Subject: spl: Set up the bloblist in SPL
X-Git-Tag: v2019.01-rc1~27^2~18
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e945a726235af1adc2cadc93e86a39637ee6318d;p=oweals%2Fu-boot.git

spl: Set up the bloblist in SPL

The bloblist is normally set up in SPL ready for use by U-Boot. Add
a simple implementation of this to the common SPL code.
