[Qemu-devel] [PATCH] vexpress fix flash device-width

[David Engraf]

The current implementation uses width = 4 and device-width = 2 for the 
flash configuration. When using u-boot or Linux, the flash is detected 
as 32 x 16 bit, thus the sector size is doubled to 512 KB. When u-boot 
sends a sector erase, only the first 256 KB are erased because the QEMU 
flash implementation uses the configured sector size of 256 KB and 
ignores the width and device-width ratio.

This patch will change device-width to 4, thus the width and 
device-width are equal and u-boot detects the flash as 32 x 32 bit with 
the correct sector size of 256 KB.
