The buffer is a circular buffer, so 133 if it overflows, earlier output is discarded. 134 135 Note that this is not currently supported in SPL.

The bloblist 721 is set up in the first part of U-Boot to run (TPL, SPL or U-Boot 722 proper), and this sane bloblist is used for subsequent stages. 723 724config BLOBLIST_ADDR 725 hex "Address of bloblist" 726 depends on BLOBLIST 727 default 0xe000 if SANDBOX 728 help 729 Sets the address of the bloblist, set up by the first part of U-Boot 730 which runs. Subsequent U-Boot stages typically use the same address. 731 732config BLOBLIST_SIZE_RELOC 733 hex "Size of bloblist after relocation" 734 depends on BLOBLIST 735 default BLOBLIST_SIZE 736 help 737 Sets the size of the bloblist in bytes after relocation. Since U-Boot 738 has a lot more memory available then, it is possible to use a larger 739 size than the one set up by SPL. This bloblist is set up during the 740 relocation process. 741 742endmenu 743 744source "common/spl/Kconfig" 745 746config IMAGE_SIGN_INFO 747 bool 748 select SHA1 749 select SHA256 750 help 751 Enable image_sign_info helper functions. 752 753if IMAGE_SIGN_INFO 754 755config SPL_IMAGE_SIGN_INFO 756 bool 757 select SHA1 758 select SHA256 759 help 760 Enable image_sign_info helper functions in SPL. 761 762endif 763
