PS27, Line 96: 			"SerialIoUartDebugEnable to %d\n", FSP_LOG, FSP_LOG_DEFAULT);
It’s in the coding style, [section *Breaking long lines and strings*](https://doc.coreboot.org/contributing/coding_style.html#breaking-long-lines-...):
> However, never break user-visible strings such as printk messages, because that breaks the ability to grep for them.
