| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New microblaze systems uses two buses. One for memories and flashes and the second for low-speed peripherals which can run on different CLK. This is the reason why the kernel is trying to read clock-frequency directly from node. If there is then the kernel will work with it. If not then cpu CLK is used. Signed-off-by: Michal Simek <monstr@monstr.eu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microblaze little-endian toolchain exports __MICROBLAZEEL__ which is used in the kernel to identify little/big endian. The most of the changes are in loading values from DTB which is always big endian. Little endian platforms are based on new AXI bus which has impact to early uartlite initialization.
