The 'xtfpga' board is actually a set of FPGA evaluation boards that can be configured to run an Xtensa processor.
- Avnet Xilinx LX60 - Avnet Xilinx LX110 - Avnet Xilinx LX200 - Xilinx ML605 - Xilinx KC705
These boards share the same components (open-ethernet, ns16550 serial, lcd display, flash, etc.).

This mapping is implemented in the FPGA bitstream + and cannot be disabled by software, therefore DIP switch 8 is no + available for application use. Note DIP switch 7 is reserved by + Tensilica for future possible hardware use. + + Mapping to SRAM allows U-Boot to be debugged with an OCD/JTAG + tool such as the Xtensa OCD Daemon connected via a suppored probe. + See the tools documentation for supported probes and how to + connect them. Be aware that the board has only 128 KB of SRAM, + therefore U-Boot must fit within this space to debug an image + intended for the Flash. This issues is discussed in a separate + section toward the end. + + Mapping to flash allows U-Boot to start on reset, provided it + has been programmed into the first two 64 KB sectors of the Flash. + + The Flash is always mapped at a device (memory mapped I/O) address + (the address is board specific and is expressed as CFG_FLASH_BASE). + The device address is used by U-Boot to program the flash, and may + be used to specify an application to run or U-Boot image to boot. + +Default MAC Address (DIP switches 1-6): + + When the board is first powered on, or after the environment has + been reinitialized, the ethernet MAC address receives a default + value whose least significant 6 bits come from DIP switches 1-6. + The default is 00:50:C2:13:6F:xx where xx ranges from 0..3F + according to the DIP switches, where "on"==1 and "off"==0, and + switch 1 is the least-significant bit. + + After initial startup, the MAC address is stored in the U-Boot + environment variable 'ethaddr'. The user may change this to any + other address with the "setenv" comamnd. After the environment + has been saved to Flash by the "saveenv" command, this will be + used and the DIP switches no longer consulted. DIP swithes 1-6 + may then be used for application purposes. + +The KC705 board contains 4-way DIP switch, way 1 is the boot mapping +switch and ways 2-4 control the low three bits of the MAC address. + + +Limitation of SDRAM Size for OCD Debugging on the LX60 +------------------------------------------------------ + +The XT-AV60 board has only 128 KB of SDRAM that can be mapped +to the system ROM address space for debugging a ROM image under +OCD/JTAG. This limits the useful size of U-Boot to 128 KB (0x20000) +or the first 2 sectors of the flash. + +This can pose a problem if all the sources are compiled with -O0 +for debugging. The code size is then too large, in which case it +would be necessary to temporarily alter the linker script to place +the load addresses (LMA) in the RAM (VMA) so that OCD loads U-Boot +directly there and does not unpack. In practice this is not really +necessary as long as only a limited set of sources need to be +debugged, because the image can still fit into the 128 KB SRAM. + +The recommended procedure for debugging is to first build U-Boot +with the default optimization level (-Os), and then touch and +rebuild incrementally with -O0 so that only the touched sources +are recompiled with -O0. To build with -O0, pass it in the KCFLAGS +variable to make. + +Because this problem is easy to fall into and difficult to debug +if one doesn't expect it, the linker script provides a link-time +check and fatal error message if the image size exceeds 128 KB. + diff --git a/board/cadence/xtfpga/xtfpga.c b/board/cadence/xtfpga/xtfpga.c new file mode 100644 index 0000000..5899aa6 --- /dev/null +++ b/board/cadence/xtfpga/xtfpga.c @@ -0,0 +1,115 @@ +/* + * (C) Copyright 2007 - 2013 Tensilica Inc. + * (C) Copyright 2014 - 2016 Cadence Design Systems Inc. + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#include <common.h> +#include <command.h> +#include <dm/platdata.h> +#include <dm/platform_data/net_ethoc.h> +#include <linux/ctype.h> +#include <linux/string.h> +#include <linux/stringify.h> +#include <asm/global_data.h> + +DECLARE_GLOBAL_DATA_PTR; + +/* + * Check board idendity. + * (Print information about the board to stdout.) + */ + + +#if defined(CONFIG_XTFPGA_LX60) +const char *board = "XT_AV60"; +const char *description = "Avnet Xilinx LX60 FPGA Evaluation Board / "; +#elif defined(CONFIG_XTFPGA_LX110) +const char *board = "XT_AV110"; +const char *description = "Avnet Xilinx Virtex-5 LX110 Evaluation Kit / "; +#elif defined(CONFIG_XTFPGA_LX200) +const char *board = "XT_AV200"; +const char *description = "Avnet Xilinx Virtex-4 LX200 Evaluation Kit / "; +#elif defined(CONFIG_XTFPGA_ML605) +const char *board = "XT_ML605"; +const char *description = "Xilinx Virtex-6 FPGA ML605 Evaluation Kit / "; +#elif defined(CONFIG_XTFPGA_KC705) +const char *board = "XT_KC705"; +const char *description = "Xilinx Kintex-7 FPGA KC705 Evaluation Kit / "; +#else +const char *board = "<unknown>"; +const char *description = ""; +#endif + +int checkboard(void) +{ + printf("Board: %s: %sTensilica bitstream\n", board, description); + return 0; +} + +void dram_init_banksize(void) +{ + gd->bd->bi_memstart = PHYSADDR(CONFIG_SYS_SDRAM_BASE); + gd->bd->bi_memsize = CONFIG_SYS_SDRAM_SIZE; +} + +int board_postclk_init(void) +{ + /* + * Obtain CPU clock frequency from board and cache in global + * data structure (Hz).
