mario.six@gdsys.cc 2b9ec762c4 rsa: Fix return value and masked error ... When signing images, we repeatedly call fit_add_file_data() with successively increasing size values to include the keys in the DTB. Unfortunately, if large keys are used (such as 4096 bit RSA keys), this process fails sometimes, and mkimage needs to be called repeatedly to integrate the keys into the DTB. This is because fit_add_file_data actually returns the wrong error code, and the loop terminates prematurely, instead of trying again with a larger size value. This patch corrects the return value by fixing the return value of fdt_add_bignum, fixes a case where an error is masked by a unconditional setting of a return value variable, and also removes a error message, which is misleading, since we actually allow the function to fail. A (hopefully helpful) comment is also added to explain the lack of error message. This is probably related to 1152a05 ("tools: Correct error handling in fit_image_process_hash()") and the corresponding error reported here: https://www.mail-archive.com/u-boot@lists.denx.de/msg217417.html Signed-off-by: Mario Six <mario.six@gdsys.cc>		2016-07-22 14:46:24 -04:00
