Hello all,
From following commit spi write/erase times out on gplugd which uses ATMEL
AT45DB041D spi flash.
commit f4f51a8ff894d34eb332f0d11f6c73c7bf509848 Author: Jagannadha Sutradharudu Teki jaganna@xilinx.com Date: Wed Oct 2 19:36:58 2013 +0530
sf: probe: Add support for erase sector selection flag
SECT_4K, SECT_32K and SECT_64K opeartions are performed to to specific flash by adding a SECT* flag on respective spi_flash_params.flag param.

Prior to this patch erase size was same as sector size; which is 64 * 1024 (64k). This 64K was replaced with 4k and timeout for erase started.
If following patch is applied write/erase works well (See bottom) on top of above commit. But similar change on latest git head still has some problem with spi erase.
Thanks Yogi
