From 689088f9dae8b823651095a34aff76cc61099ef9 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Sat, 4 Jan 2020 18:45:17 +0100 Subject: arm: Add support for ST-Ericsson U8500 SoC 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.
