Create new configuration keywords:
RsaKeyModulusFile: pubkey modulus
RsaPssSigBlFile: bootloader rsa pss signature
RsaPssSigBctFile: bct rsa pss signature
Sample Configuration file update_bl_sig.cfg
RsaKeyModulusFile = pubkey.mod;
RsaPssSigBlFile = bl.sig;
where pubkey.mod and bl.sig are files that contain the public key
modulus and bootloader's rsa-pss signature respectively.
public key modulus and signature are created through utilities
outside cbootimage.
Command line example:
$ cbootimage -s tegra210 -u update_bl_sig.cfg image.bin image.bin-bl-signed
Above three new keywords added in this CL are only implemented support
for T210.

+ file_type rsa_filetype = file_type_bin;

+ ARSE_RSA_PARAM_MAX_BYTES,

Why do we need a variable "ras_filetype"? Why not just pass
file_type_bin directly as the function parameter?
