From: Thomas Petazzoni Date: Sat, 3 Oct 2015 19:44:15 +0000 (+0100) Subject: configs: fix build of calao_usb_a9g20_lpw_defconfig X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3cb668d5b5272ab5d763a11264c28aee3fa1849a;p=buildroot.git configs: fix build of calao_usb_a9g20_lpw_defconfig Both the Barebox and AT91Bootstrap patches for the Calao USB A9G20 board are located in the same directory, board/calao/usb-a9g20-lpw/, with only a prefix making a difference between whether they apply to Barebox or AT91Bootstrap. Unfortunately, since commit 0eba4759fab9d093afacac77a0ac31f1f0b3cceb ("packages: apply custom patches using *.patch instead of -*.patch"), the logic to apply custom patches in Barebox and AT91Bootstrap has been changed from applying -*.patch to applying *.patch (in order to be consistent with what we do for all packages in Buildroot). However, this had the effect of trying to apply both the AT91Bootstrap and Barebox patches on both packages, which obviously cannot work. This commit fixes that by moving patches around, and switching to use BR2_GLOBAL_PATCH_DIR.
