* wandboard: Make Ethernet functional againFabio Estevam2016-11-06-0/+33
| | | | | | | | | | | | | | | | | | Since commit ce412b79e7255770 ("drivers: net: phy: atheros: add separate config for AR8031") ethernet does not work on mx6sabresd. This commit correctly assigns ar8031_config() as the configuration function for AR8031 in the same way as done in the Linux kernel. However, on wandboard design we need some additional configuration, such as enabling the 125 MHz AR8031 output that needs to be done in the board file. This also aligns with the same method that the kernel performs the AR8031 fixup in arch/arm/mach-imx/mach-imx6q.c.

* wandboard: Fix hang when going into low frequencyFabio Estevam2016-10-04-3/+3
| | | | | | | | | | | | | | A kernel hang is observed when running wandboard 3.14 kernel and going to the lowest operational point of cpufreq: # ifconfig eth0 down # echo 1 > /sys/class/graphics/fb0/blank The problem is caused by incorrect setting of the REFR field of register MDREF. Setting it to 4 refresh commands per refresh cycle fixes the hang. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>

* mx6: ddr: Allow changing REFSEL and REFR fieldsFabio Estevam2016-09-06-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* wandboard: Simplify the Ethernet PHY configurationFabio Estevam2016-01-07-34/+2
| | | | | | | | | | | | | | | | | As per the AR8031 datasheet: "For a reliable power on reset, suggest to keep asserting the reset low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms requirement is satisfied." So do as suggested and also add a 100us delay after deasserting the reset line to guarantee that the PHY ID can be read correctly and the Atheros 8031 PHY driver can be loaded automatically. This results in a simpler code. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

Note that SPI_PAD_CTRL was defined by several boards with a pull value, but without PKE or PUE, which means that no pull was actually enabled in the pad. This might be a bug in those boards, but this patch does not change the behavior, so it just removes the meaningless pull value from those definitions.

| | | | | | | | | | | | | | | | | | Maximum bus width supported by some i.MX6 boards is not 8bit like others. In case where both host controller and card support 8bit transfers, they agree to communicate on 8bit interface while some boards support only 4bit interface. Due to this reason the mmc 8bit default mode fails on these boards. To rectify this, define maximum bus width supported by these boards (4bit). If max_bus_width is not defined, it is 0 by default and 8bit width support will be enabled in host capabilities otherwise host capabilities are modified accordingly. It is tested with a MMCplus card.
