* arch/arm/boards: Replace license and copyright boilerplate by SPDX identfiersUwe Kleine-König2020-05-252-28/+5
| | | | | | | | | | | | | | | | This adapts all files that were identifed by licensecheck (https://salsa.debian.org/build-common-team/licensecheck.git) as licensed under the GPL. The advantage is that these specifiers are machine-parseable which helps license conformance, e.g. for packaging barebox in Debian. While touching these files also do some minor comment reformatting to get some uniform layout.

* ARM: zynq: zed: partially revert zynq_cpu_lowlevel_init() chnagesLucas Stach2020-01-141-0/+1
| | | | | | | | | | | | | Calling arm_cpu_lowlevel_init() from zynq_cpu_lowlevel_init() adds a stack push/pop to the latter function which doesn't work this early in the boot. As the BootROM apparently hands proccessor control to us in abort(!?!) mode, setting up a stack requires duplicating most of arm_cpu_lowlevel_init(). To get around this catch-22 move the call to arm_cpu_lowlevel_init back into the board lowlevel start function, so we don't need a stack at all.

* ARM: zynq: zedboard: allow lowlevel init to be called as second stageLucas Stach2019-12-111-0/+10
| | | | | | | | | | | | | | | If the code is already executing in DRAM, the PS7 init must not be executed, as it initializes the DRAM controller. As the OCM can be configured to an address which aliases with the DRAM address space we can't reliably infer if we are running from OCM or DRAM from the execution address. So instead of using the address, look at the OCM mapping, as the BootROM leaves a quite unique mapping behind with 192KB OCM mapped at the low address and 64KB mapped to the high address.

* ARM: zynq: zedboard: split out PS7 initLucas Stach2019-12-111-4/+9
| | | | | | | | | | | | Move the PS7 inititalization into its own function. This helps readability and logically splits the FPGA toolchain generated setup from the reset of the board init. Also execute the PS7 setup after the lowlevel CPU init, as this is the regular order used in the Barebox codebase.

* ARM: zynq: move header generation to zynq_mkimageLucas Stach2019-11-113-63/+24
| | | | | | | | | | Instead of generating a suitable image header with linker magic, move all of this into zynq_mkimage. The configuration file format and parsing is based on imx-image. This gets us one step further on the road to proper multi-image support. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: boards: Harmonize barebox_arm_reset_vector() prototypeSascha Hauer2019-03-181-1/+1
| | | | | | | | | | | | barebox_arm_reset_vector() is a global function but we never provided a prototype anywhere. The prototypes differ for the different boards, so to provide a common prototype we must harmonize them. void barebox_arm_reset_vector(uint32_t r0, uint32_t r1, uint32_t r2) Should be suitable for all boards.

* ARM: start: Fix image size calculationSascha Hauer2017-02-081-2/+2
| | | | | | | | | | In barebox_non_pbl_start() we do not run at the address we are linked at, so we must read linker variables using ld_var(). Since ld_var() current is not available on arm64 we create two zero sized arrays, one at the begin of the image and one at the end. The difference between both is the image size we are looking for.

* boards: Use nv.linux.bootargs.console for setting the console= commandline ↵Sascha Hauer2015-02-231-0/+0
| | | | | | | | | | | | parameter Using a dedicated variable makes it easier to change the console= parameter without affecting other values. Also the linux.bootargs.console variable is already used by common/console.c. Using the same variable in the environment avoids giving duplicate console= twice to the kernel Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Suggested-by: Teresa Gámez <t.gamez@phytec.de>

| | | | | | | | | | | | | | This file originates in Linux. Linux has it under include/linux/ directory since commit dccd2304cc90. Let's move it to the same place as well in barebox.

* defaultenv-2: Make use of nonvolatile variablesSascha Hauer2014-11-062-6/+1
| | | | | | | | | | | | | | This moves the variable assignments previously done in /env/config-board to non volatile variables in /env/nv/. This makes the settings adjustable by the user without editing a file. Most of the changes are simple conversions which for many boards makes /env/config-board unnecessary. Some boards had some logic to assign global.boot.default based on the current bootsource. This has been moved to /env/init/bootsource. An additional check is added to not overwrite a nv.boot.default should it exist. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: change signature of barebox_arm_entryLucas Stach2014-05-051-1/+1
| | | | | | | | | | | Mostly to make it clear that boarddata needs to be something we can dereference. As this is a pretty invasive change, use the opportunity to make the signature 64bit safe. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Set model and hostname at boardlevelSascha Hauer2013-08-162-1/+3
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
