From 602e8a345a916e91256497e13575d0690cd1565f Mon Sep 17 00:00:00 2001 From: James Hogan Date: Thu, 29 Jan 2015 11:14:10 +0000 Subject: [PATCH] MIPS: Malta: Implement get_c0_fdc_int() Implement the weak get_c0_fdc_int() function for Malta. The Fast Debug Channel (FDC) interrupt is obtained mainly depending on whether a GIC is present. Vectored external interrupt mode isn't yet supported.
