Re: [PATCH v3 01/20] mips: add support to restore exception vector base before booting linux

Am 21.01.20 um 09:18 schrieb Weijie Gao:

In U-Boot the exception vector base will be moved to top of memory, to be used to display register dump when exception occurs.

But some old linux kernel does not honor the base set in CP0_EBASE. A modified exception vector base will cause kernel crash.

This patch adds an option to enable reset exception vector base to its previous value, or a user configured value before booting linux kernel.
