[U-Boot] [PATCH v2 0/3] board/seco: Add mx6q-uq7 basic board support

[U-Boot] [PATCH v2 0/3] board/seco: Add mx6q-uq7 basic board support

[Boris Brezillon]

Hello,

This series adds a preliminary support for SECO's iMX6 based boards.

The first 2 patches add generic support for MX6 SoCs, avoiding the need
to define SoC variant and imximage.cfg file patch in the deprecated
SYS_EXTRA_OPTIONS Kconfig option.

The last patch adds basic support for the mx6q/uq7 SECO board, and a
sane Kconfig skeleton for other SoC (Q, DL and S) and board (uQ7, Q7
and uSBC) variants.

Best Regards,

Boris

Changes since v1:
- fix board Makefile
- add a MAINTAINERS file
- fix coding style issues
- add error messages where appropriate

[U-Boot] [PATCH v2 1/3] ARM: mx6: move to a standard arch/board approach

[Boris Brezillon]

Freescale boards are currently all defined in arch/arm/Kconfig, which
makes them hard to detect.
Moreover the MX6 SoC variant (Q, D, DL, S, SL) selection is currently
done via the SYS_EXTRA_OPTIONS option which marked as deprecated.

Move to a more standard way to select sub-architecture and board by
creating a Kconfig under arch/arm/cpu/armv7/mx6 and a new ARCH_MX6
option.

Existing MX6 board definitions should be moved in this new Kconfig in
choice menu, and new boards should be directly declared in this menu.

[U-Boot] [PATCH v2 2/3] ARM: iMX: define an IMX_CONFIG Kconfig option

[Boris Brezillon]

IMX_CONFIG is currently passed via the SYS_EXTRA_OPTIONS which is marked
as deprecated.

Add a new Kconfig file under arch/arm/imx-common and define the
IMX_CONFIG Kconfig in there.

Each board is supposed to provide a default value pointing to the
appropriate imximage.cfg file.

[U-Boot] [PATCH v2 3/3] board/seco: Add mx6q-uq7 basic board support

[Boris Brezillon]

Add basic SECO MX6Q/uQ7 board support (Ethernet, UART, SD are supported).
It also adds a Kconfig skeleton to later add more SECO board (supporting
SoC and board variants).

As this adds the board definitions, are you going to also send a patch
to the existing boards?

board maintainers.

Note that I'm not breaking anything (the old boards definition are
still working).
