Subject: sysreset: qemu virt: Use __raw_writel()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0bcd158db30aa14aa6add56060626388079c50cf;p=thirdparty%2Fu-boot.git

sysreset: qemu virt: Use __raw_writel()

The virt ctrl register seems to be native endian, currently this driver
uses writel(), which works by luck because its currently broken on m68k.

Use __raw_writel() instead to avoid breaking this driver when the
endianness of writel() is fixed.
