[U-Boot] rk3288: 32KB SPL size restriction

[Jagan Teki]

Hi Simon/Philipp or any,

I believe rk3288 has 20KB BootRom and 100KB internal SRAM and current
u-boot can archive the maximum size of u-boot-spl-dtb.bin which the
boot ROM will read is 32KB, do we have any possibility to increase the
SPL size here.

# ./tools/mkimage -n rk3288 -T rksd -d ./spl/u-boot-spl-dtb.bin out.img
Warning: SPL image is too large (size 0x9000) and will not boot
Error: image verification failed

I tried to increase the spl_size from spl_infos (on tools/rkcommon.c)
but not able to boot.

thanks!
