Hi,
I have a question about post memory test. According to the following code, even if memory size is greater than 256M, only 256M memory will be tested. Is it true or I missed something. Thanks a lot.
In U-BOOT-1.2.0 u-boot\post\drivers\memory.c,
int memory_post_test (int flags) { int ret = 0; DECLARE_GLOBAL_DATA_PTR; bd_t *bd = gd->bd; unsigned long memsize = (bd->bi_memsize >= 256 << 20 ? 256 << 20 : bd->bi_memsize) - (1 << 20);
if (flags & POST_SLOWTEST) { ret = memory_post_tests (CFG_SDRAM_BASE, memsize); } else { /* POST_NORMAL */
unsigned long i;
for (i = 0; i < (memsize >> 20) && ret == 0; i++) { if (ret == 0) ret = memory_post_tests (i << 20, 0x800); if (ret == 0) ret = memory_post_tests ((i << 20) + 0xff800, 0x800); } }
return ret; }
Best Regards dongy
