* MLK-12531 mx6sxsabresd: Add CM4 fast boot up demoYe Li2017-04-05-0/+2
| | | | | | | | | | | | | | | | | | This is a demo that CM4 will boot up by u-boot without typing any command. It boots up at u-boot early init, try to minimize the time from power up to the CM4 running. Since CM4 runs on QSPI NOR XIP, we have to disable the QSPI driver in u-boot to avoid conflict. RDC for shared GPIO1 is added, but not enabled, because the kernel is not ready for shared GPIO1. Users can uncomment the CONFIG_IMX_RDC to enable it. Some legacy codes in mx6sxsabreauto are removed. We only need this work on mx6sxsabresd as a demo. Signed-off-by: Ye Li <ye.li@nxp.com> (cherry picked from commit f66842f79d4e33ace45762466eed23a86d367642)

* MLK-12495 mx6: Add LDO bypass supportYe Li2017-04-05-2/+162
| | | | | | | | | | | | | | | | Port LDO bypass support from v2015 to support the features: 1. Add check for 1.2GHz core speed. If Speed grading fuse is for 1.2GHz, enable LDO bypass and setup PMIC voltages. LDO bypass is dependent on the flatten device tree file. 2. We set WDOG_B in set_anatop_bypass() before, because it is the only case, but now on i.mx6sabreauto board, we didn't use ldo-bypass mode, but have to use WDOG_B to reboot whole board, so split these code to independent function so that board file can call it freely.

* MLK-14261-1 mx6solo: Rename the CONFIG_MX6SOLO to CONFIG_MX6SYe Li2017-04-05-1/+1
| | | | | | | | | | | | | Since there is already CONFIG_MX6S used for i.MX6 SOLO in u-boot codes, we don't need to add new CONFIG_MX6SOLO. Rename the existing CONFIG_MX6SOLO to CONFIG_MX6S. Additional, for CONFIG_MX6S, we should select CONFIG_MX6DL. The major difference for these two chips are core number and DDR controller. So all duallite relevant definitions can apply to solo. User can combine the two configs if any code only apply to solo or duallite. Signed-off-by: Ye Li <ye.li@nxp.com>
* MLK-10647 armv7: Fix Dcache disable issue on i.MX7Ye.Li2017-04-05-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The issue on the i.MX7D is that, there is one cache-able memory access between the L1 and L2 cache flush by calling the flush_dache_all-> v7_maint_dcache_all() [Flush L1 and L2 cache) which written in the C code. L1-cache-flush -> This will flush L1 cache to L2 cache in the end. Cache-able memory access -> This will have the chance cause the L1 line-fill with dirty data from L2 cache(L1 cache-line dirty, L2 clean) L2-cache-flush -> This will only flush L2 cache to L3, but still some dirty data on the L1 cacheline. After C & M bit clean, -> The dirty data on the L1 cache line lost, which will cause memory coherent issue if that dirty cache line has some useful data The only problem here is: there is one cache-cable memory access between L1 and L2 cache flush. This patch should works fine on the i.MX6 and i.MX7. The second cache flush have zero impact on the i.MX6, but this is really need for the i.MX7D platform due to the L1 line-fill during the first dcache_flush. And the second flush will not bring in the L1 dirty cache line due to the C bit is clear now, which means the dcache is disabled.

| | | | | | | | | | | | | | | | | | | From i2c spec, if device pull down the SDA line that causes i2c bus dead, host can send out 9 clock to let device release SDA. But for some special device like pfuze100, it pull down SDA line and the solution cannot take effort. The patch just add NACK and STOP signal after 8 dummy clock, and pmic can release SDA line after the recovery. Test case catch 375 times of i2c hang, and all are recovered.

* MLK-10524: iMX6x: Implement workaround for Cortex-A9 errata 845369Nitin Garg2017-04-05-0/+10
| | | | | | | | | | | 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.

| | | | | | | | | Use syscounter for i.MX6UL platform as default timer, not use GPT. Add a CONFIG_GPT_TIMER for selecting GPT. Using CONFIG_SYSCOUNTER_TIMER for selecting system counter. Signed-off-by: Ye Li <ye.li@nxp.com> (cherry picked from commit 1c27c9ecf80b3cc63a7c9751ebfd11755f847b1d)
* ENGR00325255 pcie:enable pcie support on imx6sx sdYe Li2017-04-05-5/+35
| | | | | | | | | | | | | | | | | Enable pcie support in uboot on imx6sx sd boards - enable_pcie_clock should be call before ssp_en is set, since that ssp_en control the phy_ref clk gate, turn on it after the source of the pcie clks are stable. - add debug info - add rx_eq of gpr12 on imx6sx - there are random link down issue on imx6sx. It's pcie ep reset issue. solution:reset ep, then retry link can fix it.

* ENGR00319415 pcie: random link down issue after warm-rstRichard Zhu2017-04-05-0/+18
| | | | | | | | | | | | | | | | | | | | | There are about 0.02% percentage on some imx6q/dl/solo hw boards, random pcie link down when warm-reset is used. Make sure to clear the ref_ssp_en bit16 of gpr1 before warm-rst, and set ref_ssp_en after the pcie clks are stable to workaround it. rootcause: * gpr regisers wouldn't be reset by warm-rst, while the ref_ssp_en is required to be reset by pcie. (work-around in u-boot) * ref_ssp_en should be set after pcie clks are stable.
