This patchset updates the PPC memory layout and memtest: - Memory regions on PPC are redefined to prevent corruption of critical memory areas while running the memtest. - To support the memory test framework with cache disabled, a TLB remapping function is added for the memtest to enable/disable caching on a mapped memory region. - To prevent memtest failure, the memory test is updated to exclude memory region at the bank start. Finally, the configuration files are updated for the DA923RC and P2020RDB.
