e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernels
Newer Linux kernels can overrun the initial memory window used for booting with their BSS area. When this happens, they overwrite the FDT and silently fail to boot. On e300 CPUs, the Linux kernel uses an initial BAT covering the first 256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value allowed by Linux. This will allow very large kernels to boot. Signed-off-by: Ira W.
