[coreboot] [flashrom] r496 - trunk

[svn at coreboot.org]

Author: hailfinger
Date: 2009-05-11 22:04:30 +0200 (Mon, 11 May 2009)
New Revision: 496

Modified:
   trunk/stm50flw0x0x.c
Log:
Rename the STM50FLW register variable flash_addr used for block write
protect handling. All other chips call it wrprotect which is less
confusing.
As a side benefit, flash_addr is now a name usable for other stuff.
