Add lowlevel ag102 soc support.
Signed-off-by: Macpaul Lin macpaul@andestech.com
Changes for v2: - cpu.c: - 1. Remove unused variables. - 2. Replace while(1) in do_reset by hang(). - 3. Clean up other coding styles. - timer.c: remove unneccessary static declaration Changes for v3: - watchdog.S: add support macro in linkage.h
Applied to u-boot-nds32/master,
Thanks.
