+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.
