Cherrry-picked form https://review.openocd.org/c/openocd/+/8070/21 1) OpenOCD has the capability to 'force' a register read from the target. This functionality however silently breaks the register cache: During 'get_reg force' or 'reg <name> force', reg->type->get() is called which will silently overwrite dirty items in the register cache, causing a loss of unwritten register values. This patch fixes that by adding a flush callback for registers, and by using it when it is needed. 2) The register write commands did not have the 'force' flag; this was present for register read commands only. This patch adds it. 3) This patch also introduces the flush_reg_cache command. It flushes all registers and can optionally invalidate the register cache after the flush. For targets which implement the register cache, the flush() callback in struct reg_arch_type should be implemented (in separate patches, by the maintainers of each of the target type). This functionality is also useful for test purposes. Example: - In RISC-V, some registers are WARL (write any read legal) and this command allows to check this behavior. We plan to implement the corresponding callback in the RISC-V target.
