* x86: fix lifting kernel CPU requirements and always enable PAEDaniel Golle2017-05-051-2/+4
| | | | | | | | | commit 89878f60f4 x86: lift kernel minimum CPU requirement to Pentium MMX caused kconfig havoc. Fix this and make sure PAE is enabled even on legacy CPUs as the minimum required CPU has been Pentium MMX for a while now and hence PAE is supported even on the x86_legacy target.

* x86: enable 4G high memory support for generic (32bit) subtargetJo-Philipp Wich2017-04-271-0/+3
| | | | | | | | | This is required to fully support a number of 32bit x86 systems equipped with more than one GB ram, e.g. certain Atom CPU machines. Ref: https://forum.lede-project.org/t/17-01-1-x86-doesnt-detect-all-of-the-ram/3295 Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* x86: enable CPU frequency scalingLucian Cristian2016-08-031-1/+4
| | | | | | | | | CPU frequency scaling enables the operating system to scale the CPU frequency up or down in order to save power. CPU frequencies can be scaled automatically depending on the system load, in response to ACPI events, or manually by userspace programs. Signed-off-by: Lucian Cristian <lucian.cristian@gmail.com>
