Recent commit4a603eb
("platform: kendryte/k210: Set per-HART stack size to 8KB") forgot to update ariane-fpga codes, and the following commit678c3c3
("include: sbi_scratch: Set per-HART scratch size to 4KB") changed the per-HART scratch size to 4KB, which potentially breaks ariane-fpga platform. This patch set per-HART stack size of ariane-fpga to 8KB for consistency. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Anup Patel <anup.patel@wdc.com>
