configs/amarula_vyasa_rk3288: adjust U-Boot config to boot larger kernel image
Default value of CONFIG_SYS_BOOTM_LEN in u-boot causes board reset for large uImage files, so add u-boot patch to increase the maximum kernel image size. Signed-off-by: Shyam Saini <shyam.saini@amarulasolutions.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

+Subject: [PATCH] include: configs: Increase CONFIG_SYS_BOOTM_LEN to 16MB
+
+The default value of CONFIG_SYS_BOOTM_LEN is 0x800000 i.e, 8MB which
+causes board reset because of larger uImage size.
+
+Error log snippet:
+ Booting using the fdt blob at 0x1f00000
+ Loading Kernel Image ... Image too large: increase CONFIG_SYS_BOOTM_LEN
+Must RESET board to recover
+resetting ...
