I'm working off v2015.04-rc4, which is recent enough. Having this diff: diff --git a/include/configs/sunxi-common.h b/include/configs/sunxi-common.h index 61a45e1..14ac9db 100644 --- a/include/configs/sunxi-common.h +++ b/include/configs/sunxi-common.h @@ -13,6 +13,8 @@ #ifndef _SUNXI_COMMON_CONFIG_H #define _SUNXI_COMMON_CONFIG_H +#define CONFIG_OLD_SUNXI_KERNEL_COMPAT 1 + #ifdef CONFIG_OLD_SUNXI_KERNEL_COMPAT /* * The U-Boot workarounds bugs in the outdated buggy sunxi-3.4 kernels at the Results in this .config: grep CONFIG_OLD_SUNXI_KERNEL_COMPAT u-boot-out/.config # CONFIG_OLD_SUNXI_KERNEL_COMPAT is not set So this is not, in fact, specific to the SPL. Still, why does it happen? Perhaps the fact that OLD_SUNXI_KERNEL_COMPAT is defined as a Kconfig option, defaulted to n, implies that a define in the config header is not sufficient to enable it in Kconfig? -- Paul Kocialkowski, Replicant developer Replicant is a fully free Android distribution running on several devices, a free software mobile operating system putting the emphasis on freedom and privacy/security.
