The Rockchip-released ATF for the Firefly apparently (i.e. Kever
reported this) does not tolerate a FDT being passed as the platform
parameter and will run into a hard stop.
To work around this limitation in the ATF parameter handling, we
enable SPL_ATF_NO_PLATFORM_PARAM (which will force passing NULL for
the platform parameters).
Note that this only affects this platform, as the ATF releases for the
RK3368 and RK3399 have always either ignored the platform parameter
(i.e. before the FDT-based parameters were supported) or support
receiving a pointer to a FDT.
Upstream ATF of Rockchip platform support a vendor defined
" structbl31_plat_param *bl2_param", will add support for FDT later,
see params_early_setup() in
https://github.com/ARM-software/arm-trusted-firmware/blob/master/plat/rockchip/common/params_setup.c
What exactly do you want to configure in ATF from FDT?
Do you have any code somewhere to take a look?
Sorry, no code for it now.
I think we will use and append reserved memory for it.
SPL set available memory region, and ATF reserved for its TA so that
U-Boot won't use it,
we are using the hard code for this feature now.
