* target/riscv: Add fw_dynamic_info32 for booting RV32 OpenSBITANG Tiancheng2024-10-301-0/+29
| | | | | | | | | | | | | | RV32 OpenSBI need a fw_dynamic_info parameter with 32-bit fields instead of target_ulong. In RV64 QEMU, target_ulong is 64. So it is not right for booting RV32 OpenSBI. We create a fw_dynmaic_info32 struct for this purpose.

* include: Include headers where neededMarkus Armbruster2023-01-081-0/+2
| | | | | | | | | | | | A number of headers neglect to include everything they need. They compile only if the headers they need are already included from elsewhere. Fix that.

* Clean up header guards that don't match their file nameMarkus Armbruster2022-05-111-2/+3
| | | | | | | | | | | | | Header guard symbols should match their file name to make guard collisions less likely. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

* riscv: Add opensbi firmware dynamic supportAtish Patra2020-07-131-0/+58
OpenSBI is the default firmware in Qemu and has various firmware loading options. Currently, qemu loader uses fw_jump which has a compile time pre-defined address where fdt & kernel image must reside. This puts a constraint on image size of the Linux kernel depending on the fdt location and available memory. However, fw_dynamic allows the loader to specify the next stage location (i.e. Linux kernel/U-Boot) in memory and other configurable boot options available in OpenSBI. Add support for OpenSBI dynamic firmware loading support. This doesn't break existing setup and fw_jump will continue to work as it is. Any other firmware will continue to work without any issues as long as it doesn't expect anything specific from loader in "a2" register.
