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
