Is there any additional info needed for this ?

Is there any additional info needed for this ? No other info needed, just time to review it. Please stop sending free pings, every patch will be reviewed. Cheers, ta

I see that the flash name contains info about the generation of the flash. Is the generation differentiated by a different device ID? If not, we can strip the "e" from the flash name. Looks like the flash has support for BP0-3 protection. You can try to add the flash locking flags and test the support with mtd-utils, if you're interested in this kind of support.

Add support for gd25lb256e. This device tested on IPQ5018 platform with dd from/to the flash for read/write respectly, and mtd erase for erasing the flash. Signed-off-by: Md Sadre Alam <mdalam@codeaurora.org> --- drivers/mtd/spi-nor/gigadevice.c | 3 +++ 1 file changed, 3 insertions(+)
