Felix - Can you please add the appropriate BUG# here? BUG=b:????
Done
File src/arch/x86/early_ram.ld:
Patch Set #22, Line 23: . = CONFIG_X86_RESET_VECTOR - ARCH_POINTER_ALIGN_SIZE - _STACK_SIZE - _CONSOLE_SIZE - _TIMESTAMPS_SIZE - _FMAP_SIZE;
Increasing C_ENV_BOOTBLOCK_SIZE fixes the overlaps. I'll push a CL that clarifies some of this.
I refactored the patch a bit.
I moved the stack out of .earlyram.data and renamed .earlyram.data to .persistent since this data persists across stages.
I also added an assert that will tell if you if the earlyram data overlaps with the program data.
Building on a trembyle I get the following:

I did have to increase the C_ENV_BOOTBLOCK_SIZE on my platform so it would compile.
