ARM: 6771/1: vexpress: add support for multiple core tiles The current Versatile Express BSP defines the MACHINE_START macro in the core tile code. This patch moves this into the generic board code and introduces a method for determining the current tile at runtime, allowing the Kernel to have support for multiple tiles compiled in. Tile-specific functions are executed via a descriptor struct containing the correct implementations for the current tile.

ARM: vexpress: Start using new Versatile Express infrastructure This patch starts using all the configuration infrastructure. - generic GPIO library is forced now - sysreg GPIOs are used as MMC CD and WP information sources; thanks to this MMCI auxiliary data is not longer necessary - DVI muxer and mode control is removed from non-DT V2P-CA9 code as this is now handled by the vexpress-dvi driver - clock generators control is removed as is being handled by the common clock driver now - the sysreg and sysctl control is now delegated to the appropriate drivers and all related code was removed - NOR Flash set_vpp function has been removed as the control bit used does _not_ control its VPP line, but the #WP signal instead (which is de facto unusable in case of Linux MTD drivers); this also allowed the remove its DT auxiliary data The non-DT code defines only minimal required number of the config devices. Device Trees are updated to make use of all new features. Signed-off-by: Pawel Moll <pawel.moll@arm.com>

ARM: vexpress: Simplify SMP operations for DT-powered system As all cores must be properly described in the Device Tree, there is no point in getting their numbers from SCU on A5/A9 platforms. This significantly simplifies the code, removing the need for flat-tree scanning and early static mapping. Signed-off-by: Pawel Moll <pawel.moll@arm.com>
