From 2dde122b66b3bf1a4d3c2798fb4b369b66de9309 Mon Sep 17 00:00:00 2001 From: Salvador Arroyo Date: Sat, 23 Feb 2013 22:53:35 +0100 Subject: [PATCH] mips: mips32_pracc_fastdata_xfer() little modification In this function after loading the handler code and the jump code there is a call to wait_for_pracc_rw() to verify that a pracc access is pending. Next the address is read to verify that the handler is running, the address should be at fastdata area. Next, another call is made to wait_for_pracc_rw(). This call is not needed, we now already that a pracc access is pending. Better we call this function before loading the end address to be sure it is loaded correctly.
