soc/intel/xeon_sp: Clear reserved field in SRAT
During the ACPI dump of the System Resource Affinity Table (SRAT), it was noticed that the reserved field within the Memory Affinity structure contained a non-zero value. This commit addresses the issue by performing a memset to zero on the reserved field, ensuring the avoidance of any potential problems arising from garbage values. TEST= Build for ibm/sbp1 & make sure SRAT Memory Affinity entries reserved fields read zeroes Signed-off-by: Naresh Solanki <Naresh.Solanki@9elements.com> Change-Id: I4ba697a6bd59054e74c84b98f3d9b517d333a5d8 Reviewed-on: https://review.coreboot.org/c/coreboot/+/75417 Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>
