1 config SOC_AMD_COMMON_BLOCK_CAR
4 This option allows the SOC to use a standard AMD cache-as-ram (CAR)
5 implementation. CAR setup is built into bootblock and teardown is
6 in postcar. The teardown procedure does not preserve the stack so
7 it may not be appropriate for a romstage implementation without
8 additional consideration. If this option is not used, the SOC must
9 implement these functions separately.
10 This is only used for AMD CPU before family 17h. From family 17h on
11 the RAM is already initialized by the PSP before the x86 cores are
14 config SOC_AMD_COMMON_BLOCK_NONCAR
17 From family 17h on AMD CPUs/APUs don't use cache as RAM (CAR) any
18 more, since the RAM initialization is already done by the PSP when
19 the x86 cores are released from reset.

41 Add common machine check architecture support. Do not select this

43 SOC_AMD_COMMON_BLOCK_MCAX which will select this one.
