Re: [PATCH] sunxi-nand: fix the PIO instead of DMA implementation

Hi Miquel, hi Maxime, could you probably run a test on a newer Allwinner SOC - like e.g. SUNI8, SUNI9, SUNI50 or newer, since I can test it on a SUNI7 (A20) board only? The only aspect that makes me wonder is, that it did work on your hardware before at all. Maybe this is, since that NFC_CTL_RAM

[PATCH] sunxi-nand: fix the PIO instead of DMA implementation
