powerpc: add explicit OF includes

2013-10-10T01:04:11Z

When removing prom.h include by of.h, several OF headers will no longer be implicitly included. Add explicit includes of of_*.h as needed.

powerpc/irq: Remove IRQF_DISABLED

2011-11-08T03:51:46Z

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed. Signed-off-by: Yong Zhang Acked-by: Arnd Bergmann Acked-by: Geoff Levand Signed-off-by: Benjamin Herrenschmidt

powerpc/4xx: Add optional "reset_type" property to control reboot via dts

2010-05-05T16:51:54Z

By setting "reset_type" to one of the following values, the default software reset mechanism may be overidden. Here the possible values of "reset_type": 1 - PPC4xx core reset 2 - PPC4xx chip reset 3 - PPC4xx system reset (default) This will be used by a new PPC440SPe board port, which needs a "chip reset" instead of the default "system reset" to be asserted.

powerpc/44x: Fix L2-cache support for 460GT

2010-02-10T13:21:14Z

Also set L2C_CFG_RDBW on 460GT platforms and not only on 460EX. Signed-off-by: Stefan Roese Cc: Josh Boyer Signed-off-by: Josh Boyer

[POWERPC] 4xx: Create common ppc4xx_reset_system() in ppc4xx_soc.c

2008-04-03T01:44:56Z

This patch creates a common system reset routine for all 40x and 44x systems. Previously only a 44x routine existed. But since this system reset via the debug control register is common for 40x and 44x let's share this code for all those platforms in ppc4xx_soc.c. This patch also enables CONFIG_4xx_SOC for all 40x and 44x platforms. Tested on Kilauea (405EX) and Canyonlands (440EX). Signed-off-by: Stefan Roese Signed-off-by: Josh Boyer

[POWERPC] 4xx: Add PPC4xx L2-cache support (440GX)

2008-03-26T12:27:54Z

This patch adds support for the 256k L2 cache found on some IBM/AMCC 4xx PPC's. It introduces a common 4xx SoC file (sysdev/ppc4xx_soc.c) which currently "only" adds the L2 cache init code. Other common 4xx stuff can be added later here. The L2 cache handling code is a copy of Eugene's code in arch/ppc with small modifications. Tested on AMCC Taishan 440GX.
