Hello,
This patchset adds initial board support for iMX8QXP AI_ML board
from Einfochips. This board is one of the Consumer Edition and AI
boards of the 96Boards family.
This initial supports contains following peripherals which are tested and
known to work:
1. Debug serial via UART2
2. SD card
3. Ethernet
Thanks,
Mani
Note: This patchset depends on the below cleanup patches submitted:
[U-Boot,1/2] arm: imx8: factor out uart init code
[U-Boot,2/2] arm: imx8: don't duplicate build_info()
Changes in v2:
* Rebased the patches on top of following patches:
[U-Boot,1/2] arm: imx8: factor out uart init code
[U-Boot,2/2] arm: imx8: don't duplicate build_info()

This board is one of the 96Boards Consumer Edition and AI boards of the 96Boards family based on i.MXQXP SoC from NXP/Freescale. This initial supports contains following peripherals which are tested and known to work: 1. Debug serial via UART2 2. SD card 3. Ethernet More information about this board can be found in arrow website: https://www.arrow.com/en/products/imx8-ai-ml/arrow-development-tools Signed-off-by: Manivannan Sadhasivam
