[U-Boot] [PATCH v2] board: ge: bx50v3: Pass video bootargs for b850v3

[Akshay Bhat]

From: Ken Lin <ken.lin at advantech.com.tw>

Due to clock source restrictions on i.MX6, certain pixel clock rates can
not be supported. Hence default the resolution/frame rate during boot to a
supported value by passing video bootargs 1024x768 at 60 for
HDMI (Display Port1) and LVDS (Display Port2) on B850v3.

v1 -> v2:
Rename CONFIG_BOOTARGS_EXTRA to BX50V3_BOOTARGS_EXTRA since CONFIG_* is
reserved for defines added via Kconfig
