The NovaThor U8500 SoC was released by ST-Ericsson in 2011. It was used for some development boards like the CALAO Systems Snowball SBC, but mass production was primarily for Android smartphones like the Samsung Galaxy S III mini.
Previous support for U8500 was removed in commit 68282f55b846 ("arm: Remove unused ST-Ericsson u8500 arch") since none of the boards were converted to generic boards before the deadline.
The new code does not have much in common with the previous code. I have completely rewritten everything, embracing the Driver Model and device trees wherever possible.
The U8500 support is a bit more minimal for now - my primary use case is to use U-Boot as alternative bootloader for some of the U8500 Samsung smartphones. At the moment U-Boot is chain-loaded from the original Samsung bootloader. A side effect of this is that we can (temporarily) get away without implementing some functionality
- e.g. all clocks are already enabled by the original bootloader.
More functionality will be added in future patches.
