I'd leave it as is. Issues that you brought up can be fixed as needed. I think with Furquan's SPI changes a lot of the flash part drivers are fixed to not use globals. That just leaves the spi flash controller drivers. It looks like the 'flashes' variable in spi_flash.c should be const, but I doubt that's what you are hitting.
Ok, I'll leave it as is. The issue I got previously were indeed all the global vars in the spi drivers which got fixed by Furquan's changes. But compiling for broadwell still fails because of a lack of timer_monotonic_get, and when I add monotonic_timer.c to the Makefile for romstage, it complains about mono_count global variable, which I remove and replace the timer_monotonic_get code in broadwell with the implementation in skylake (which doesn't need a global var), then I get issues with the spi_ctrlr_bus_map and spi_ctrlr_bus_map_count in spi-generic.c. After I removed those and commented out the spi_setup_slave, it worked, no more issues. I didn't test it though.
I'm still baffled as to why I only get the global vars warning (and missing timer_monotonic_get) in romstage but not in bootblock.

It seems to me that this sequence could be used for both branches of the co
I've made both conditions the same. I don't understand what you meant about it being a pain because of :=
