mx6ul_14x14_ev: Enable the CCGR clocks earlier

2016-09-06T16:22:48Z

To be in the safe side we need to enable the CCGR clocks prior to calling arch_cpu_init(). Inspired by Tim Harvey's commit d783c2744f9 ("imx: ventana: fix boot to SD"). Signed-off-by: Fabio Estevam Reviewed-by: Eric Nelson Tested-by: Eric Nelson

mx6ul_14x14_evk: Pass refsel and refr fields to avoid hang

2016-09-06T16:22:48Z

When running a NXP 4.1 kernel with U-Boot mainline on a mx6ul-evk, we observe a hang when going into the lowest operational point of cpufreq. This hang issue does not happen on the NXP U-Boot version. After comparing the SPL DDR initialization against the DCD table from NXP U-Boot, the key difference that causes the hang is the MDREF register setting: DATA 4 0x021B0020 0x00000800 ,which means: REF_SEL = 0 --> Periodic refresh cycle: 64kHz REFR = 1 ---> Refresh Rate - 2 refreshes So adjust the MDREF initialization for mx6ul_evk accordingly to fix the kernel hang issue at low bus frequency.

mx6: ddr: Allow changing REFSEL and REFR fields

2016-09-06T16:22:48Z

Currently MX6 SPL DDR initialization hardcodes the REF_SEL and REFR fields of the MDREF register as 1 and 7, respectively for DDR3 and 0 and 3 for LPDDR2. Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed. Keep all the mx6 SPL users in their current REF_SEL and REFR values, so no functional changes for the existing users. Signed-off-by: Fabio Estevam Reviewed-by: Eric Nelson
