PS4, Line 70: 	  This option enables DFD (Design for Debug) settings.
Please extend the description in a followup.

PS4, Line 9: 	printk(BIOS_INFO, "[%s]\n", __func__);
This reads like a debug message.

PS4, Line 6: #define CPC_FLOW_CTRL_CFG       0x0C53A814
           : #define RESET_ON_KEEP_EN        BIT(17)
           : 
           : /* DFD dump address and size need to be the same as defined in Kernel DTS. */
           : #define DFD_DUMP_ADDRESS	0x6A000000
           : #define DFD_DUMP_SIZE		(1 * MiB)
Where are these – besides `RESET_ON_KEEP_EN` – used?
