[Buildroot] [PATCH v2 3/3] package/freescale-imx/imx-m4-firmware: add support for i.MX7ULP

Fabrice Goucem fabrice.goucem at nxp.com
Wed Oct 30 13:40:15 UTC 2019 

Create new flag BR2_PACKAGE_FREESCALE_IMX_PLATFORM_IMX7ULP to
differentiate i.MX7ULP from i.MX7D which has different Cortex-M4
firmware.

Signed-off-by: Fabrice Goucem <fabrice.goucem at nxp.com>

Changes v1 -> v2:
  - Split i.MX7ULP support into two commits:
	new defconfig and m4 support (suggested by Fabio Estevam)
