BAT register usage with 745x CPUs
We need some information to try and fix a problem we have with the most
recent 2.4.x kernels (a particular area of memory where the NVRAM is
located, cannot be accessed anymore once the Linux kernel boots, looks
like it's being mapped out).
The machine uses a 745x CPU, and I understand that the memory on these
machines is mapped using the BAT registers.
Is this correct, and if so, which registers are used/what is the
arrangement? (Or where could I look to get this info).
