The patch titled
Blackfin SPI driver: move hard coded pin_req to board file
has been removed from the -mm tree. Its filename was
blackfin-spi-driver-move-hard-coded-pin_req-to-board-file.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Blackfin SPI driver: move hard coded pin_req to board file
From: Bryan Wu <[EMAIL PROTECTED]>
Remove some sort of bloaty code, try to get these pin_req arrays built at
compile-time
- move this static things to the blackfin board file
- add pin_req array to struct bfin5xx_spi_master
- tested on BF537/BF548 with SPI flash
