Changing the subject line since this thread isn't really about toolchains any more.
The problem I'm having with the SPL build is that a single entry in boards.cfg can have exactly one architecture and CPU model. So
But you can define any tye of CONFIG_ settings, both in boards.cfg and in your board config file.
there's no easy way to have the SPL build compile from arm720t and the non SPL build compile from armv7. So I either have to have two
What would prevent you from extending the Makefiles to set build options depending on CONFIG_ settings from your board configuration?
What I really need is the ability to change "CPU" between SPL and non SPL build. This gets set too early for the board config file to override. What I really need is something like this in the generated include/config.mk:
ARCH = arm ifeq ($(CONFIG_SPL_BUILD),y) CPU = arm720t else CPU = armv7 endif BOARD = seaboard VENDOR = nvidia SOC = tegra2
As an experiment I tried this, and it seems to do what I want. I don't see a clean way to do this without it being a hack or really intrusive though.
