[U-Boot] [PATCH 4/7] EXYNOS: support EXYNOS framebuffer and FIMD display drivers.

[Anatolij Gustschin]

Hi,

Thank you for reworking this patch. It is mostly okay now and I can compile
the drivers, :-). Only two minor issues, please see comments below.

The s6e8ax0 driver is added in another patch, so please move
COBJS-$(CONFIG_S6E8AX0) += s6e8ax0.o to the patch which adds s6e8ax0
driver.

Now I can compile the driver and see the following warning:
exynos_fb.c: In function 'exynos_lcd_init_mem':
exynos_fb.c:52:30: warning: variable 'palette_mem_size' set but not used
[-Wunused-but-set-variable]

Please drop 'palette_mem_size' local variable here.

Thanks,
