This ram bank was previously unusable because PLL1 was not started correctly.
This series fixes that bug, and allows U-Boot to relocate into the AI ram. This
provides an extra 2M of space in which to load payloads.
Sean Anderson (10):
clk: k210: Fix PLLs not being enabled
clk: Add support for the k210 clock driver pre-relocation
riscv: Enable some devices pre-relocation
lib: fdt: Add fdtdec_setup_mem_size_base_highest
test: Add a test for fdtdec_setup_mem_size_base et al.
ram: Add driver for K210 SRAM
ram: sifive: Default to y only if compiling for fu540
riscv: Probe ram in dram_init
riscv: Enable AI ram on K210
riscv: Don't reserve AI ram in k210 dts
