我正在使用Poky发行版2.0.1来构建u-boot v2015.07（移植任务）。但是，我遇到了以下错误

config.h 文件由 scripts / Makefile.autoconf 生成。我已经在 board / renesas / iwg20m_q7 / Kconfig 中添加了配置头文件 include / configs / iwg20m_q7.h 并声明了SYS_CONFIG_NAME，如下所示：
if TARGET_IWG20M
config SYS_BOARD
default "iwg20m_q7"
config SYS_VENDOR
default "renesas"
config SYS_CONFIG_NAME
default "iwg20m_q7"
endif
但是，我不知道$（CONFIG_SYS_CONFIG_NAME）（在 scripts / Makefile.autoconf 中）如何获取SYS_CONFIG_NAME的值（在 board / renesas / iwg20m_q7 / Kconfig中） ）。因此，一旦生成config.h文件（缺少正确的目录和SYS_CONFIG_NAME iwg20m_q7），这会导致失败
config.h
/* Automatically generated - do not edit */
#define CONFIG_BOARDDIR board/ -----> missing directory board/renesas/iwg20m_q7
#include <config_defaults.h>
#include <config_uncmd_spl.h>
#include <configs/.h> -----> missing SYS_CONFIG_NAME
#include <asm/config.h>
#include <config_fallbacks.h>
我已经尝试添加iwg20m_defconfig
CONFIG_ARM=y
CONFIG_RMOBILE=y
CONFIG_TARGET_IWG20M=y
CONFIG_SYS_ARCH="arm"
CONFIG_SYS_CPU="armv7"
CONFIG_SYS_SOC="iwg20m"
CONFIG_SYS_VENDOR="renesas"
CONFIG_SYS_BOARD="iwg20m_q7"
CONFIG_SYS_CONFIG_NAME="iwg20m_q7"

CONFIG_SPI_FLASH=y
CONFIG_SPI_FLASH_BAR=y
CONFIG_SH_SDHI=y
CONFIG_OF_LIBFDT=y

并重建，我看到 .config 文件也已正确更新，甚至已添加＆＃34; source＆＃34; board / renesas / iwg20m_q7 / Kconfig＆＃34; < / EM>＆＃34;转到 arch / arm / Kconfig 文件。
然而，问题仍未解决。有人可以帮我解决这个问题吗？感谢。
