* hw/riscv: virt: Map high mmio for PCIeBin Meng2021-03-041-2/+33
| | | | | | | | | | | | | | Some peripherals require 64-bit PCI address, so let's map the high mmio space for PCIe. For RV32, the address is hardcoded to below 4 GiB from the highest accessible physical address. For RV64, the base address depends on top of RAM and is aligned to its size which is using 16 GiB for now.

| | | | | | | | | | | | | | | RV32 supports 34-bit physical address hence the maximum RAM size should be limited. Limit the RAM size to 10 GiB, which leaves some room for PCIe high mmio space. For 32-bit host, this is not needed as machine->ram_size cannot represent a RAM size that big. Use a #if size test to only do the size limitation for the 64-bit host.

* hw/riscv: sifive_u: Add QSPI0 controller and connect a flashBin Meng2021-03-042-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the QSPI0 controller to the SoC, and connects an ISSI 25WP256 flash to it. The generation of corresponding device tree source fragment is also added. Since the direct memory-mapped mode is not supported by the SiFive SPI model, the <reg> property does not populate the second group which represents the memory mapped address of the SPI flash. With this commit, upstream U-Boot for the SiFive HiFive Unleashed board can boot on QEMU 'sifive_u' out of the box. This allows users to develop and test the recommended RISC-V boot flow with a real world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to L2LIM, then U-Boot SPL loads the payload from SPI flash that is combined with OpenSBI fw_dynamic firmware and U-Boot proper. Specify machine property `msel` to 6 to allow booting from the SPI flash. U-Boot spl is directly loaded via `-bios`, and subsequent payload is stored in the SPI flash image.

* RISC-V: Place DTB at 3GB boundary instead of 4GBAtish Patra2021-01-161-4/+4
| | | | | | | | | | | | | | | | | | | Currently, we place the DTB at 2MB from 4GB or end of DRAM which ever is lesser. However, Linux kernel can address only 1GB of memory for RV32. Thus, it can not map anything beyond 3GB (assuming 2GB is the starting address). As a result, it can not process DT and panic if opensbi dynamic firmware is used. While at it, place the DTB further away to avoid in memory placement issues in future. Fix this by placing the DTB at 16MB from 3GB or end of DRAM whichever is lower.

* hw/riscv: microchip_pfsoc: Correct DDR memory mapBin Meng2020-11-031-6/+44
| | | | | | | | | | | | | | | | | | | | | When system memory is larger than 1 GiB (high memory), PolarFire SoC maps it at address 0x10_0000_0000. Address 0xC000_0000 and above is aliased to the same 1 GiB low memory with different cache attributes. At present QEMU maps the system memory contiguously from 0x8000_0000. This corrects the wrong QEMU logic. Note address 0x14_0000_0000 is the alias to the high memory, and even physical memory is only 1 GiB, the HSS codes still tries to probe the high memory alias address. It seems there is no issue on the real hardware, so we will have to take that into the consideration in our emulation. Due to this, we we increase the default system memory size to 1537 MiB (the minimum required high memory size by HSS) so that user gets notified an error when less than 1537 MiB is specified.

Also return the end address from riscv_find_and_load_firmware(). This tells the caller if a firmware was loaded and how big it is. This can be used to determine the load address of the next image (usually the kernel).

* load_elf: Remove unused address variables from callersBALATON Zoltan2020-09-261-4/+4
| | | | | | | | | | | | | | | | Several callers of load_elf() pass pointers for lowaddr and highaddr parameters which are then not used for anything. This may stem from a misunderstanding that load_elf need a value here but in fact it can take NULL to ignore these values. Remove such unused variables and pass NULL instead from callers that don't need these.
