i am using the iMX6DL sabreauto EVK board with u-boot-2009.08
It is boot-up issue about _bss_start and _bss_end. _bss_start address is 0x278323D8 and _bss_end address is 0x2983C01C.
When EVK start with u-boot-2009.08, it take 950ms to reach to board_init() function becasue BSS area of iMX6 is large above 32Mbyte.
But BSS area of iMX35 is 30kbyte.
I have three questions, the first, where is the file in u-boot-2009.08 in order to set up
__bss_start and _end address?
The second, how do i decrease BSS area from 32Mbyte to 300Kbyte?
The third, can i fix the address about _end address as 0x278B23D8?
you can find the _bss_start variable and _end variable in start.S of u-boot-2009.08/cpu/arm_cortexa8
Please help me to resolve my concern.
