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>
2016-01-25arch/powperpc: Fix start_align due to use of __ffs64() instead ffs64()Ashish kumar
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.

2016-01-19Add more SPDX-License-Identifier tagsTom Rini
In a number of places we had wordings of the GPL (or LGPL in a few cases) license text that were split in such a way that it wasn't caught previously. Convert all of these to the correct SPDX-License-Identifier tag. Signed-off-by: Tom Rini <trini@konsulko.com>
2015-11-05powerpc: Remove __ilog2_u64 and ffs4 from bitopsFabio Estevam
Remove __ilog2_u64 and ffs4 from powerpc bitops to align with the kernel implementation. Use the generic __ffs64 instead of a custom powerpc implementation.

2011-09-29powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun
Unified DDR driver is maintained for better performance, robustness and bug fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of overall improvement. It requires changes for board files to customize platform-dependent parameters. To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx in the header file. No more boards will be accepted without such definition. Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1 and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.
