FreeBSD's boot loader (named loader(8)) needs CONFIG_API to be enabled, but trying to build an U-Boot from trunk with both CONFIG_API and CONFIG_BLK (as required for Rockchip SoC's?) leads to the following build failure: $ CROSS_COMPILE=arm-none-eabi- gmake tinker-rk3288_defconfig all ... CC api/api_storage.o api/api_storage.c: In function 'dev_read_stor': api/api_storage.c:334:9: error: 'struct blk_desc' has no member named 'block_read' if ((dd->block_read) == NULL) { ^~ api/api_storage.c:339:11: error: 'struct blk_desc' has no member named 'block_read' return dd->block_read(dd, start, len, buf); ^~ api/api_storage.c:340:1: warning: control reaches end of non-void function [-Wreturn-type] } ^ gmake[2]: *** [scripts/Makefile.build:281: api/api_storage.o] Fehler 1 gmake[1]: *** [Makefile:1229: api] Fehler 2 gmake: *** [Makefile:460: __build_one_by_one] Error 2 I applied the following fix, but the product doesn't boot. Perhaps that's not a property of the fix though: Yours, Robert Clausecker --- diff --git a/api/api_storage.c b/api/api_storage.c index e80818df1c..a5357bc9cf 100644 --- a/api/api_storage.c +++ b/api/api_storage.c @@ -331,10 +331,14 @@ lbasize_t dev_read_stor(void *cookie, void *buf, lbasize_t len, lbastart_t start if (!dev_stor_is_valid(type, dd)) return 0; +#ifdef CONFIG_BLK + return blk_dread(dd, start, len, buf); +#else if ((dd->block_read) == NULL) { debugf("no block_read() for device 0x%08x\n", cookie); return 0; } return dd->block_read(dd, start, len, buf); +#endif /* defined(CONFIG_BLK) */ }
