* MLK-10496: Check the PL310 version for applying erratakk4.4.3_2.0.1imx_v2014.04_kk4.4.3_2.yNitin Garg2015-04-13-8/+15
| | | | | | | | | | | Apply errata based on PL310 version instead of compile time. Also set Prefetch offset to 15, since it improves memcpy performance by 35%. Don't enable Incr double Linefill enable since it adversely affects memcpy performance by about 32MB/s and reads by 90MB/s. Tested with 4K to 16MB sized src and dst aligned buffer.

* MLK-10576 ARM: i.MX6: exclude the ARM errata from i.MX6 UP systemNitin Garg2015-04-13-0/+3
| | | | | | | | | | | | | | | | The ARM errata 751472, 794072, 761320, 845369 only applied to the following configuration: This erratum affects configurations with either: - One processor if the ACP is present - Two or more processors i.MX6 family does not have the ACP and thus only the MPCore system will be impacted, which are the i.MX6DQ, i.MX6DL.

* MLK-10524: iMX6x: Implement workaround for Cortex-A9 errata 845369Nitin Garg2015-04-13-0/+7
| | | | | | | | | | Under very rare timing circumstances, transitioning into streaming mode might create a data corruption. Present on Two or more processors or 1 core with ACP, all revisions. This erratum can be worked round by setting bit[22] of the undocumented Diagnostic Control Register to 1.

* mx6: drop ARM errata 742230Shawn Guo2015-04-13-1/+0
| | | | | | | | | | | | | | | | Commit e9fd66defd7e (ARM: mx6: define CONFIG_ARM_ERRATA_742230) enables errata 742230 for imx6, because it helps remove one reboot issue. However, this errata does not really apply on imx6, because Cortex-A9 on imx6 is r2p10 while the errata only applies to revisions r1p0..r2p2. At a later time, commit f71cbfe3ca5d (ARM: Add workaround for Cortex-A9 errata 794072) adds support of errata 794072, which applies to all Cortex-A9 revisions. As the workaround for both errata are exactly same, it makes a lot more sense to select 794072 instead of 742230 for imx6. Since we already enable 794072 for imx6, it's time to drop errata 742230 to avoid confusion. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* MLK-9953 pcie: disable pcie on imx6sx platformsl5.0.0_1.0.0-alphakk4.4.3_2.0.0-gaRichard Zhu2014-12-04-1/+11
| | | | | | | | | | | | | | | The PCIe support in uboot would bring failures in i.MX6SX PCIe EP/RC validations. Disable PCIe support in uboot here. RootCause: The bit10(ltssm_en) of GPR12 would be set in uboot, thus the i.MX6SX PCIe EP would be cheated that the other i.MX6SX PCIe RC had been configured and trying to setup PCIe link directly, although the i.MX6SX RC is not properly configured at that time.
