (both E51 and U54)
 * Interrupt controller (PLIC)
 * Timer (CLINT)
 * UART (mmuart, 16550-compatible or close enough)


 Unsupported:

 * Ethernet (mss-gem, not in libbsd or upstream FreeBSD, lwIP support
 unknown)
 * U54 MMU (bare and Sv39 modes)

 There is Linux support under development for this. We need to pursue
 asking for dual-licensing at least the network driver as NXP did for
 qoriq.

 All other peripherals have not been checked for existing support.

 Mentors: Hesham, Kinsey, Joel, Chris, someone from Beagle community
