Subject: [PATCH v3 08/11] riscv: Enable AI ram on K210
Date: Thu,  8 Apr 2021 22:13:10 -0400	[thread overview]
Message-ID: <20210409021313.433558-9-seanga2@gmail.com> (raw)
In-Reply-To: <20210409021313.433558-1-seanga2@gmail.com>

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.
