From: Sonic Zhang <sonic.zh...@analog.com>
- init hardware watchdog if applicable
- use CONFIG_SYS_MONITOR_LEN as the gd monitor len for Blackfin
- reserve u-boot memory at the top field of the RAM for Blackfin
- avoid refer to CONFIG_SYS_MONITOR_LEN, which is not defined by Blackfin
Signed-off-by: Sonic Zhang <sonic.zh...@analog.com>
---
v2-changes:
- make hardware watchdog init depend on BLACKFIN || M68K || MICROBLAZE || SH
- define watchdog init and reset macros for both software and hardware watchdog
