* ARM: mach-types: don't generate header at buildtimeAhmad Fatoum2024-01-042-2/+2
| | | | | | | | | | | | Now that we have removed 4642 machine types unused by barebox, we are just left with 65 boards. Let's just include the generated header in the source tree and stop generating the header anew at build time.

* ARM: MXS: fix breakage for non-DT boardsAhmad Fatoum2022-10-121-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | boarddata, the third argument passed from barebox PBL to barebox proper, is usually either a pointer to an optionally compressed flattened device tree or a machien type integer casted to a pointer. In order to support device trees located in the first 8192 bytes of address space, barebox has been trying to dereference boarddata, before falling back to treating it as integer. This resulted in breakage as boarddata may be an integer not divisible by 4 and thus an unaligned exception would occur. The already existing barebox_arm_boarddata mechanism sidesteps this issue: With it, the machine type integer is not passed as is, but the address of a suitably aligned structure that contains it is passed instead. Searching for MACH_TYPE in arch/arm/boards shows 5 boards to be affected in-tree, which are all fixed with this commit.

* 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.

* defaultenv-2: Make use of nonvolatile variablesSascha Hauer2014-11-064-18/+2
| | | | | | | | | | | | | | 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.

It is assumed that most board specific clock setup is done based on copy/paste from U-Boot.
