Subject: [U-Boot] [PATCH 6/8] mips: bmips: fix first CPU check
Date: Thu, 13 Apr 2017 17:44:38 +0200 [thread overview]
Message-ID: <1492098280-3259-7-git-send-email-noltari@gmail.com> (raw)
In-Reply-To: <1492098280-3259-1-git-send-email-noltari@gmail.com>
CFE checks CPU Thread in a different way (using register $22):
mfc0 t1, C0_BCM_CONFIG, 3 # $22
li t2, CP0_CMT_TPID # (1 << 31)
and t1, t2
bnez t1, 2f # if we are running on thread 1, skip init
nop
