2020-05-18common: Drop linux/delay.h from common headerSimon Glass
Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-01imx8mq: Set ARM core clock directly from ARM PLLPeng Fan
For ARM core clock, there are two input branches, and can select via mux: one from ARM PLL directly, second from CCM A53 clock root. Currently we are using second branch. But IC confirmed the CCM A53 root signoff timing is 1Ghz, so we should switch to input from ARM PLL directly. This patch fixes the CORE SEL slice configuration and switch ARM clock to ARM PLL.

2020-05-01imx8mq: Enable eMMC HS400 and SD UHS mode on EVKYe Li
iMX8MQ EVK board has a eMMC5.0 chip and supports SD3.0, so enable the UHS and HS400 configs to enhance the eMMC/SD access. The change also needs to set usdhc clock to 400Mhz, and add the off-on-delay-us to SD reset pin, otherwise some SD cards will fail to select UHS mode in re-initialization.

2020-01-08imx: imx8mq: handle ESDHC in mxc_get_clockPeng Fan
fsl_esdhc_imx driver will call "mxc_get_clock(MXC_ESDHC_CLK + dev->seq)", however mxc_get_clock wrongly handle MXC_ESDHC_CLK as root clk and cause sd card could not be detected in U-Boot proper, as below: "Loading Environment from MMC... unable to select a mode" Handle MXC_ESDHC_CLK in mxc_get_clock to fix the issue.
