| * arm: zynqmp: add boot source supportMichael Riesch2021-10-041-0/+86
| | | | | | | | | | | | | | | | | | | | The ZynqMP reports the mode pins sampled at POR via the register ZYNQMP_CRL_APB_BOOT_MODE_USER. This commit adds a function that reads the register and populates the boot source.

| * ARM: zynqmp: use std_file_update as update handlerMichael Tretter2021-08-231-37/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The update handler for zynqmp copies the boot.bin file into an existing fat partition. There is already a better implementation by bbu_register_std_file_update(). Drop the custom implementation. Keep the previous functions with its signature to have an obvious common update handler for all ZynqMP boards.

| * firmware: zynqmp-fpga: do not use DMA coherent memory for bitstreamMichael Tretter2021-08-231-8/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Trying to do unaligned access of coherent memory on AArch64 will lead to an abort. This can happen when the FPGA loader copies the bitstream to the temporary buffer for the transfer to the FPGA. Convert the driver to use regular memory for the temporary buffer to prevent the issue.

| * firmware: zynqmp-fpga: avoid additional buffer for size argumentMichael Tretter2021-08-231-21/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two different APIs for loading an FPGA via the pmu-fw as indicated by the ZYNQMP_PM_FEATURE_SIZE_NOT_NEEDED feature flag. The pmu-fw expects as second argument either the size of the bitstream or a pointer to the size of the bitstream. The driver allocates a separate buffer for the size, which results in the allocation of a 4k page for storing a 32 bit value. Allocate some more memory for the bitstream and append the size of the bitstream at the end of the bitstream to avoid the additional memory allocation. Add a comment to explain the surprising size of the allocation.

| * | scripts: allow building USB loader tools for target as wellAhmad Fatoum2021-10-0213-2/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently build the USB loader tools only for the host (build) system, but it can be useful to cross compile them as well for the target. We already have some target tools, but support for those is easier, because they don't link against libraries. We use pkg-config to get cc and ld flags, but we always assume that pkg-config is for the host system and there is no well-defined way to request pkg-config for the target system. Support this by introducing a new CROSS_PKG_CONFIG. This will be consulted only for target tools and default to $(CROSS_COMPILE)pkgconfig. Users can override it as necessary, for example, with Yocto, pkg-config will be for the cross environment, so target tools can now be built with: export ARCH=sandbox CROSS_COMPILE=aarch64-linux-gnu- export CROSS_PKG_CONFIG=pkg-config scripts make targettools_defconfig make scripts Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20210917174127.23345-4-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * | scripts: omap3-usb-loader: make proper use of pkg-config --cflagsAhmad Fatoum2021-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pkg-config --cflags libusb-1.0 should ensure <libusb.h> would be found. Command's output is used to compile omap3-usb-loader.c, but because the file does #include <libusb-1.0/libusb.h>, it will probably not find the header in the directory added to search path by pkg-config and depend on other directories in the search path. Fix this. We already expect users to have proper pkg-config files, so linking works, so it's not too much to ask to expect the pkg-config file that should already exist to yield proper --cflags as well.

LiteEth is part of LiteX libraries whose aims are to lower entry level of complex FPGA cores by providing simple, elegant and efficient implementations of components used in today's SoC such as Ethernet, SATA, PCIe, SDRAM Controller... Using Migen to describe the HDL allows the core to be highly and easily configurable. LiteEth can be used as LiteX library or can be integrated with your standard design flow by generating the verilog rtl that you will use as a standard core.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Printing the framebuffer base is unnecessary because it's already contained in the dev_printf prefix. Make the message shorter and only print it on success.

This wasn't done in the simplefb driver so far, fix this. This also lets us drop some initialization of the fb_info, because it can be calculated from the mode. The very verbose mode info print can be dropped as well, because it's now available in devinfo.

This allows the removal of the usb composite driver from dfu.c As the dfu command is blocking the command slice must be released while the dfu gadget is running in order to do operations on the file system. The usb_dfu_register() function is replaced with usb_dfu_detached() for the dfu command to return a different value depending on if it has been interrupted with CTRL-C or if the gadget has been detached.
