Subject: boot/image-board.c: boot_get_fpga(): pass compatible flag to fpga_load()
X-Git-Url: http://git.dujemihanovic.xyz/html/static/gitweb.css?a=commitdiff_plain;h=4bd7222c6ba36715c5a4e1f6684bec63489e1acd;p=u-boot.git

boot/image-board.c: boot_get_fpga(): pass compatible flag to fpga_load()

For E.G. signed FPGA bitstreams, similar to how it is done for the FPGA
loading from SPL since commit 71f1a5392aad ("spl: fit: pass real compatible
flags to fpga_load()").
