Subject: Blackfin: bf537-stamp: declare parallel flash as ROM with XIP kernel
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=38e7673f24e6c19aba9ecff86760cb7981b91464;p=linux-beck.git

Blackfin: bf537-stamp: declare parallel flash as ROM with XIP kernel

When the kernel is executing out of parallel flash (XIP), we can't have
the flash go into an erase/programming cycle, otherwise the instruction
fetching steps fail and everything crashes.
