[ Upstream commit c6ea7e9747318e5a6774995f4f8e3e0f7c0fa8ba ]
Having the zload address at 0x8060.0000 means the size of the uncompressed kernel cannot be bigger than around 6 MiB, as it is deflated at address 0x8001.0000.
This limit is too small; a kernel with some built-in drivers and things like debugfs enabled will already be over 6 MiB in size, and so will fail to extract properly.
To fix this, we bump the zload address from 0x8060.0000 to 0x8100.0000.
This is fine, as all the boards featuring Ingenic JZ SoCs have at least 32 MiB of RAM, and use u-boot or compatible bootloaders which won't hardcode the load address but read it from the uImage's header.
