2020-08-06board_f: Introduce arch_setup_bdinfo initcallOvidiu Panait
Certain architectures (ppc, mips, sh, m68k) use setup board_part1 and setup_board_part2 calls during pre-relocation init to populate gd->bd boardinfo fields. This makes the generic init sequence cluttered with arch-specific ifdefs. In order to clean these arch-specific sequences from generic init, introduce arch_setup_bdinfo weak initcall so that everyone can define their own bdinfo setup routines.

2020-06-25bdinfo: arm: Move ARM-specific info into its own fileSimon Glass
We don't really want to have ARM-specific code in a generic file. Create a new arch-specific function to hold it, and move it into that. Make the function weak so that any arch can implement it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2020-06-25bdinfo: Export some basic printing functionsSimon Glass
At present the functions to print a number and a frequency are static. We want to move some of the code in here to an arch-specific file. For consistency that code should use these same functions. So export them with an appropriate name. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2018-11-07Revert "board_f: Use static print_cpuinfo if CONFIG_CPU is active"Bin Meng
This reverts commit c0434407b595f785fc7401237896c48c791b45fd. It turns out commit c0434407b595 broke some boards which have DM CPU driver with CONFIG_DISPLAY_CPUINFO option on. These boards just fail to boot when print_cpuinfo() is called during boot. Fixes are already sent to ML and in u-boot-dm/next, however since we are getting close to the v2018.11 release, it's safer we revert the original commit. This commit should be reverted after v2018.11 release. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
