43381474ff arch/powperpc: Fix start_align due to use of __ffs64() instead ffs64()
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.

5b8031ccb4 Add more SPDX-License-Identifier tags
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.

2d2f490dd5 powerpc: Remove __ilog2_u64 and ffs4 from bitops
Remove __ilog2_u64 and ffs4 from powerpc bitops to align with the
kernel implementation.

Use the generic __ffs64 instead of a custom powerpc implementation.

d29d17d7ba powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driver
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.
