Subject: [U-Boot] OMAP3: proposal: dont piggy back on ROMCode interrupt vectors
Date: Tue, 13 Oct 2009 05:35:44 -0500 [thread overview]

Hi,
Current interrupt vectors[1] are piggy backing on OMAP3 ROM Code vectors
This has the disadvantage that "external boot" option of OMAP GP devices
for booting off NOR devices would probably not function as the interrupt
vectors are not setup.
I had faced this during the port of u-boot-v2 and had done an
implementation[2] for this. would we be interested in pulling this back
in for u-boot-v1? I suppose all OMAP3 devices could benefit from it.
Regards,
Nishanth Menon
