-Subject: [PATCH] Revert "MIPS: BCM47XX: Enable 74K Core ExternalSync for PCIe
- erratum"
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This reverts commit 2a027b47dba6b77ab8c8e47b589ae9bbc5ac6175.
-
-Enabling ExternalSync caused a regression for BCM4718A1 (used e.g. in
-Netgear E3000 and ASUS RT-N16): it simply hangs during PCIe
-initialization. It's likely that BCM4717A1 is also affected.
-
-I didn't notice that earlier as the only BCM47XX devices with PCIe I
-own are:
-1) BCM4706 with 2 x 14e4:4331
-2) BCM4706 with 14e4:4360 and 14e4:4331
-it appears that BCM4706 is unaffected.
-
-While BCM5300X-ES300-RDS.pdf seems to document that erratum and its
-workarounds (according to quotes provided by Tokunori) it seems not even
-Broadcom follows them.
-
-According to the provided info Broadcom should define CONF7_ES in their
-SDK's mipsinc.h and implement workaround in the si_mips_init(). Checking
-both didn't reveal such code. It *could* mean Broadcom also had some
-problems with the given workaround.
