| config SOC_AMD_COMMON_BLOCK_CAR |
| bool |
| help |
| This option allows the SOC to use a standard AMD cache-as-ram (CAR) |
| implementation. CAR setup is built into bootblock and teardown is |
| in postcar. The teardown procedure does not preserve the stack so |
| it may not be appropriate for a romstage implementation without |
| additional consideration. If this option is not used, the SOC must |
| implement these functions separately. |
| This is only used for AMD CPU before family 17h. From family 17h on |
| the RAM is already initialized by the PSP before the x86 cores are |
| released from reset. |

| help |
| From family 17h on AMD CPUs/APUs don't use cache as RAM (CAR) any |
| more, since the RAM initialization is already done by the PSP when |
