This should be the platform_data register for CESA in 3.1.1:
plat-orion/common.c +945:
void __init orion_crypto_init(unsigned long mapbase,
                              unsigned long srambase,
                              unsigned long sram_size,
                              unsigned long irq)
{
        fill_resources(&orion_crypto, orion_crypto_resources,
                       mapbase, 0xffff, irq);
        orion_crypto.num_resources = 3;
        orion_crypto_resources[2].start = srambase;
        orion_crypto_resources[2].end = srambase + sram_size - 1;

        platform_device_register(&orion_crypto);
}
