| * ARM: zynqmp: add support for Xilinx ZCU104 boardMichael Tretter2018-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Xilinx Zynq Ultrascale+ MPSoC architecture (ZynqMP) and the Xilinx ZCU104 board. Barebox is booted as BL33 in EL-1 and expects that a BL2 (i.e. the FSBL) already took care of initializing the RAM. Also for debug_ll, the UART is expected to be already setup correctly. Thus, you have to add the Barebox binary to a boot image as described in "Chapter 11: Boot and Configuration" of "Zynq Ultrascale+ Device Technical Reference Manual".

| * ARM: aarch64: compile with general-regs-onlyMichael Tretter2018-12-101-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Without this flag, gcc generates code to save the Q/V registers to the stack for handling the va_list in pr_print(). Saving the registers is useless, as the registers are never restored, but accessing the registers to save them hangs the CPU. Follow the Linux arch/arm64/Makefile and use the general-regs-only flag to prevent usage of floating point and Advanced SIMD register.

| * ARM i.MX35: Add support for the Amazon Kindle3Alexander Kurz2016-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Amazon Model No. D00901 Kindle3 is an E-Book reader based on the i.MX35 SOC. The device boots in internal boot mode from a build-in eMMC, alternatively the device may be set into USB-downloader mode when the Vol+ key is pressed on startup. Add support for this device and make barebox a drop-in replacement for the factory shipped u-boot image. Constraints for the use as drop-in replacement: - imximg header (offset 0x400) has a maximum size of 2kB minus 16 byte since the last 16 bytes are used to store a vendor specific hardware desctription identifier - the bootloader space (application plus env) is limited to 256kB minus 16 bytes when installed with offset of 4kB (the u-boot offset was 3kB). A vendor specific device identifier is stored in the gap between application and kernel. The vendor specific identifiers should not be overwritten. Notable features: - Support for eMMC, USB, UART, I2C, SPI and Keys (except keyboard) - Full support for vendor specific ATAGs - usbserial barebox console access by pressing Select button at startup, alternatively full console support on connector J14.

* arm: Disable unaligned accessesAndrey Smirnov2015-10-151-0/+7
| | | | | | | | | | | | | | | | | | | From reading ARM architecture related documentation if appears that while unaligned memory access is supported by the processor in general it is not supported if MMU is disabled. The problem in question can be easily reproduced by building the code without this patch, MMU disabled, and trying to run 'memtest' command. Which would in turn call mem_test() which would eventually call show_progress(). That last function, if build without -mno-unaligned-access would result in unaligned memory access which would result in Barebox hanging. This patch instructs the compiler to not generate any unaligned accesses to memory thus avoiding the problem.

| * ARM: do not specify -static and -pie at the same timeLucas Stach2015-03-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | PIE is a form of dynamic linking and thus inherently incompatible with -static. It worked ok as the current behavior of ld.bfd is to not respect -static if -pie has been specified. ld.gold and future versions of ld.bfd will fail to link if both of those incompatible switches are specified at the same time.

* arm: do section garbage collection also with modules enabledLucas Stach2014-12-171-2/+0
| | | | | | | | | | | | | | | | | | A lot of the arm build (especially PBL stuff) depends on section garbage collection to be enabled. If it is disabled a lot of targets fail to link properly. If module support is enabled garbage collection was disabled on the premise that we throw away too many function which may be needed in later modules. The proper way to keep the functions around for use in modules, which already works, is to annotate them with EXPORT_SYMBOL. As module support is still marked as experimental I think it's reasonable to expect users to make sure all symbols that are used by their modules are properly annotated.

* scripts: mk-am3xxx-spi-image: fix wrong assumptions about SPI imagesSascha Hauer2014-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | We assumed that there is a special image format for SPI. This is not the case. The AM33xx can boot either images generated with omap_signGP or raw images which only have the image size and load address in front of the image. Whether these images are booted from SPI or another boot medium doesn't matter. The only special thing about SPI is that the image is in big endian format. - renames mk-am3xxx-spi-image.c to mk-omap-image.c as the image format is not only supported by AM3xxx but also by the OMAP SoCs - removes the option to specify the SoC - introduces -s to build a big endian image - detects if an image already is an image generated with omap_signGP So the behaviour is like this: raw image -> mk-omap-image -> prepend size/address -> image for SD/MMC raw image -> mk-omap-image -s -> prepend size/address, big endian swap -> image for SPI CH image -> mk-omap-image -> nothing, input == output CH image -> mk-omap-image -s -> big endian swap -> image for SPI Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
