2019-05-21mpc83xx: Use pre-defined asm functionsMario Six
For a lot of inline assembly calls in the mpc8xxx and mpc83xx directories, we already have convenient pre-defined helper functions, but they're not used, resulting in hard-to-read code. Use these helper functions where ever possible and useful. Signed-off-by: Mario Six <mario.six@gdsys.cc>
2019-05-21mpc83xx: Migrate CONFIG_SYS_{BR, OR}*_PRELIM to KconfigMario Six
Migrate the BR/OR settings to Kconfig. These must be known at compile time, so cannot be configured via DT. Configuration of this crucial variable should still be somewhat comfortable. Hence, make its fields configurable in Kconfig, and assemble the final value from these. Signed-off-by: Mario Six <mario.six@gdsys.cc>
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>

Incorrect DDR law was created in case of B4860qds after commit 2d2f490d. Return value of ffs64() differs from __ffs64(), eg. ffs64(0x80000000) = 0x20 __ffs64(0x80000000) = 0x1f As a result of this change, callers need to adjust the expected return value by removing -1.

After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one.

2014-05-13PPC 85xx QEMU: Always assume 1 coreAlexander Graf
We only need u-boot to bother about a single core in the QEMU machine. Everything that would require additional knowledge of more cores gets handled by QEMU and passed straight into the payload we execute. Because of this setup, it would be counterproductive to enable SMP support in u-boot. We would have to rip CPUs out of already existing spin tables and respin them from u-boot. It would be a pretty big mess. So only assume we have a single core. This fixes errors about CONFIG_MP being disabled. Signed-off-by: Alexander Graf <agraf@suse.de>
