2010-11-30add Xilinx_abort_fn to Xilinx_Spartan3_Slave_Serial_fnsWolfgang Wegner
Currently the hardware was left in an undefined state in case Spartan3 serial load failed. This patch adds Xilinx_abort_fn to give the board a possibility to clean up in this case. Signed-off-by: Wolfgang Wegner <w.wegner@astro-kom.de>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

2010-10-18FPGA: fix support for non-Lattice devicesWolfgang Denk
Commit 3b8ac464 "FPGA: add support for downloading Lattice bitstream" added support for Lattice devices, but failed to add #ifdef's that are needed when building for non-Lattice devices, which results in build failures like these: Configuring for GEN860T board... drivers/fpga/libfpga.a(fpga.o): In function `fpga_dev_info': /home/wd/git/u-boot/work/drivers/fpga/fpga.c:145: undefined reference to `lattice_info' drivers/fpga/libfpga.a(fpga.o): In function `fpga_dump': /home/wd/git/u-boot/work/drivers/fpga/fpga.c:269: undefined reference to `lattice_dump' drivers/fpga/libfpga.a(fpga.o): In function `fpga_load': /home/wd/git/u-boot/work/drivers/fpga/fpga.c:233: undefined reference to `lattice_load' make: *** [u-boot] Error 1 Add the missing code.

2010-10-13FPGA: add support for downloading Lattice bitstreamStefano Babic
The patch adds support to load a Lattice's bitstream image (called VME file) into a Lattice FPGA. The code containing the state machine delivered as part of Lattice's ispVMtools is integrated. The FPGA is programmed using the JTAG interface. The board maintainer must provide accessors to drive the JTAG signals TCK, TMS, TDI and to get the value of the input signal TDO.

2010-03-24add block write function to spartan3 slave serial loadWolfgang Wegner
Using seperate function calls for each bit-bang of slave serial load can be painfully slow. This patch adds the possibility to supply a block write function that loads the complete block of data in one call (like it can already be done with Altera FPGAs). On an MCF5373L (240 MHz) loading an XC3S4000 this reduces the load time from around 15 seconds to around 3 seconds Signed-off-by: Wolfgang Wegner <w.wegner at astro-kom.de>
2009-10-03fpga: Remove relocation fixupsPeter Tyser
PPC boards are the only users of the current FPGA code which is littered with manual relocation fixups. Now that proper relocation is supported for PPC boards, remove FPGA manual relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-02-21fpga: Fix Spartan III FPGA bootingMatthias Fuchs
This patch does some minor fixing of the Xilinx Spartan III FPGA boot code: - Fixed call order of post configuration callback and success message printing (result of copy-paste?) - remove obsolete comment - minor coding style cleanup Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com>
