From 23058052de302af1e5fcc0c22a8dea97b25d61cd Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Thu, 8 Apr 2021 22:13:10 -0400 Subject: [PATCH] riscv: Enable AI ram on K210 We just need to initialize all the clocks pre-reloc. The clock driver creates a bunch of devices, so we need to increase the pre-reloc malloc arena.
