[PATCH][2.6] Fix Makefiles for CONFIG_EMBEDDED_RAMDISK

[Dimitri Torfs]

Hi,

  here are patches that fix the arch/mips/Makefile and
  arch/mips/ramdisk/Makefile when an embedded ramdisk image needs to
  be included through the CONFIG_EMBEDDED_RAMDISK option.

I'm curious as to why this is a mips specific feature. Does anyone know?

There's little machine dependence as you noticed; just the linker script
would need to be fixed as it's hardwired to mips.
