[meta-rockchip] [PATCH v3] rk3288: use u-boot.img as bootloader image

[meta-rockchip] [PATCH v3] rk3288: use u-boot.img as bootloader image

[Peter Shkenev]

Currently, u-boot.bin is used for supported rk3288-based boards. But on
some boards, such as tinker-board, it can not be loaded, since
u-boot.bin is raw and those boards have raw image support
(CONFIG_SPL_RAW_IMAGE_SUPPORT) disabled in favour of FIT images.

Use u-boot.img which is FIT when FIT support is enabled, and raw
otherwise.

Also add a note that u-boot.itb should be used if one wantes to utilize
OP-TEE.

My build testing shows that this patch fails for the rock2-square
MACHINE. Are others seeing this as well? In the v1 patch Quentin noticed
this and mentioned building for all rk3288 devices, was this tested?

Actually, never mind, the fix is so small and obvious, I'll just roll it
into the patch and commit it.

Applied to meta-rockchip, master branch.
Thanks!

(Probably should have used ${UBOOT_SUFFIX} for the fixup :) )

Do you have a Rock2 Square by any chance? I'm wondering if we cannot 
migrate it to use wic instead of rockchip-gpt-img for generating the 
final flashable image? But I don't own the board so it makes it a bit 
hard to test patches.

Cheers,
Quentin
