[U-Boot] [RFC PATCH v2 00/18] WIP Add support for i.MXRT family

[Giulio Benetti]

Hello everybody,

following:
https://lists.denx.de/pipermail/u-boot/2019-October/388853.html

I send a new patchset where WIP means that patch is still not finished but if
possible I would like to have a feedback.
This patchset provides:
- soc family entry
- pinctrl driver
- serial driver tweaking
- sdram controller driver
- imxrt1050-evk board basic support
- clock setup using CCF
- addings to pllv3 driver
- some little improvement for DM_CLK in drivers

I still can't have usdhc completely working since it reads zeroes starting from
sector 256(0x100).
While LCDIF is in WIP but almost ready.

Thanks in advance for eventually reviewing these patches.

Best regards
