Since the mx6ulz don't have FEC, it needs to use USB2NET dongle
to connect network. We decouple the CONFIG_FEC_MXC with CONFIG_CMD_NET.
For 6ull, all defconfigs need to enable the CONFIG_FEC_MXC explicitly.Another change is adding ${usb_net_cmd} environment for usb start command
in netboot scripts on 6ulz.Signed-off-by: Ye Li

Add SPL and u-boot support to load images from RAWNAND device when booting
from RAWNAND. The NAND SPL loads the FIT image from nandfit mtdpart at 64MB
offset of NAND. Users need uuu to burn the FIT image, kernel, DTB and rootfs
to all fixed mtdparts.Since NAND SPL needs large BSS and MALLOC size, this patch also moves the MALLOC
pool to DDR, and enable MALLOC_F pool on OCRAM for all malloc before DDR initialization.Signed-off-by: Ye Li

Date: Mon Aug 20 23:35:20 2018 -0700MLK-19263-2 imx8mq_evk: Adjust SPL malloc pool and stack address
Currently the SRAM is allocated to malloc pool due to large malloc
needed by USB SDP. The stack is moved to OCRAM. This causes a
problem when enabling HAB. The HAB authentication needs large
memory on stack, so after ATF image loaded, the stack overwrites
the ATF image in OCRAM and causes authentication failed.This patch moves the malloc pool to DDR and set back stack to
SRAM. So SDP still can run with enough memory on DDR. And the
stack overwrite issue can be fixed by enough memory 24KB left on
SRAM.This change also need to use a early malloc pool by defining the
CONFIG_MALLOC_F_ADDR. And in SPL codes, we have to adjust DDR init
before board_init_r.Signed-off-by: Ye Li

Now fsl_esdhc driver require the index of USDHCx_CLK_ROOT should be

This patch add MXC_XXX_CLK, map to the real defined clock index.

i2c_setup calls force_idle_bus which calls
get_timer if SDA and SCL are not high. On the Pico
baseboard there are level shifters that pull SDA
and SCL high, but the test harness does not have
pull-ups on these lines. Because
board_early_init_f is called before timer_init the
call to get_timer was causing a divide-by-zero
error due to CNTFRQ not being initialized. Moving
the i2c_setup calls to board_init fixes this
issue. power_init_board (which uses I2C to
configure the PMIC) is called after board_init, so
this should be safe.Bug:
Test: PMIC registers are read correctly on both
boards (DEV_ID=0x30 REV_ID=0x11)
Test: iMX7D SOM boots on Pico baseboard
Test: iMX7D SOM boots on test harness
