2012-02-23ARM: at91/board-dt: drop default consoleJean-Christophe PLAGNIOL-VILLARD
This default console mechanism is not used if the console is selected by command line (console= parameter). Dropping this will simplify the compilation of multiple SoC in the same kernel image.

2012-02-23Atmel: move console default platform_device to serial driverJean-Christophe PLAGNIOL-VILLARD
This variable spread on every SoC that is using the atmel_serial.c driver can be included directly into the latter. This will allow to compile multiple soc in the same kernel.

Change slow_clock()/at91_slow_clock() prototype to accept the PMC base address and one or two RAM controller addresses by parameters. The r0, r1 and r2 registers are used differently and preserved during function call. Those values are defined in pm.c and slow_clock() function is called from there with its new parameters.

2012-02-03ARM: at91: implement the standby function for pm/cpuidleDaniel Lezcano
This patch groups the self-refresh on/cpu_do_idle/self-refresh off into a single 'standby' function. The standby routine for rm9200 has been turned into an asm routine to have a better control of the self refresh and to prevent a memory access when running this code. Draining the write buffer is done automatically when switching for the self refresh on sam9, so the instruction is added to the rm9200 only.

2012-02-03ARM: at91: remove wait_for_interrupt definitionDaniel Lezcano
All the "wait_for_interrupt" definition are aliases to cpu_do_idle. Only the rm9200 has an asm routine to switch to wfi. But the cpu_do_idle for this platform has exactly the same asm routine. arch/arm/mm/proc-arm920.S .. ENTRY(cpu_arm920_do_idle) mcr p15, 0, r0, c7, c0, 4 @ Wait for interrupt .. Then it is safe to invoke cpu_do_idle for this platform. As all the wait_for_interrupts are definition for cpu_do_idle, let's remove it and replace its invokation by cpu_do_idle.
