[U-Boot] [PATCH 1/3] mx6sabresd: Do not use DM with SPL
With CONFIG_SPL_DM enabled the board does not boot:
U-Boot SPL 2019.07-rc2 (May 16 2019 - 14:28:55 -0300) Trying to boot from MMC1 spl: could not find mmc device 0. error: -19 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
Remove such option, so that we can boot the board.
Signed-off-by: Fabio Estevam festevam@gmail.com --- Hi,
If someone wants to fix the boot issue with CONFIG_SPL_DM=y, please submit a patch, as I don't know what is the proper fix here.
Also, there is also the need for applying Peng's fix for the framebuffer hang: https://lists.denx.de/pipermail/u-boot/2019-April/366424.html
Thanks

With the conversion to DM we should select the pinctrl driver.

After the conversion to DM there is no need to have mmc initialization code inside U-Boot proper.
Remove the unneeded code.
