Follow-ups

--- Michael Hennerich 2009-12-18 07:36:05

Fixed in trunk and 2009R1 branch

Avoid MEMDMA error during suspend

BF518 Instruction SRAM is 32kB and not 48kB

I have a BF518-EZBRD V1.0 with a YAMACHI IC149 type QFP Socket.

On this board the RTC oscillator sometimes fails to startup.

--- Vivi Li 2010-01-03 22:38:15

OK in both trunk and branch.

Close it.
