The important one is for Ben - adding Xilinx LL_TEMAC driver and changing Emaclite to NET_MULTI interface + changes in microblaze code to support it. And I decided to remove old Xilinx EMAC driver. It is old driver for old IP and none use it. Ben: Can you please review my net changes? The next big change is removing AtmarkTechno Suzaku board from U-BOOT. Yasushi SHOJI agreed with it some month ago too. Shinya: There is one small patch to qemu website. Please add it to your repo. Thanks for review, Michal ^ permalink raw reply [flat|nested] 12+ messages in thread

Is that appropriate for this architecture (I know nothing about microblaze)? I'd prefer for the device to contain state and device information (an object, if you will), but if there can only be one emaclite on an FPGA, then I guess this is OK. > diff --git a/drivers/net/xilinx_ll_temac.c b/drivers/net/xilinx_ll_temac.c > new file mode 100644 > index 0000000..4b42b06 > --- /dev/null > +++ b/drivers/net/xilinx_ll_temac.c > @@ -0,0 +1,567 @@ > +/* > + * > + * Xilinx xps_ll_temac ethernet driver for u-boot > + * > + * Author: Yoshio Kashiwagi kashiwagi at co-nss.co.jp > + * > + * Copyright (C) 2008 Nissin Systems Co.,Ltd. > + * March 2008 created > + * > + * Copyright (C) 2008 - 2009 Michal Simek <monstr@monstr.eu> > + * June 2008 Microblaze optimalization, FIFO mode support > + * > + * This program is free software; you can redistribute it and/or modify it > + * under the terms of the GNU General Public License as published by the > + * Free Software Foundation; either version 2 of the License, or (at your > + * option) any later version. > + * > + */ > + > +#include <config.h> > +#include <common.h> > +#include <net.h> > +#include <malloc.h> > +#include <asm/processor.h> > +#include <asm/io.h> > + > +#ifdef XILINX_LLTEMAC_FIFO_BASEADDR > +# define FIFO_MODE 1 > +#elif XILINX_LLTEMAC_SDMA_CTRL_BASEADDR > +# define SDMA_MODE 1 > +#else > +# error Unsupported mode > Can you make this error more descriptive please (at least mention which driver) > +#endif > + > +#undef ETH_HALTING > + > +#ifdef SDMA_MODE > +/* XPS_LL_TEMAC SDMA registers definition */ > +# define TX_NXTDESC_PTR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x00) > +# define TX_CURBUF_ADDR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x04) > +# define TX_CURBUF_LENGTH (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x08) > +# define TX_CURDESC_PTR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x0c) > +# define TX_TAILDESC_PTR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x10) > +# define TX_CHNL_CTRL (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x14) > +# define TX_IRQ_REG (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x18) > +# define TX_CHNL_STS (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x1c) > + > +# define RX_NXTDESC_PTR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x20) > +# define RX_CURBUF_ADDR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x24) > +# define RX_CURBUF_LENGTH (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x28) > +# define RX_CURDESC_PTR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x2c) > +# define RX_TAILDESC_PTR (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x30) > +# define RX_CHNL_CTRL (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x34) > +# define RX_IRQ_REG (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x38) > +# define RX_CHNL_STS (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x3c) > + > +# define DMA_CONTROL_REG (XILINX_LLTEMAC_SDMA_CTRL_BASEADDR + 0x40) > +#endif > + > +/* XPS_LL_TEMAC direct registers definition */ > +#define TEMAC_RAF0 (XILINX_LLTEMAC_BASEADDR + 0x00) > +#define TEMAC_TPF0 (XILINX_LLTEMAC_BASEADDR + 0x04) > +#define TEMAC_IFGP0 (XILINX_LLTEMAC_BASEADDR + 0x08) > +#define TEMAC_IS0 (XILINX_LLTEMAC_BASEADDR + 0x0c) > +#define TEMAC_IP0 (XILINX_LLTEMAC_BASEADDR + 0x10) > +#define TEMAC_IE0 (XILINX_LLTEMAC_BASEADDR + 0x14) > + > +#define TEMAC_MSW0 (XILINX_LLTEMAC_BASEADDR + 0x20) > +#define TEMAC_LSW0 (XILINX_LLTEMAC_BASEADDR + 0x24) > +#define TEMAC_CTL0 (XILINX_LLTEMAC_BASEADDR + 0x28) > +#define TEMAC_RDY0 (XILINX_LLTEMAC_BASEADDR + 0x2c) > + > Please put these registers in a struct and access it using io accessors (writel, writew etc.).
