      [POWERPC] PS3: Bootwrapper support. · bafdb645
      Geoff Levand 提交于
      Add support to build the PS3 flash rom image and remove some unneeded
      lmb calls.
      
      The PS3's lv1 loader supports loading gzipped binary images from flash
      rom to addr zero. The loader enters the image at addr 0x100.
      
      In this implementation a bootwrapper overlay is use to arrange for the
      kernel to be loaded to addr zero and to have a suitable bootwrapper
      entry at 0x100.  To construct the rom image, 0x100 bytes from offset
      0x100 in the kernel is copied to the bootwrapper symbol
      __system_reset_kernel.  The 0x100 bytes at the bootwrapper symbol
      __system_reset_overlay is then copied to offset 0x100.  At runtime the
      bootwrapper program copies the 0x100 bytes at __system_reset_kernel to
      addr 0x100.
      
      zImage.ps3 is a wrapped image that contains a flat device tree, an lv1
      compatible entry point, and an optional initrd.  otheros.bld is the gzip
      compresed rom image built from zImage.ps3.  otheros.bld is suitable for
      programming into the PS3 boot flash memory.
