riscv: cache: Implement i/dcache [status, enable, disable] AndeStar RISC-V(V5) provide mcache_ctl register which can configure I/D cache as enabled or disabled. This CSR will be encapsulated by CONFIG_RISCV_NDS. If you want to configure cache on AndeStar V5 AE350 platform. YOu can enable [*] AndeStar V5 ISA support by make menuconfig. This approach also provide the expansion when the vender specific features are going to join in. Signed-off-by: Rick Chen <rick@andestech.com> Cc: Greentime Hu <greentime@andestech.com>

riscv: ax25: Hide the ax25-specific Kconfig option There is no need to expose RISCV_NDS to the Kconfig menu as it is an ax25-specific option. Introduce a dedicated Kconfig option for the cache ops of ax25 platform and use that to guard the cache ops.

riscv: add run mode configuration for SPL U-Boot SPL can be run in a different privilege mode from U-Boot proper. Add new configuration entries for SPL to allow the run mode to be configured independently of U-Boot proper. Extend all uses of the CONFIG_RISCV_SMODE and CONFIG_RISCV_MMODE configuration symbols to also cover the SPL equivalents. Ensure that files compatible with only one privilege mode are not included in builds targeting an incompatible privilege mode.
