[Buildroot] [PATCH] configs: add Freescale i.MX6 SoloX Sabre SD support

Tue May 26 14:42:22 UTC 2015

From: Vincent Stehlé <vincent.stehle at laposte.net>

The i.MX6 SoloX SABRE board for smart devices is Freescale's reference design
board based on the heterogeneous ARM Cortex-A9 + Cortex-M4 i.MX6 SoloX
applications processor.

This defconfig is inspired from previous freescale_imx6*sabresd_defconfig, and
is based on Freescale "official" git repo on git.freescale.com and SW release
3.10.53_1.1.0_ga.

Hi,

This is a proposed defconfig for i.MX6 SoloX.

Because the i.MX6 SoloX is not supported with the Freescale release 3.10.17
currently in use by i.MX6 defconfigs in buildroot, and because patches to
"bump" other i.MX6 boards to release 3.10.53 have been kindly submitted by Gary
[1], this defconfig is based on release 3.10.53 for consistency.

To compile properly, this defconfig depends on a "refresh" of an u-boot patch,
posted earlier [2].

Best regards,

V.
