Hi,
As am I going through the MPC85xx reset.s code, I find this code snippet below. I find the Config_sys_monitor is the Text_Base Address in loaded in r3, The Start Offset is zero, I am not getting why we are subtracting the start_cont with start and that addr is loaded in the link register where we jump to.
So what does the address actually refer to? Please Explain.
/* Jump out the last 4K page and continue to 'normal' start */ #ifdef CONFIG_SYS_RAMBOOT b _start_cont #else /* Calculate absolute address in FLASH and jump there */ /*--------------------------------------------------------------*/ lis r3,CONFIG_SYS_MONITOR_BASE@h ori r3,r3,CONFIG_SYS_MONITOR_BASE@l addi r3,r3,_start_cont - _start + _START_OFFSET mtlr r3 blr #endif
_Start: .. .. .. _start_cont: .. .. ..

Could you please summarize the current state of adding UBI support?
Not much as before,
- Basic UBI command support. read/write/update volume. Of course you can create & remove the
volume.
- Send ubi device from environment variables instead of hard code
value.
I saw the NOR device support patch but not yet tested.
Are there the more?
Is it correct to assume we are targetting the 2008.12 release with this stuff?
Yes, I hope to merge it ASAP.
I'll post some last-minute UBI fixup patches soon (this week).
Best regards, Stefan
