- Subject: [PATCH] powerpc: add compressed zImage for mpc85xx
- Add a universal zImage which can be loaded by mpc85xx boards at
- load address 0x3000000. This allows boards to boot kernels larger than
- 16MB even if the image is loaded temporarily from NAND at offset
- 0x1000000 which some bootloaders do by default.
