The max valid number of riscv_excp_names is 23, so the last excpetion "guest_store_page_fault" can not be printed. In addition, the current check of cause is invalid for riscv_intr_names. So introduce riscv_cpu_get_trap_name to get the trap cause name.

In a real world we can have 2 exact same CPUs except for the reset vector address, which is pretty common in the RISC-V core IP licensing business. Normally reset vector address is a configurable parameter. Let's create a 64-bit property to store the reset vector address which covers both 32-bit and 64-bit CPUs.

The Icicle Kit board integrates a PolarFire SoC, with one SiFive's E51 plus four U54 cores and many on-chip peripherals and an FPGA. For more details about Microchip PolarFire Soc, please see: https://www.microsemi.com/product-directory/soc-fpgas/5498-polarfire-soc-fpga Unlike SiFive FU540, the RISC-V core resect vector is at 0x20220000. The following perepherals are created as an unimplemented device: - Bus Error Uint 0/1/2/3/4 - L2 cache controller - SYSREG - MPUCFG - IOSCBCFG More devices will be added later. The BIOS image used by this machine is hss.bin, aka Hart Software Services, which can be built from: https://github.com/polarfire-soc/hart-software-services To launch this machine: $ qemu-system-riscv64 -nographic -M microchip-icicle-kit The memory is set to 1 GiB by default to match the hardware. A sanity check on ram size is performed in the machine init routine to prompt user to increase the RAM size to > 1 GiB when less than 1 GiB ram is detected.

Right now things basically work OK, QEMU maps these registers onto two different register numbers, e.g. fcsr maps to both 68 and 73, and GDB can use either of these to access the register. However, GDB's target descriptions don't really work this way, each register should appear just once in a target description, mapping the register name onto the number GDB should use when accessing the register on the target. Duplicate register names actually result in duplicate registers on the GDB side, however, as the registers have the same name, the user can only access one of these registers. Currently GDB has a hack in place, specifically for RISC-V, to spot the duplicate copies of these three registers, and hide them from the user, ensuring the user only ever sees a single copy of each. In this commit I propose fixing this issue on the QEMU side, and in the process, simplify the fpu register handling a little. I think we should, remove fflags, frm, and fcsr from the two (32-bit and 64-bit) fpu feature xml files. These files will only contain the 32 core floating point register f0 to f31. The fflags, frm, and fcsr registers will continue to be advertised in the csr feature as they currently are. With that change made, I will simplify riscv_gdb_get_fpu and riscv_gdb_set_fpu, removing the extra handling for the 3 status registers.

However, the fixed numbering only exists in the GDB source tree so that GDB, when it connects to a target that doesn't provide a target description, will use a specific numbering scheme. That numbering scheme is designed to be compatible with the first versions of QEMU (for RISC-V), that didn't send a target description, and relied on a fixed numbering scheme. Because of the way that QEMU manages its target descriptions, recording the number of registers in each feature, and just relying on GDB's numbering starting from 0, then I propose that we remove all the fixed numbering from the RISC-V feature xml files, and just rely on the standard numbering scheme. Plenty of other targets manage their xml files this way, e.g. ARM, AArch64, Loongarch, m68k, rx, and s390.
