From: Vipul Kumar Date: Mon, 5 Mar 2018 09:54:59 +0000 (+0530) Subject: arm64: zynqmp: nand: Fixed NAND erase issue for size 1GiB or more X-Git-Tag: v2018.05-rc1~9^2~6 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2453c695185f;p=u-boot arm64: zynqmp: nand: Fixed NAND erase issue for size 1GiB or more NAND erase was not happening for size 1GiB or more. Erase command was executing successfully but in actual, it was not erasing. This patch fixed erase issue for 1 GiB or more size nand.
