CONFIG_SPL_SYS_[DI]CACHE_OFF: add
While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances where these configuration items are conditional on SPL. This commit adds SPL variants of these configuration items, uses CONFIG_IS_ENABLED(), and updates the configurations as required. Acked-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Trevor Woerner <trevor@toganlabs.com> [trini: Make the default depend on the setting for full U-Boot, update more zynq hardware] Signed-off-by: Tom Rini <trini@konsulko.com>
