Currently the space between kernel_addr_r and the fdt_addr_r is only 32MB. To have enought space to load kernel images bigger than 32MB change the variables to a feasible value. The new environment variables layout is based on the scheme from "include/configs/ti_armv7_common.h". The CONFIG_SYS_LOAD_ADDR value is set to 0x42000000. With that we have the same value as for the kernel_addr_r. Signed-off-by: Heiko Thiery <heiko.thiery@gmail.com> Reviewed-by: Michael Walle <michael@walle.cc>
