[U-Boot] [PATCH v3 065/108] x86: Disable microcode section for FSP2

Simon Glass sjg at chromium.org
Mon Oct 21 03:38:30 UTC 2019


At present we don't support loading microcode with FSP2. The correct way
to do this is by adding it to the FIT. For now, disable including
microcode in the image.

- Drop unnecessary #else part of CONFIG_HAVE_MICROCODE

Changes in v2: None
