2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2010-10-14powerpc/85xx: add DIU support to the Freecale P1022DS reference boardTimur Tabi
The Freescale P1022DS has an on-chip video controller called the DIU, and a driver for this device already exists. Update the platform file for the P1022DS reference board to enable the driver, and update the defconfig for Freescale MPC85xx boards to add the driver.

2010-08-04powerpc/85xx: Introduce support for the Freescale P1022DS reference boardTimur Tabi
Introduce basic support for the Freescale P1022DS reference board, based on the Freescale BSP for this board. This patch excludes the DIU, SSI, and MMC/SD drivers. Only a 36-bit DTS is provided. Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS. This means enabling 64-bit physical address support, increasing the maximum zone order to 12 (to allow the DIU driver to allocate large chunks), and clean up the audio options to disable the deprecated OSS support.

2009-12-18powerpc/defconfigs: Set HZ=100 on pseries and ppc64 defconfigsAnton Blanchard
Now we have high res timers there is less of a reason for a high HZ value. Furthermore I think there a few reasons we should reduce HZ to 100: - Timer interrupt overhead. While this overhead is small, there are applications that are very sensitive to jitter (eg some HPC apps). - Issues with the timer wheel code. When coming out of NO_HZ idle we work our way through the timer code one tick at a time. If we have been idle a long time, this adds up - I sometimes see milliseconds of time spent in that loop. Long term we should fix the timer wheel algorithm, but for now if we reduce HZ then we reduce the amount of work the timer code has to do when coming out of idle.
