      rockchip: px30: cleanup securing of ddr regions · f55ef85e
      Heiko Stuebner authored 
      

So far the px30-related ddr security was loading data for regions to secure
from a pre-specified memory location and also setting region0 to secure
the first megabyte of memory in hard-coded setting (top=0, end=0, meaning
1MB).

To make things more explicit and easier to read add a function doing
the settings for specified memory areas, like other socs have and also
add an assert to make sure any descriptor read from memory does not
overlap the TZRAM security in region0 and TEE security in region1.

      rockchip: px30: move secure init to separate file · d2483afa
      Heiko Stuebner authored 
      

Similar to others like rk3399 and rk3288 move the secure init to a
separate file to unclutter the soc init a bit.

      rockchip: really use base+size for secure ddr regions · 7f0b2e78
      Heiko Stuebner authored 
      

The calls to secure ddr regions on rk3288 and rk3399 use parameters of
base and size - as it custom for specifying memory regions, but the
functions themself expect start and endpoints of the area.

This only works by chance for the TZRAM, as it starts a 0x0 and therefore
its end location is the same as its size.

To not fall into a trap later on adapt the functions to really take
base+size parameters.

      rockchip: bring TZRAM_SIZE values in line · c6ee020e
      Heiko Stuebner authored 
      

The agreed upon division of early boot locations is 0x40000 for bl31
to leave enough room for u-boot-spl and 0x100000 for bl33 (u-boot).

rk3288 and rk3399 already correctly secure the ddr up to the 1MB boundary
so pull the other platforms along to also give the Rockchip TF-A enough
room to comfortably live in.

      rockchip: Prevent macro expansion in paths · 39a97dce
      Joshua Watt authored 
      

Instead of stringizing the paths to binary files, add them as string
defines on the command line (e.g. -DFOO=\"BAR\" instead of -DFOO=BAR).
This prevents macros from being expanded inside the string value itself.
For example, -DFOO=/path/with-linux-in-it would have been expanded to
"/path/with-1-in-it" because `linux=1` is one of the standard GCC
defines.
