In order to start upstreaming Broadcom SoC support, create a starting hierarchy, arch and dts files. The first support SoC family that is planned is the BCM281XX (BCM11130/11140/11351/28145/28155) family of dual A9 mobile SoC cores. This code is just the skeleton code for get the machine upstreamed. It has been made MULTIPLATFORM compatible. Next steps ---------- Upstream a basic set of drivers - sufficient for a console boot to ramdisk. These will includer timer, gpio, i2c drivers. After this basic set, we will proceed with a more comprehensive set of drivers for the 281XX SoC family. v2 patch mods -------- - Remove l2x0_of_init call as there were problems with the code. A separate patch will be submitted with cache init code - Rename capri files and refs to bcm281xx-based names - Add bcm281xx binding doc - various misc cleanups v3 patch mods ------------- - Remove extra #include lines - Remove remaining references to capri - dt uart chipset string added - cleaned up chip # references v4 patch mods ------------- - swap order of compatible definitions for uart - fix typo v5 patch mods ------------- - Rename bcm281xx to bcm11351 in dts+code, leaving references to bcm281xx only in help+comments. v6 patch mods ------------- - fix typo in uart 'compatible' string Signed-off-by: Christian Daudt <csd@broadcom.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>
