From f118fe5cf960702f5d57e4f60ec3e488215544dc Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Tue, 1 Dec 2015 16:18:20 +0800 Subject: [PATCH] altera_qspi: fix erase and write error code Fix erase and write error code, which should be "protected". From the "Embedded Peripherals IP User Guide" of Altera, The "Illegal write" flag indicates that a write instruction is targeting a protected sector on the flash memory. This bit is set to indicate that the IP has cancelled a write instruction. The "Illegal erase" flag indicates that an erase instruction has been set to a protected sector on the flash memory. This bit is set to indicate that the IP has cancelled the erase instruction.
