Re: [U-Boot-Users] [PATCH][FOR 1.3.4] 85xx: Don't move interrupt vector to low memory

Moving the interrupt vectors to low memory can cause issues if the code
gets overwritten via some image loading command (tftp, boot*, etc.) and
interrupts (like the decrementer are enabled).
Oops? This is expected and normal behaviour. Did anybody complain
about this?

On 85xx there is no reason to copy the interrupt vectors to low memory
since we can run them in high memory since we are a Book-E core.
High memory means leave them in flash?
Then you will probably see nice crashes as soon as you erase U-Boot
for example to install a new version.
All references to flash memory must be relocated to RAM, including the
exception vectors, of course.

This is a fix for 1.3.4.
I don't think so. Seems to introduce a bug.
Best regards,
