U-boot部分规格

Question

我目前正试图了解u-boot的组织方式，我想知道你是否可以帮助澄清配置中的某些部分 - ＆gt;包括/ CONFIGS / vexpress_aemv8a.h

#define CONFIG_SYS_TEXT_BASE            0x80000000 
/* from what I understand, this is where the code thinks it will be placed in memory */

#define CONFIG_SYS_INIT_SP_ADDR         (CONFIG_SYS_SDRAM_BASE + 0x7fff0)
/* I do not understand where this comes into play */

#define CPU_RELEASE_ADDR                (CONFIG_SYS_SDRAM_BASE + 0x7fff0)
/* I do not understand where this comes into play */

#define V2M_BASE                        0x80000000
/* I do not understand where this comes into play */

/* Miscellaneous configurable options */
#define CONFIG_SYS_LOAD_ADDR            (V2M_BASE + 0x10000000)
/* I do not understand where this comes into play */

如果您能详细说明这些内存区域的使用位置和方式，我将不胜感激。
