[PATCH 04/11] arch: Set IORESOURCE_SYSTEM_RAM to System RAM

2015-12-14 Thread Toshi Kani 
Set IORESOURCE_SYSTEM_RAM to the flags of resource ranges with
"System RAM", "Kernel code", "Kernel data", and "Kernel bss".

Note, IORESOURCE_SYSRAM (i.e. modifier bit) is set to the flags
when IORESOURCE_MEM is already set.  IORESOURCE_SYSTEM_RAM is
defined as (IORESOURCE_MEM|IORESOURCE_SYSRAM).

Note2, Some archs do not set flags for children nodes, such as
"Kernel code".  This patch keeps the flags unset in such cases.
