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
[…]
Reviewed-on: http://review.coreboot.org/3209
Please note that AGESA seems to define bigger stack sizes. But
these seem to be too much too.
$ git grep STACK_SIZE src/vendorcode/amd
[…]
src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c:#define BSP_STACK_SIZE 16384

src/vendorcode/amd/agesa/f14/Proc/CPU/Family/0x14/cpuF14CacheDefaults.c: CORE1_STACK_SIZE,
[…]
The following command was used to create the patch.
$ git grep -l STACK_SIZE src/mainboard/ | xargs sed -i '/STACK_SIZE/,+3d'
