asrock/e350m1: reduce default stack size
The stack used on the ASRock E350M1 is significantly less than what we currently set (64k per core). In fact, we use about half of the default stack size (4k) on core 0 and even less on non BSP cores [1]: $ grep stack coreboot_without_patch_but_monotonic_timer.log CPU1: stack_base 002a0000, stack_end 002afff8 CPU1: stack: 002a0000 - 002b0000, lowest used address 002afda8, stack used: 600 bytes CPU0: stack: 002b0000 - 002c0000, lowest used address 002bf75c, stack used: 2212 bytes Removing the Kconfig variable STACK_SIZE to use the default results in the following numbers of stack usage. $ grep stack coreboot_with_patch.log CPU1: stack_base 00287000, stack_end 00287ff8 CPU1: stack: 00287000 - 00288000, lowest used address 00287da8, stack used: 600 bytes CPU0: stack: 00288000 - 00289000, lowest used address 0028875c, stack used: 2212 bytes [1] http://review.coreboot.org/#/c/3154/ (comment May 2 10:21 AM) Change-Id: Ibdb2102c86094fce3787e3b5a162ca8423de205c Signed-off-by: Stefan Reinauer <reinauer@google.com> Tested-by: Paul Menzel <paulepanter@users.sourceforge.net> Signed-off-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-on: http://review.coreboot.org/3209 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
