Note that we have to prepare the following registers' setting in a bootloader (U-Boot) because the registers are protected. Otherwise, data mismatch happened if dmatest with the ipmmu is running. => mw eed01500 0xc0000000; mw eed41500 0xc0000000 [1] https://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git/tag/?h=renesas-drivers-2022-01-11-v5.16 Changes from v2: - Add Reviewed-by tag in patch 1 and 2 (Geert-san, thanks!) - Revise commit description in patch 1. https://lore.kernel.org/all/20220204125653.1194249-1-yoshihiro.shimoda.uh@renesas.com/ Changes from v1: - Add Reviewed-by tag in patch 1.
