mpc83xx: Don't allow W and G bits in IBATs

2023-05-01T22:59:33Z

The "Programming Environments Manual for 32-Bit Implementations of the PowerPC™ Architecture" says "W and G bits are not defined for IBAT registers. Attempting to write to these bits causes boundedly-undefined results" The "e300 Power Architecture™ Core Family Reference Manual" says the same: "Neither the W or G bits of the IBAT registers should be set. Attempting to write to these bits causes boundedly-undefined results." Remove the possibility to set those bytes.

global: Finish CONFIG -> CFG migration

At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

mpc83xx: Migrate BATS config to Kconfig

2019-05-21T05:52:33Z

The BATs (block address translation registers) determine the initial memory window mappings. Hence, they must be known at compile time and cannot be implemented in the DT mechanism. 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
