It is mostly the same SOC except for, at least, one clock tree which is different. This difference is only known by the BSP kernel repository [1]. Currently, the mainline kernel will not hang on rk3288w but it is probably by "chance" because we got an issue on a lower kernel version. According to Rockchip's U-Boot [2], the rk3288w can be detected using the HDMI revision number (= 0x1A) in this version of the SOC. Not to rely on U-Boot about the compatible, the patch 01 will handle the detection of the HDMI version in the rockchip subsystem. Let me know what you think!
