The tegra crypto driver uses the tegra_chip_uid API for the RNG calculation. If one wants to build tegra-aes as a module, then tegra_chip_uid needs to be exported. I have also posted "arm: tegra: export tegra_chip_uid" to the mach-tegra maintainers to get this patch into their tree, but for compiling the "crypto: driver for Tegra AES hardware" patch, "arm: tegra: export tegra_chip_uid" has to be present. I leave it to the linux-crypto maintainers to decide how they want to tackle this situation. In order to facilitate smooth compilation of the actual crytpo driver patch sending the tegra_chip_uid as well.
