      Use explicit-width data types in AAPCS parameter structs · 9352be88
      Julius Werner authored 
      

It's not a good idea to use u_register_t for the members of
aapcs64_params_t and aapcs32_params_t, since the width of that type
always depends on the current execution environment. This would cause
problems if e.g. we used this structure to set up the entry point of an
AArch32 program from within an AArch64 program. (It doesn't seem like
any code is doing that today, but it's probably still a good idea to
write this defensively. Also, it helps with my next patch.)

      plat/rockchip: Switch to use new common BL aux parameter library · c1185ffd
      Julius Werner authored 
      

This patch changes all Rockchip platforms to use the new common BL aux
parameter helpers. Since the parameter space is now cleanly split in
generic and vendor-specific parameters and the COREBOOT_TABLE
parameter is now generic, the parameter type number for that parameter
has to change. Since it only affects coreboot which always builds TF as
a submodule and includes its headers directly to get these constants,
this should not cause any issues. In general, after this point, we
should avoid changing already assigned parameter type numbers whenever
possible.

      Introduce lightweight BL platform parameter library · b852d229
      Julius Werner authored 
      

This patch adds some common helper code to support a lightweight
platform parameter passing framework between BLs that has already been
used on Rockchip platforms but is more widely useful to others as well.
It can be used as an implementation for the SoC firmware configuration
file mentioned in the docs, and is primarily intended for platforms
that only require a handful of values to be passed and want to get by
without a libfdt dependency. Parameters are stored in a linked list and
the parameter space is split in generic and vendor-specific parameter
types. Generic types will be handled by this code whereas
vendor-specific types have to be handled by a vendor-specific handler
function that gets passed in.
