Well probably I'm missing something :) Here's a TravisCI job for ARC that passes perfectly fine: https://travis-ci.org/abrodkin/u-boot/jobs/362026822 Stuff that is built there is here: https://github.com/abrodkin/u-boot/commits/staging-arc Basically it's: * v2018.05-rc1 + * My last PR (tags/arc-for-2018.05) + * [This] "disable stack-usage" patch ------------------------>8------------------------ # git log --oneline 7917ac883723 Makefile: Disable stack-usage check for ARC 9fe2b77b313b ARC: HSDK: Enable SPI flash support 11007a25b835 ARC: HSDK: Add platform-specific commands 416c03d2f09f ARC: Bump ARC tools used in TravisCI to the most recent release arc-2017.09 94f247d0c145 ARC: AXS10x: DTS: Remove unused interrupt properties 645b5afbb821 (tag: v2018.05-rc1, mainline/master) Prepare v2018.05-rc1 ------------------------>8------------------------ -Alexey _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
