[ARM] 5473/1: U300 core machine support This adds core support for the ST-Ericsson U300 series platforms: U300, U330, U335 and U365. Supports memory mappings, interrupt controller, system timer (clocksource and clockevents), and binds to the existing drivers for the PrimeCells used in this design: PL190 (VIC), PL180 (MMC/SD host) and PL011 (UART). This is intented to serve as starting point for our mainling work, more patches to follow.

ARM: 5910/1: ARM: Add tmp register for addruart and loadsp Otherwise more complicated uart configuration won't be possible. We can use r1 for tmp register for both head.S and debug.S. NOTE: This patch depends on another patch to add the the tmp register into all debug-macro.S files. That can be done with: $ sed -i -e "s/addruart,rx|addruart, rx/addruart, rx, tmp/" arch/arm/*/include/*/debug-macro.S Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

.macro addruart, rx, tmp
tree-wide: Assorted spelling fixes In particular, several occurances of funny versions of 'success', 'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address', 'beginning', 'desirable', 'separate' and 'necessary' are fixed.
