Ben Dooks f4c24f36c3 ARM: SAMSUNG: Fixup endian issues in CPU detection
If the system is built for big endian, then the CPU identificaiton register
will be read in the wrong order. Fix this by using readl_relaxed() on the
register.

Olof Johansson 1a14f53271 ARM: SAMSUNG: print CPU id on probe
It's useful to get the CPU ID/rev printed during boot sometimes, so
add a line with that information. Given that the fields have moved
within the register over time, don't try to be clever and parse it --
just print the raw values for now.

Tomasz Figa d78c16ccde ARM: SAMSUNG: Remove remaining legacy code
After refactoring suspend/resume, which was last part with dependencies
on legacy code, all Kconfig symbols related to Samsung ATAGS support can
be deselected and more unused code removed. This includes most of s5p-*
code as well, as s5pv210 was their last user.

Heiko Stuebner a31ccfd626 ARM: SAMSUNG: remove unneeded s3c24xx_init_cpu()
The function is nearly empty and samsung_cpu_rev is static
so already 0 making the function obsolete, therefore remove
it.
